A single instance of it exists for the entire network, and it is the\n * entity used to interact with Pools by Liquidity Providers who join and exit them, Traders who swap, and Asset\n * Managers who withdraw and deposit tokens.\n *\n * The `Vault`'s source code is split among a number of sub-contracts, with the goal of improving readability and making\n * understanding the system easier. Most sub-contracts have been marked as `abstract` to explicitly indicate that only\n * the full `Vault` is meant to be deployed.\n *\n * Roughly speaking, these are the contents of each sub-contract:\n *\n *  - `AssetManagers`: Pool token Asset Manager registry, and Asset Manager interactions.\n *  - `Fees`: set and compute protocol fees.\n *  - `FlashLoans`: flash loan transfers and fees.\n *  - `PoolBalances`: Pool joins and exits.\n *  - `PoolRegistry`: Pool registration, ID management, and basic queries.\n *  - `PoolTokens`: Pool token registration and registration, and balance queries.\n *  - `Swaps`: Pool swaps.\n *  - `UserBalance`: manage user balances (Internal Balance operations and external balance transfers)\n *  - `VaultAuthorization`: access control, relayers and signature validation.\n *\n * Additionally, the different Pool specializations are handled by the `GeneralPoolsBalance`,\n * `MinimalSwapInfoPoolsBalance` and `TwoTokenPoolsBalance` sub-contracts, which in turn make use of the\n * `BalanceAllocation` library.\n *\n * The most important goal of the `Vault` is to make token swaps use as little gas as possible. This is reflected in a\n * multitude of design decisions, from minor things like the format used to store Pool IDs, to major features such as\n * the different Pool specialization settings.\n *\n * Finally, the large number of tasks carried out by the Vault means its bytecode is very large, close to exceeding\n * the contract size limit imposed by EIP 170 (https://eips.ethereum.org/EIPS/eip-170). Manual tuning of the source code\n * was required to improve code generation and bring the bytecode size below this limit. This includes extensive\n * utilization of `internal` functions (particularly inside modifiers), usage of named return arguments, dedicated\n * storage access methods, dynamic revert reason generation, and usage of inline assembly, to name a few.\n */\ncontract Vault is VaultAuthorization, FlashLoans, Swaps {\n    constructor(\n        IAuthorizer authorizer,\n        IWETH weth,\n        uint256 pauseWindowDuration,\n        uint256 bufferPeriodDuration\n    ) VaultAuthorization(authorizer) AssetHelpers(weth) TemporarilyPausable(pauseWindowDuration, bufferPeriodDuration) {\n        // solhint-disable-previous-line no-empty-blocks\n    }\n\n    function setPaused(bool paused) external override nonReentrant authenticate {\n        _setPaused(paused);\n    }\n\n    // solhint-disable-next-line func-name-mixedcase\n    function WETH() external view override returns (IWETH) {\n        return _WETH();\n    }\n}\n"

TIP: For a detailed writeup see our guide https://forum.zeppelin.solutions/t/how-to-implement-erc20-supply-mechanisms/226[How to implement supply mechanisms]. We have followed general OpenZeppelin guidelines: functions revert instead of returning `false` on failure. This behavior is nonetheless conventional and does not conflict with the expectations of ERC20 applications. Additionally, an {Approval} event is emitted on calls to {transferFrom}. This allows applications to reconstruct the allowance for all accounts just by listening to said events. Other implementations of the EIP may not emit these events, as it isn't required by the specification. Finally, the non-standard {decreaseAllowance} and {increaseAllowance} functions have been added to mitigate the well-known issues around setting allowances. See {IERC20-approve}.",

We have followed general OpenZeppelin guidelines: functions revert instead of returning `false` on failure. This behavior is nonetheless conventional and does not conflict with the expectations of ERC20 applications. Additionally, an {Approval} event is emitted on calls to {transferFrom}. This allows applications to reconstruct the allowance for all accounts just by listening to said events. Other implementations of the EIP may not emit these events, as it isn't required by the specification.

No admin permissions are checked here: instead, this contract delegates that to the Vault's own Authorizer. Because this contract doesn't implement the swap hooks, derived contracts should generally inherit from BaseGeneralPool or BaseMinimalSwapInfoPool. Otherwise, subclasses must inherit from the corresponding interfaces and implement the swap callbacks themselves.",

The Vault will then take tokens from `sender` and add them to the Pool's balances, as well as collect the reported amount in protocol fees, which the pool should calculate based on `protocolSwapFeePercentage`. Protocol fees are reported and charged on join events so that the Pool is free of debt whenever new users join. `sender` is the account performing the join (from which tokens will be withdrawn), and `recipient` is the account designated to receive any benefits (typically pool shares). `currentBalances` contains the total balances for each token the Pool registered in the Vault, in the same order that `IVault.getPoolTokens` would return. `lastChangeBlock` is the last block in which *any* of the Pool's registered tokens last changed its total balance. `userData` contains any pool-specific instructions needed to perform the calculations, such as the type of join (e.g., proportional given an amount of pool shares, single-asset, multi-asset, etc.) Contracts implementing this function should check that the caller is indeed the Vault before performing any state-changing operations, such as minting pool shares."

In each individual swap, the caller determines either the amount of tokens sent to or received from the Pool, depending on the `kind` value. Returns an array with the net Vault asset balance deltas. Positive amounts represent tokens (or ETH) sent to the Vault, and negative amounts represent tokens (or ETH) sent by the Vault. Each delta corresponds to the asset at the same index in the `assets` array. Swaps are executed sequentially, in the order specified by the `swaps` array. Each array element describes a Pool, the token to be sent to this Pool, the token to receive from it, and an amount that is either `amountIn` or `amountOut` depending on the swap kind. Multihop swaps can be executed by passing an `amount` value of zero for a swap. This will cause the amount in/out of the previous swap to be used as the amount in for the current one. In a 'given in' swap, 'tokenIn' must equal the previous swap's `tokenOut`. For a 'given out' swap, `tokenOut` must equal the previous swap's `tokenIn`. The `assets` array contains the addresses of all assets involved in the swaps. These are either token addresses, or the IAsset sentinel value for ETH (the zero address). Each entry in the `swaps` array specifies tokens in and out by referencing an index in `assets`. Note that Pools never interact with ETH directly: it will be wrapped to or unwrapped from WETH by the Vault. Internal Balance usage, sender, and recipient are determined by the `funds` struct. The `limits` array specifies the minimum or maximum amount of each token the vault is allowed to transfer. `batchSwap` can be used to make a single swap, like `swap` does, but doing so requires more gas than the equivalent `swap` call.

This will trigger custom Pool behavior, which will typically ask for something in return from `sender` - often tokenized Pool shares. The amount of tokens that can be withdrawn is limited by the Pool's `cash` balance (see `getPoolTokenInfo`). If the caller is not `sender`, it must be an authorized relayer for them. The `tokens` and `minAmountsOut` arrays must have the same length, and each entry in these indicates the minimum token amount to receive for each token contract. The amounts to send are decided by the Pool and not the Vault: it just enforces these minimums. If exiting a Pool that holds WETH, it is possible to receive ETH directly: the Vault will do the unwrapping. To enable this mechanism, the IAsset sentinel value (the zero address) must be passed in the `assets` array instead of the WETH address. Note that it is not possible to combine ETH and WETH in the same exit. `assets` must have the same length and order as the array returned by `getPoolTokens`. This prevents issues when interacting with Pools that register and deregister tokens frequently.

Pools with no registered tokens cannot be exited. If `toInternalBalance` is true, the tokens will be deposited to `recipient`'s Internal Balance. Otherwise, an ERC20 transfer will be performed. Note that ETH cannot be deposited to Internal Balance: attempting to do so will trigger a revert. `minAmountsOut` is the minimum amount of tokens the user expects to get out of the Pool, for each token in the `tokens` array. This array must match the Pool's registered tokens. This causes the Vault to call the `IBasePool.onExitPool` hook on the Pool's contract, where Pools implement their own custom logic. This typically requires additional information from the user (such as the expected number of Pool shares to return). This can be encoded in the `userData` argument, which is ignored by the Vault and passed directly to the Pool's contract. Emits a `PoolBalanceChanged` event."

The `assets` and `maxAmountsIn` arrays must have the same length, and each entry indicates the maximum amount to send for each asset. The amounts to send are decided by the Pool and not the Vault: it just enforces these maximums. If joining a Pool that holds WETH, it is possible to send ETH directly: the Vault will do the wrapping. To enable this mechanism, the IAsset sentinel value (the zero address) must be passed in the `assets` array instead of the WETH address.

This makes it suitable to be called by off-chain applications via eth_call without needing to hold tokens, approve them for the Vault, or even know a user's address.

The `tokens` and `assetManagers` arrays must have the same length, and each entry in these indicates the Asset Manager for the corresponding token. Asset Managers can manage a Pool's tokens via `managePoolBalance`, depositing and withdrawing them directly, and can even set their balance to arbitrary amounts. They are therefore expected to be highly secured smart contracts with sound design principles, and the decision to register an Asset Manager should not be made lightly. Pools can choose not to assign an Asset Manager to a given token by passing in the zero address.

In each individual swap, the caller determines either the amount of tokens sent to or received from the Pool, depending on the `kind` value. Returns an array with the net Vault asset balance deltas. Positive amounts represent tokens (or ETH) sent to the Vault, and negative amounts represent tokens (or ETH) sent by the Vault. Each delta corresponds to the asset at the same index in the `assets` array. Swaps are executed sequentially, in the order specified by the `swaps` array. Each array element describes a Pool, the token to be sent to this Pool, the token to receive from it, and an amount that is either `amountIn` or `amountOut` depending on the swap kind. Multihop swaps can be executed by passing an `amount` value of zero for a swap. This will cause the amount in/out of the previous swap to be used as the amount in for the current one. In a 'given in' swap, 'tokenIn' must equal the previous swap's `tokenOut`. For a 'given out' swap, `tokenOut` must equal the previous swap's `tokenIn`. The `assets` array contains the addresses of all assets involved in the swaps. These are either token addresses, or the IAsset sentinel value for ETH (the zero address). Each entry in the `swaps` array specifies tokens in and out by referencing an index in `assets`. Note that Pools never interact with ETH directly: it will be wrapped to or unwrapped from WETH by the Vault. Internal Balance usage, sender, and recipient are determined by the `funds` struct. The `limits` array specifies the minimum or maximum amount of each token the vault is allowed to transfer. `batchSwap` can be used to make a single swap, like `swap` does, but doing so requires more gas than the equivalent `swap` call.

The amount of tokens that can be withdrawn is limited by the Pool's `cash` balance (see `getPoolTokenInfo`). If the caller is not `sender`, it must be an authorized relayer for them. The `tokens` and `minAmountsOut` arrays must have the same length, and each entry in these indicates the minimum token amount to receive for each token contract. The amounts to send are decided by the Pool and not the Vault: it just enforces these minimums. If exiting a Pool that holds WETH, it is possible to receive ETH directly: the Vault will do the unwrapping. To enable this mechanism, the IAsset sentinel value (the zero address) must be passed in the `assets` array instead of the WETH address. Note that it is not possible to combine ETH and WETH in the same exit. `assets` must have the same length and order as the array returned by `getPoolTokens`. This prevents issues when interacting with Pools that register and deregister tokens frequently. If receiving ETH however, the array must be sorted *before* replacing the WETH address with the ETH sentinel value (the zero address), which means the final `assets` array might not be sorted. Pools with no registered tokens cannot be exited. If `toInternalBalance` is true, the tokens will be deposited to `recipient`'s Internal Balance. Otherwise, an ERC20 transfer will be performed. Note that ETH cannot be deposited to Internal Balance: attempting to do so will trigger a revert. `minAmountsOut` is the minimum amount of tokens the user expects to get out of the Pool, for each token in the `tokens` array. This array must match the Pool's registered tokens. This causes the Vault to call the `IBasePool.onExitPool` hook on the Pool's contract, where Pools implement their own custom logic.

No action can ever cause a Pool's token `cash`, `managed` or `total` balance to be greater than 2^112 - 1. `lastChangeBlock` is the number of the block in which `token`'s total balance was last modified (via either a join, exit, swap, or Asset Manager update). This value is useful to avoid so-called 'sandwich attacks', for example when developing price oracles.

To enable this mechanism, the IAsset sentinel value (the zero address) must be passed in the `assets` array instead of the WETH address. Note that it is not possible to combine ETH and WETH in the same join. Any excess ETH will be sent back to the caller (not the sender, which is important for relayers). `assets` must have the same length and order as the array returned by `getPoolTokens`. This prevents issues when interacting with Pools that register and deregister tokens frequently. If sending ETH however, the array must be sorted *before* replacing the WETH address with the ETH sentinel value (the zero address), which means the final `assets` array might not be sorted. Pools with no registered tokens cannot be joined.

This makes it suitable to be called by off-chain applications via eth_call without needing to hold tokens, approve them for the Vault, or even know a user's address.

Asset Managers can manage a Pool's tokens via `managePoolBalance`, depositing and withdrawing them directly, and can even set their balance to arbitrary amounts. They are therefore expected to be highly secured smart contracts with sound design principles, and the decision to register an Asset Manager should not be made lightly.

Positive amounts represent tokens (or ETH) sent to the Vault, and negative amounts represent tokens (or ETH) sent by the Vault. Each delta corresponds to the asset at the same index in the `assets` array. Swaps are executed sequentially, in the order specified by the `swaps` array. Each array element describes a Pool, the token to be sent to this Pool, the token to receive from it, and an amount that is either `amountIn` or `amountOut` depending on the swap kind. Multihop swaps can be executed by passing an `amount` value of zero for a swap. This will cause the amount in/out of the previous swap to be used as the amount in for the current one. In a 'given in' swap, 'tokenIn' must equal the previous swap's `tokenOut`. For a 'given out' swap, `tokenOut` must equal the previous swap's `tokenIn`. The `assets` array contains the addresses of all assets involved in the swaps. These are either token addresses, or the IAsset sentinel value for ETH (the zero address). Each entry in the `swaps` array specifies tokens in and out by referencing an index in `assets`. Note that Pools never interact with ETH directly: it will be wrapped to or unwrapped from WETH by the Vault. Internal Balance usage, sender, and recipient are determined by the `funds` struct. The `limits` array specifies the minimum or maximum amount of each token the vault is allowed to transfer. `batchSwap` can be used to make a single swap, like `swap` does, but doing so requires more gas than the equivalent `swap` call.

This will trigger custom Pool behavior, which will typically ask for something in return from `sender` - often tokenized Pool shares. The amount of tokens that can be withdrawn is limited by the Pool's `cash` balance (see `getPoolTokenInfo`). If the caller is not `sender`, it must be an authorized relayer for them. The `tokens` and `minAmountsOut` arrays must have the same length, and each entry in these indicates the minimum token amount to receive for each token contract. The amounts to send are decided by the Pool and not the Vault: it just enforces these minimums. If exiting a Pool that holds WETH, it is possible to receive ETH directly: the Vault will do the unwrapping. To enable this mechanism, the IAsset sentinel value (the zero address) must be passed in the `assets` array instead of the WETH address. Note that it is not possible to combine ETH and WETH in the same exit. `assets` must have the same length and order as the array returned by `getPoolTokens`. This prevents issues when interacting with Pools that register and deregister tokens frequently. If receiving ETH however, the array must be sorted *before* replacing the WETH address with the ETH sentinel value (the zero address), which means the final `assets` array might not be sorted. Pools with no registered tokens cannot be exited. If `toInternalBalance` is true, the tokens will be deposited to `recipient`'s Internal Balance. Otherwise, an ERC20 transfer will be performed. Note that ETH cannot be deposited to Internal Balance: attempting to do so will trigger a revert. `minAmountsOut` is the minimum amount of tokens the user expects to get out of the Pool, for each token in the `tokens` array. This array must match the Pool's registered tokens. This causes the Vault to call the `IBasePool.onExitPool` hook on the Pool's contract, where Pools implement their own custom logic. This typically requires additional information from the user (such as the expected number of Pool shares to return). This can be encoded in the `userData` argument, which is ignored by the Vault and passed directly to the Pool's contract. Emits a `PoolBalanceChanged` event."

The `assets` and `maxAmountsIn` arrays must have the same length, and each entry indicates the maximum amount to send for each asset. The amounts to send are decided by the Pool and not the Vault: it just enforces these maximums. If joining a Pool that holds WETH, it is possible to send ETH directly: the Vault will do the wrapping.

The `tokens` and `assetManagers` arrays must have the same length, and each entry in these indicates the Asset Manager for the corresponding token. Asset Managers can manage a Pool's tokens via `managePoolBalance`, depositing and withdrawing them directly, and can even set their balance to arbitrary amounts. They are therefore expected to be highly secured smart contracts with sound design principles, and the decision to register an Asset Manager should not be made lightly. Pools can choose not to assign an Asset Manager to a given token by passing in the zero address.

In each individual swap, the caller determines either the amount of tokens sent to or received from the Pool, depending on the `kind` value. Returns an array with the net Vault asset balance deltas. Positive amounts represent tokens (or ETH) sent to the Vault, and negative amounts represent tokens (or ETH) sent by the Vault. Each delta corresponds to the asset at the same index in the `assets` array. Swaps are executed sequentially, in the order specified by the `swaps` array. Each array element describes a Pool, the token to be sent to this Pool, the token to receive from it, and an amount that is either `amountIn` or `amountOut` depending on the swap kind. Multihop swaps can be executed by passing an `amount` value of zero for a swap. This will cause the amount in/out of the previous swap to be used as the amount in for the current one. In a 'given in' swap, 'tokenIn' must equal the previous swap's `tokenOut`. For a 'given out' swap, `tokenOut` must equal the previous swap's `tokenIn`. The `assets` array contains the addresses of all assets involved in the swaps. These are either token addresses, or the IAsset sentinel value for ETH (the zero address). Each entry in the `swaps` array specifies tokens in and out by referencing an index in `assets`. Note that Pools never interact with ETH directly: it will be wrapped to or unwrapped from WETH by the Vault. Internal Balance usage, sender, and recipient are determined by the `funds` struct. The `limits` array specifies the minimum or maximum amount of each token the vault is allowed to transfer. `batchSwap` can be used to make a single swap, like `swap` does, but doing so requires more gas than the equivalent `swap` call.

The `tokens` and `minAmountsOut` arrays must have the same length, and each entry in these indicates the minimum token amount to receive for each token contract. The amounts to send are decided by the Pool and not the Vault: it just enforces these minimums. If exiting a Pool that holds WETH, it is possible to receive ETH directly: the Vault will do the unwrapping. To enable this mechanism, the IAsset sentinel value (the zero address) must be passed in the `assets` array instead of the WETH address.

Note that ETH cannot be deposited to Internal Balance: attempting to do so will trigger a revert. `minAmountsOut` is the minimum amount of tokens the user expects to get out of the Pool, for each token in the `tokens` array. This array must match the Pool's registered tokens. This causes the Vault to call the `IBasePool.onExitPool` hook on the Pool's contract, where Pools implement their own custom logic.

Positive amounts represent tokens (or ETH) sent to the Vault, and negative amounts represent tokens (or ETH) sent by the Vault. Each delta corresponds to the asset at the same index in the `assets` array. Swaps are executed sequentially, in the order specified by the `swaps` array. Each array element describes a Pool, the token to be sent to this Pool, the token to receive from it, and an amount that is either `amountIn` or `amountOut` depending on the swap kind. Multihop swaps can be executed by passing an `amount` value of zero for a swap. This will cause the amount in/out of the previous swap to be used as the amount in for the current one. In a 'given in' swap, 'tokenIn' must equal the previous swap's `tokenOut`. For a 'given out' swap, `tokenOut` must equal the previous swap's `tokenIn`. The `assets` array contains the addresses of all assets involved in the swaps. These are either token addresses, or the IAsset sentinel value for ETH (the zero address). Each entry in the `swaps` array specifies tokens in and out by referencing an index in `assets`. Note that Pools never interact with ETH directly: it will be wrapped to or unwrapped from WETH by the Vault. Internal Balance usage, sender, and recipient are determined by the `funds` struct. The `limits` array specifies the minimum or maximum amount of each token the vault is allowed to transfer. `batchSwap` can be used to make a single swap, like `swap` does, but doing so requires more gas than the equivalent `swap` call.

Positive amounts represent tokens (or ETH) sent to the Vault, and negative amounts represent tokens (or ETH) sent by the Vault. Each delta corresponds to the asset at the same index in the `assets` array. Swaps are executed sequentially, in the order specified by the `swaps` array. Each array element describes a Pool, the token to be sent to this Pool, the token to receive from it, and an amount that is either `amountIn` or `amountOut` depending on the swap kind. Multihop swaps can be executed by passing an `amount` value of zero for a swap. This will cause the amount in/out of the previous swap to be used as the amount in for the current one. In a 'given in' swap, 'tokenIn' must equal the previous swap's `tokenOut`. For a 'given out' swap, `tokenOut` must equal the previous swap's `tokenIn`. The `assets` array contains the addresses of all assets involved in the swaps. These are either token addresses, or the IAsset sentinel value for ETH (the zero address). Each entry in the `swaps` array specifies tokens in and out by referencing an index in `assets`. Note that Pools never interact with ETH directly: it will be wrapped to or unwrapped from WETH by the Vault. Internal Balance usage, sender, and recipient are determined by the `funds` struct.

The `tokens` and `minAmountsOut` arrays must have the same length, and each entry in these indicates the minimum token amount to receive for each token contract. The amounts to send are decided by the Pool and not the Vault: it just enforces these minimums. If exiting a Pool that holds WETH, it is possible to receive ETH directly: the Vault will do the unwrapping. To enable this mechanism, the IAsset sentinel value (the zero address) must be passed in the `assets` array instead of the WETH address.

Positive amounts represent tokens (or ETH) sent to the Vault, and negative amounts represent tokens (or ETH) sent by the Vault. Each delta corresponds to the asset at the same index in the `assets` array. Swaps are executed sequentially, in the order specified by the `swaps` array. Each array element describes a Pool, the token to be sent to this Pool, the token to receive from it, and an amount that is either `amountIn` or `amountOut` depending on the swap kind. Multihop swaps can be executed by passing an `amount` value of zero for a swap. This will cause the amount in/out of the previous swap to be used as the amount in for the current one. In a 'given in' swap, 'tokenIn' must equal the previous swap's `tokenOut`. For a 'given out' swap, `tokenOut` must equal the previous swap's `tokenIn`. The `assets` array contains the addresses of all assets involved in the swaps. These are either token addresses, or the IAsset sentinel value for ETH (the zero address). Each entry in the `swaps` array specifies tokens in and out by referencing an index in `assets`. Note that Pools never interact with ETH directly: it will be wrapped to or unwrapped from WETH by the Vault. Internal Balance usage, sender, and recipient are determined by the `funds` struct. The `limits` array specifies the minimum or maximum amount of each token the vault is allowed to transfer. `batchSwap` can be used to make a single swap, like `swap` does, but doing so requires more gas than the equivalent `swap` call.

This will trigger custom Pool behavior, which will typically ask for something in return from `sender` - often tokenized Pool shares. The amount of tokens that can be withdrawn is limited by the Pool's `cash` balance (see `getPoolTokenInfo`). If the caller is not `sender`, it must be an authorized relayer for them. The `tokens` and `minAmountsOut` arrays must have the same length, and each entry in these indicates the minimum token amount to receive for each token contract. The amounts to send are decided by the Pool and not the Vault: it just enforces these minimums. If exiting a Pool that holds WETH, it is possible to receive ETH directly: the Vault will do the unwrapping. To enable this mechanism, the IAsset sentinel value (the zero address) must be passed in the `assets` array instead of the WETH address. Note that it is not possible to combine ETH and WETH in the same exit. `assets` must have the same length and order as the array returned by `getPoolTokens`. This prevents issues when interacting with Pools that register and deregister tokens frequently. If receiving ETH however, the array must be sorted *before* replacing the WETH address with the ETH sentinel value (the zero address), which means the final `assets` array might not be sorted. Pools with no registered tokens cannot be exited. If `toInternalBalance` is true, the tokens will be deposited to `recipient`'s Internal Balance. Otherwise, an ERC20 transfer will be performed. Note that ETH cannot be deposited to Internal Balance: attempting to do so will trigger a revert. `minAmountsOut` is the minimum amount of tokens the user expects to get out of the Pool, for each token in the `tokens` array. This array must match the Pool's registered tokens. This causes the Vault to call the `IBasePool.onExitPool` hook on the Pool's contract, where Pools implement their own custom logic. This typically requires additional information from the user (such as the expected number of Pool shares to return). This can be encoded in the `userData` argument, which is ignored by the Vault and passed directly to the Pool's contract. Emits a `PoolBalanceChanged` event."

This value is useful to avoid so-called 'sandwich attacks', for example when developing price oracles.

The amounts to send are decided by the Pool and not the Vault: it just enforces these maximums. If joining a Pool that holds WETH, it is possible to send ETH directly: the Vault will do the wrapping. To enable this mechanism, the IAsset sentinel value (the zero address) must be passed in the `assets` array instead of the WETH address. Note that it is not possible to combine ETH and WETH in the same join. Any excess ETH will be sent back to the caller (not the sender, which is important for relayers). `assets` must have the same length and order as the array returned by `getPoolTokens`. This prevents issues when interacting with Pools that register and deregister tokens frequently. If sending ETH however, the array must be sorted *before* replacing the WETH address with the ETH sentinel value (the zero address), which means the final `assets` array might not be sorted. Pools with no registered tokens cannot be joined. If `fromInternalBalance` is true, the caller's Internal Balance will be preferred: ERC20 transfers will only be made for the difference between the requested amount and Internal Balance (if any). Note that ETH cannot be withdrawn from Internal Balance: attempting to do so will trigger a revert. This causes the Vault to call the `IBasePool.onJoinPool` hook on the Pool's contract, where Pools implement their own custom logic. This typically requires additional information from the user (such as the expected number of Pool shares). This can be encoded in the `userData` argument, which is ignored by the Vault and passed directly to the Pool's contract, as is `recipient`. Emits a `PoolBalanceChanged` event."

This makes it suitable to be called by off-chain applications via eth_call without needing to hold tokens, approve them for the Vault, or even know a user's address.

For Pools with the Two Token specialization, `tokens` must have a length of two, that is, both tokens must be registered in the same `registerTokens` call, and they must be sorted in ascending order. The `tokens` and `assetManagers` arrays must have the same length, and each entry in these indicates the Asset Manager for the corresponding token. Asset Managers can manage a Pool's tokens via `managePoolBalance`, depositing and withdrawing them directly, and can even set their balance to arbitrary amounts. They are therefore expected to be highly secured smart contracts with sound design principles, and the decision to register an Asset Manager should not be made lightly. Pools can choose not to assign an Asset Manager to a given token by passing in the zero address. Once an Asset Manager is set, it cannot be changed except by deregistering the associated token and registering again with a different Asset Manager. Emits a `TokensRegistered` event."

The `tokens` and `minAmountsOut` arrays must have the same length, and each entry in these indicates the minimum token amount to receive for each token contract. The amounts to send are decided by the Pool and not the Vault: it just enforces these minimums. If exiting a Pool that holds WETH, it is possible to receive ETH directly: the Vault will do the unwrapping. To enable this mechanism, the IAsset sentinel value (the zero address) must be passed in the `assets` array instead of the WETH address. Note that it is not possible to combine ETH and WETH in the same exit. `assets` must have the same length and order as the array returned by `getPoolTokens`. This prevents issues when interacting with Pools that register and deregister tokens frequently.

Pools with no registered tokens cannot be exited. If `toInternalBalance` is true, the tokens will be deposited to `recipient`'s Internal Balance. Otherwise, an ERC20 transfer will be performed. Note that ETH cannot be deposited to Internal Balance: attempting to do so will trigger a revert. `minAmountsOut` is the minimum amount of tokens the user expects to get out of the Pool, for each token in the `tokens` array. This array must match the Pool's registered tokens. This causes the Vault to call the `IBasePool.onExitPool` hook on the Pool's contract, where Pools implement their own custom logic.

This value is useful to avoid so-called 'sandwich attacks', for example when developing price oracles.

Any excess ETH will be sent back to the caller (not the sender, which is important for relayers). `assets` must have the same length and order as the array returned by `getPoolTokens`.

Asset Managers can manage a Pool's tokens via `managePoolBalance`, depositing and withdrawing them directly, and can even set their balance to arbitrary amounts. They are therefore expected to be highly secured smart contracts with sound design principles, and the decision to register an Asset Manager should not be made lightly.

This is reflected in the different methods available: 'increaseCash'\\n// and 'decreaseCash' for swaps and add/remove liquidity events, and 'cashToManaged' and 'managedToCash' for events\\n// transferring funds to and from the Asset Manager.\\n//\\n// The Vault disallows the Pool's 'cash' from becoming negative.

Positive amounts represent tokens (or ETH) sent to the Vault, and negative amounts represent tokens (or ETH) sent by the Vault. Each delta corresponds to the asset at the same index in the `assets` array. Swaps are executed sequentially, in the order specified by the `swaps` array. Each array element describes a Pool, the token to be sent to this Pool, the token to receive from it, and an amount that is either `amountIn` or `amountOut` depending on the swap kind. Multihop swaps can be executed by passing an `amount` value of zero for a swap. This will cause the amount in/out of the previous swap to be used as the amount in for the current one. In a 'given in' swap, 'tokenIn' must equal the previous swap's `tokenOut`. For a 'given out' swap, `tokenOut` must equal the previous swap's `tokenIn`. The `assets` array contains the addresses of all assets involved in the swaps. These are either token addresses, or the IAsset sentinel value for ETH (the zero address). Each entry in the `swaps` array specifies tokens in and out by referencing an index in `assets`. Note that Pools never interact with ETH directly: it will be wrapped to or unwrapped from WETH by the Vault. Internal Balance usage, sender, and recipient are determined by the `funds` struct.

Positive amounts represent tokens (or ETH) sent to the Vault, and negative amounts represent tokens (or ETH) sent by the Vault. Each delta corresponds to the asset at the same index in the `assets` array. Swaps are executed sequentially, in the order specified by the `swaps` array. Each array element describes a Pool, the token to be sent to this Pool, the token to receive from it, and an amount that is either `amountIn` or `amountOut` depending on the swap kind. Multihop swaps can be executed by passing an `amount` value of zero for a swap. This will cause the amount in/out of the previous swap to be used as the amount in for the current one. In a 'given in' swap, 'tokenIn' must equal the previous swap's `tokenOut`. For a 'given out' swap, `tokenOut` must equal the previous swap's `tokenIn`. The `assets` array contains the addresses of all assets involved in the swaps. These are either token addresses, or the IAsset sentinel value for ETH (the zero address). Each entry in the `swaps` array specifies tokens in and out by referencing an index in `assets`. Note that Pools never interact with ETH directly: it will be wrapped to or unwrapped from WETH by the Vault. Internal Balance usage, sender, and recipient are determined by the `funds` struct. The `limits` array specifies the minimum or maximum amount of each token the vault is allowed to transfer. `batchSwap` can be used to make a single swap, like `swap` does, but doing so requires more gas than the equivalent `swap` call.

The `tokens` and `minAmountsOut` arrays must have the same length, and each entry in these indicates the minimum token amount to receive for each token contract. The amounts to send are decided by the Pool and not the Vault: it just enforces these minimums. If exiting a Pool that holds WETH, it is possible to receive ETH directly: the Vault will do the unwrapping. To enable this mechanism, the IAsset sentinel value (the zero address) must be passed in the `assets` array instead of the WETH address. Note that it is not possible to combine ETH and WETH in the same exit. `assets` must have the same length and order as the array returned by `getPoolTokens`.

Pools with no registered tokens cannot be exited. If `toInternalBalance` is true, the tokens will be deposited to `recipient`'s Internal Balance. Otherwise, an ERC20 transfer will be performed. Note that ETH cannot be deposited to Internal Balance: attempting to do so will trigger a revert. `minAmountsOut` is the minimum amount of tokens the user expects to get out of the Pool, for each token in the `tokens` array. This array must match the Pool's registered tokens. This causes the Vault to call the `IBasePool.onExitPool` hook on the Pool's contract, where Pools implement their own custom logic.

This value is useful to avoid so-called 'sandwich attacks', for example when developing price oracles.

Any excess ETH will be sent back to the caller (not the sender, which is important for relayers). `assets` must have the same length and order as the array returned by `getPoolTokens`.

This makes it suitable to be called by off-chain applications via eth_call without needing to hold tokens, approve them for the Vault, or even know a user's address.

Each delta corresponds to the asset at the same index in the `assets` array. Swaps are executed sequentially, in the order specified by the `swaps` array. Each array element describes a Pool, the token to be sent to this Pool, the token to receive from it, and an amount that is either `amountIn` or `amountOut` depending on the swap kind. Multihop swaps can be executed by passing an `amount` value of zero for a swap. This will cause the amount in/out of the previous swap to be used as the amount in for the current one. In a 'given in' swap, 'tokenIn' must equal the previous swap's `tokenOut`. For a 'given out' swap, `tokenOut` must equal the previous swap's `tokenIn`. The `assets` array contains the addresses of all assets involved in the swaps. These are either token addresses, or the IAsset sentinel value for ETH (the zero address).

or multiple Pools. In each individual swap, the caller determines either the amount of tokens sent to or received from the Pool, depending on the `kind` value. Returns an array with the net Vault asset balance deltas. Positive amounts represent tokens (or ETH) sent to the Vault, and negative amounts represent tokens (or ETH) sent by the Vault. Each delta corresponds to the asset at the same index in the `assets` array. Swaps are executed sequentially, in the order specified by the `swaps` array. Each array element describes a Pool, the token to be sent to this Pool, the token to receive from it, and an amount that is either `amountIn` or `amountOut` depending on the swap kind. Multihop swaps can be executed by passing an `amount` value of zero for a swap. This will cause the amount in/out of the previous swap to be used as the amount in for the current one. In a 'given in' swap, 'tokenIn' must equal the previous swap's `tokenOut`. For a 'given out' swap, `tokenOut` must equal the previous swap's `tokenIn`. The `assets` array contains the addresses of all assets involved in the swaps. These are either token addresses, or the IAsset sentinel value for ETH (the zero address). Each entry in the `swaps` array specifies tokens in and out by referencing an index in `assets`. Note that Pools never interact with ETH directly: it will be wrapped to or unwrapped from WETH by the Vault. Internal Balance usage, sender, and recipient are determined by the `funds` struct. The `limits` array specifies the minimum or maximum amount of each token the vault is allowed to transfer. `batchSwap` can be used to make a single swap, like `swap` does, but doing so requires more gas than the equivalent `swap` call. Emits `Swap` events.\"},\"changeAuthorizer(address)\":{\"details\":\"Sets a new Authorizer for the Vault. The caller must be allowed by the current Authorizer to do this.

This will trigger custom Pool behavior, which will typically ask for something in return from `sender` - often tokenized Pool shares. The amount of tokens that can be withdrawn is limited by the Pool's `cash` balance (see `getPoolTokenInfo`). If the caller is not `sender`, it must be an authorized relayer for them. The `tokens` and `minAmountsOut` arrays must have the same length, and each entry in these indicates the minimum token amount to receive for each token contract. The amounts to send are decided by the Pool and not the Vault: it just enforces these minimums. If exiting a Pool that holds WETH, it is possible to receive ETH directly: the Vault will do the unwrapping. To enable this mechanism, the IAsset sentinel value (the zero address) must be passed in the `assets` array instead of the WETH address. Note that it is not possible to combine ETH and WETH in the same exit. `assets` must have the same length and order as the array returned by `getPoolTokens`. This prevents issues when interacting with Pools that register and deregister tokens frequently. If receiving ETH however, the array must be sorted *before* replacing the WETH address with the ETH sentinel value (the zero address), which means the final `assets` array might not be sorted. Pools with no registered tokens cannot be exited. If `toInternalBalance` is true, the tokens will be deposited to `recipient`'s Internal Balance. Otherwise, an ERC20 transfer will be performed. Note that ETH cannot be deposited to Internal Balance: attempting to do so will trigger a revert. `minAmountsOut` is the minimum amount of tokens the user expects to get out of the Pool, for each token in the `tokens` array. This array must match the Pool's registered tokens. This causes the Vault to call the `IBasePool.onExitPool` hook on the Pool's contract, where Pools implement their own custom logic.

No action can ever cause a Pool's token `cash`, `managed` or `total` balance to be greater than 2^112 - 1. `lastChangeBlock` is the number of the block in which `token`'s total balance was last modified (via either a join, exit, swap, or Asset Manager update). This value is useful to avoid so-called 'sandwich attacks', for example when developing price oracles.

Calls to `registerTokens` and `deregisterTokens` may change this order. If a Pool only registers tokens once, and these are sorted in ascending order, they will be stored in the same order as passed to `registerTokens`.

To enable this mechanism, the IAsset sentinel value (the zero address) must be passed in the `assets` array instead of the WETH address. Note that it is not possible to combine ETH and WETH in the same join. Any excess ETH will be sent back to the caller (not the sender, which is important for relayers). `assets` must have the same length and order as the array returned by `getPoolTokens`. This prevents issues when interacting with Pools that register and deregister tokens frequently. If sending ETH however, the array must be sorted *before* replacing the WETH address with the ETH sentinel value (the zero address), which means the final `assets` array might not be sorted.

Each token can only be registered once. For Pools with the Two Token specialization, `tokens` must have a length of two, that is, both tokens must be registered in the same `registerTokens` call, and they must be sorted in ascending order. The `tokens` and `assetManagers` arrays must have the same length, and each entry in these indicates the Asset Manager for the corresponding token. Asset Managers can manage a Pool's tokens via `managePoolBalance`, depositing and withdrawing them directly, and can even set their balance to arbitrary amounts. They are therefore expected to be highly secured smart contracts with sound design principles, and the decision to register an Asset Manager should not be made lightly. Pools can choose not to assign an Asset Manager to a given token by passing in the zero address. Once an Asset Manager is set, it cannot be changed except by deregistering the associated token and registering again with a different Asset Manager.

This is reflected in the different methods available: 'increaseCash'\\n// and 'decreaseCash' for swaps and add/remove liquidity events, and 'cashToManaged' and 'managedToCash' for events\\n// transferring funds to and from the Asset Manager.\\n//\\n// The Vault disallows the Pool's 'cash' from becoming negative.

Each delta corresponds to the asset at the same index in the `assets` array. Swaps are executed sequentially, in the order specified by the `swaps` array. Each array element describes a Pool, the token to be sent to this Pool, the token to receive from it, and an amount that is either `amountIn` or `amountOut` depending on the swap kind. Multihop swaps can be executed by passing an `amount` value of zero for a swap. This will cause the amount in/out of the previous swap to be used as the amount in for the current one. In a 'given in' swap, 'tokenIn' must equal the previous swap's `tokenOut`. For a 'given out' swap, `tokenOut` must equal the previous swap's `tokenIn`. The `assets` array contains the addresses of all assets involved in the swaps. These are either token addresses, or the IAsset sentinel value for ETH (the zero address).

or multiple Pools. In each individual swap, the caller determines either the amount of tokens sent to or received from the Pool, depending on the `kind` value. Returns an array with the net Vault asset balance deltas. Positive amounts represent tokens (or ETH) sent to the Vault, and negative amounts represent tokens (or ETH) sent by the Vault. Each delta corresponds to the asset at the same index in the `assets` array. Swaps are executed sequentially, in the order specified by the `swaps` array. Each array element describes a Pool, the token to be sent to this Pool, the token to receive from it, and an amount that is either `amountIn` or `amountOut` depending on the swap kind. Multihop swaps can be executed by passing an `amount` value of zero for a swap. This will cause the amount in/out of the previous swap to be used as the amount in for the current one. In a 'given in' swap, 'tokenIn' must equal the previous swap's `tokenOut`. For a 'given out' swap, `tokenOut` must equal the previous swap's `tokenIn`. The `assets` array contains the addresses of all assets involved in the swaps. These are either token addresses, or the IAsset sentinel value for ETH (the zero address). Each entry in the `swaps` array specifies tokens in and out by referencing an index in `assets`. Note that Pools never interact with ETH directly: it will be wrapped to or unwrapped from WETH by the Vault. Internal Balance usage, sender, and recipient are determined by the `funds` struct. The `limits` array specifies the minimum or maximum amount of each token the vault is allowed to transfer. `batchSwap` can be used to make a single swap, like `swap` does, but doing so requires more gas than the equivalent `swap` call. Emits `Swap` events.\"},\"changeAuthorizer(address)\":{\"details\":\"Sets a new Authorizer for the Vault. The caller must be allowed by the current Authorizer to do this.

For Pools with the Two Token specialization, `tokens` must have a length of two, that is, both tokens must be deregistered in the same `deregisterTokens` call. A deregistered token can be re-registered later on, possibly with a different Asset Manager.

This will trigger custom Pool behavior, which will typically ask for something in return from `sender` - often tokenized Pool shares. The amount of tokens that can be withdrawn is limited by the Pool's `cash` balance (see `getPoolTokenInfo`). If the caller is not `sender`, it must be an authorized relayer for them. The `tokens` and `minAmountsOut` arrays must have the same length, and each entry in these indicates the minimum token amount to receive for each token contract. The amounts to send are decided by the Pool and not the Vault: it just enforces these minimums. If exiting a Pool that holds WETH, it is possible to receive ETH directly: the Vault will do the unwrapping. To enable this mechanism, the IAsset sentinel value (the zero address) must be passed in the `assets` array instead of the WETH address. Note that it is not possible to combine ETH and WETH in the same exit. `assets` must have the same length and order as the array returned by `getPoolTokens`. This prevents issues when interacting with Pools that register and deregister tokens frequently. If receiving ETH however, the array must be sorted *before* replacing the WETH address with the ETH sentinel value (the zero address), which means the final `assets` array might not be sorted. Pools with no registered tokens cannot be exited. If `toInternalBalance` is true, the tokens will be deposited to `recipient`'s Internal Balance. Otherwise, an ERC20 transfer will be performed. Note that ETH cannot be deposited to Internal Balance: attempting to do so will trigger a revert. `minAmountsOut` is the minimum amount of tokens the user expects to get out of the Pool, for each token in the `tokens` array. This array must match the Pool's registered tokens. This causes the Vault to call the `IBasePool.onExitPool` hook on the Pool's contract, where Pools implement their own custom logic. This typically requires additional information from the user (such as the expected number of Pool shares to return). This can be encoded in the `userData` argument, which is ignored by the Vault and passed directly to the Pool's contract.

No action can ever cause a Pool's token `cash`, `managed` or `total` balance to be greater than 2^112 - 1. `lastChangeBlock` is the number of the block in which `token`'s total balance was last modified (via either a join, exit, swap, or Asset Manager update). This value is useful to avoid so-called 'sandwich attacks', for example when developing price oracles. A change of zero (e.g. caused by a swap with amount zero) is considered a change for this purpose, and will update `lastChangeBlock`. `assetManager` is the Pool's token Asset Manager.\"},\"getPoolTokens(bytes32)\":{\"details\":\"Returns a Pool's registered tokens, the total balance for each, and the latest block when *any* of the tokens' `balances` changed.

Calls to `registerTokens` and `deregisterTokens` may change this order.

If `fromInternalBalance` is true, the caller's Internal Balance will be preferred: ERC20 transfers will only be made for the difference between the requested amount and Internal Balance (if any). Note that ETH cannot be withdrawn from Internal Balance: attempting to do so will trigger a revert. This causes the Vault to call the `IBasePool.onJoinPool` hook on the Pool's contract, where Pools implement their own custom logic. This typically requires additional information from the user (such as the expected number of Pool shares). This can be encoded in the `userData` argument, which is ignored by the Vault and passed directly to the Pool's contract, as is `recipient`. Emits a `PoolBalanceChanged` event.\"},\"managePoolBalance((uint8,bytes32,address,uint256)[])\":{\"details\":\"Performs a set of Pool balance operations, which may be either withdrawals, deposits or updates.

Calls to `swap` cannot be simulated directly, but an equivalent `batchSwap` call can and will yield the exact same result. Each element in the array corresponds to the asset at the same index, and indicates the number of tokens (or ETH) the Vault would take from the sender (if positive) or send to the recipient (if negative). The arguments it receives are the same that an equivalent `batchSwap` call would receive. Unlike `batchSwap`, this function performs no checks on the sender or recipient field in the `funds` struct. This makes it suitable to be called by off-chain applications via eth_call without needing to hold tokens, approve them for the Vault, or even know a user's address. Note that this function is not 'view' (due to implementation details): the client code must explicitly execute eth_call instead of eth_sendTransaction.\"},\"registerPool(uint8)\":{\"details\":\"Registers the caller account as a Pool with a given specialization setting. Returns the Pool's ID, which is used in all Pool-related functions. Pools cannot be deregistered, nor can the Pool's specialization be changed. The caller is expected to be a smart contract that implements either `IGeneralPool` or `IMinimalSwapInfoPool`, depending on the chosen specialization setting. This contract is known as the Pool's contract. Note that the same contract may register itself as multiple Pools with unique Pool IDs, or in other words, multiple Pools may share the same contract. Emits a `PoolRegistered` event.\"},\"registerTokens(bytes32,address[],address[])\":{\"details\":\"Registers `tokens` for the `poolId` Pool. Must be called by the Pool's contract. Pools can only interact with tokens they have registered. Users join a Pool by transferring registered tokens, exit by receiving registered tokens, and can only swap registered tokens. Each token can only be registered once. For Pools with the Two Token specialization, `tokens` must have a length of two, that is, both tokens must be registered in the same `registerTokens` call, and they must be sorted in ascending order. The `tokens` and `assetManagers` arrays must have the same length, and each entry in these indicates the Asset Manager for the corresponding token. Asset Managers can manage a Pool's tokens via `managePoolBalance`, depositing and withdrawing them directly, and can even set their balance to arbitrary amounts. They are therefore expected to be highly secured smart contracts with sound design principles, and the decision to register an Asset Manager should not be made lightly. Pools can choose not to assign an Asset Manager to a given token by passing in the zero address. Once an Asset Manager is set, it cannot be changed except by deregistering the associated token and registering again with a different Asset Manager. Emits a `TokensRegistered` event.\"},\"setPaused(bool)\":{\"details\":\"Safety mechanism to pause most Vault operations in the event of an emergency - typically detection of an error in some part of the system.

In each individual swap, tokens of one kind are sent from the sender to the Pool (this is the 'token in'), and tokens of another kind are sent from the Pool to the recipient in exchange (this is the 'token out').

They need not trust the Pool contracts to do this: all security checks are made by the Vault. The `swap` function executes a single swap, while `batchSwap` can perform multiple swaps in sequence. In each individual swap, tokens of one kind are sent from the sender to the Pool (this is the 'token in'), and tokens of another kind are sent from the Pool to the recipient in exchange (this is the 'token out'). More complex swaps, such as one 'token in' to multiple tokens out can be achieved by batching together individual swaps.",

Each delta corresponds to the asset at the same index in the `assets` array. Swaps are executed sequentially, in the order specified by the `swaps` array. Each array element describes a Pool, the token to be sent to this Pool, the token to receive from it, and an amount that is either `amountIn` or `amountOut` depending on the swap kind. Multihop swaps can be executed by passing an `amount` value of zero for a swap. This will cause the amount in/out of the previous swap to be used as the amount in for the current one. In a 'given in' swap, 'tokenIn' must equal the previous swap's `tokenOut`. For a 'given out' swap, `tokenOut` must equal the previous swap's `tokenIn`. The `assets` array contains the addresses of all assets involved in the swaps. These are either token addresses, or the IAsset sentinel value for ETH (the zero address).

or multiple Pools. In each individual swap, the caller determines either the amount of tokens sent to or received from the Pool, depending on the `kind` value. Returns an array with the net Vault asset balance deltas. Positive amounts represent tokens (or ETH) sent to the Vault, and negative amounts represent tokens (or ETH) sent by the Vault. Each delta corresponds to the asset at the same index in the `assets` array. Swaps are executed sequentially, in the order specified by the `swaps` array. Each array element describes a Pool, the token to be sent to this Pool, the token to receive from it, and an amount that is either `amountIn` or `amountOut` depending on the swap kind. Multihop swaps can be executed by passing an `amount` value of zero for a swap. This will cause the amount in/out of the previous swap to be used as the amount in for the current one. In a 'given in' swap, 'tokenIn' must equal the previous swap's `tokenOut`. For a 'given out' swap, `tokenOut` must equal the previous swap's `tokenIn`. The `assets` array contains the addresses of all assets involved in the swaps. These are either token addresses, or the IAsset sentinel value for ETH (the zero address). Each entry in the `swaps` array specifies tokens in and out by referencing an index in `assets`. Note that Pools never interact with ETH directly: it will be wrapped to or unwrapped from WETH by the Vault. Internal Balance usage, sender, and recipient are determined by the `funds` struct. The `limits` array specifies the minimum or maximum amount of each token the vault is allowed to transfer. `batchSwap` can be used to make a single swap, like `swap` does, but doing so requires more gas than the equivalent `swap` call. Emits `Swap` events.\"},\"changeAuthorizer(address)\":{\"details\":\"Sets a new Authorizer for the Vault. The caller must be allowed by the current Authorizer to do this.

This will trigger custom Pool behavior, which will typically ask for something in return from `sender` - often tokenized Pool shares. The amount of tokens that can be withdrawn is limited by the Pool's `cash` balance (see `getPoolTokenInfo`). If the caller is not `sender`, it must be an authorized relayer for them. The `tokens` and `minAmountsOut` arrays must have the same length, and each entry in these indicates the minimum token amount to receive for each token contract. The amounts to send are decided by the Pool and not the Vault: it just enforces these minimums. If exiting a Pool that holds WETH, it is possible to receive ETH directly: the Vault will do the unwrapping. To enable this mechanism, the IAsset sentinel value (the zero address) must be passed in the `assets` array instead of the WETH address. Note that it is not possible to combine ETH and WETH in the same exit. `assets` must have the same length and order as the array returned by `getPoolTokens`. This prevents issues when interacting with Pools that register and deregister tokens frequently. If receiving ETH however, the array must be sorted *before* replacing the WETH address with the ETH sentinel value (the zero address), which means the final `assets` array might not be sorted. Pools with no registered tokens cannot be exited. If `toInternalBalance` is true, the tokens will be deposited to `recipient`'s Internal Balance. Otherwise, an ERC20 transfer will be performed. Note that ETH cannot be deposited to Internal Balance: attempting to do so will trigger a revert. `minAmountsOut` is the minimum amount of tokens the user expects to get out of the Pool, for each token in the `tokens` array. This array must match the Pool's registered tokens. This causes the Vault to call the `IBasePool.onExitPool` hook on the Pool's contract, where Pools implement their own custom logic. This typically requires additional information from the user (such as the expected number of Pool shares to return).

No action can ever cause a Pool's token `cash`, `managed` or `total` balance to be greater than 2^112 - 1. `lastChangeBlock` is the number of the block in which `token`'s total balance was last modified (via either a join, exit, swap, or Asset Manager update). This value is useful to avoid so-called 'sandwich attacks', for example when developing price oracles.

Calls to `registerTokens` and `deregisterTokens` may change this order. If a Pool only registers tokens once, and these are sorted in ascending order, they will be stored in the same order as passed to `registerTokens`.

To enable this mechanism, the IAsset sentinel value (the zero address) must be passed in the `assets` array instead of the WETH address. Note that it is not possible to combine ETH and WETH in the same join. Any excess ETH will be sent back to the caller (not the sender, which is important for relayers). `assets` must have the same length and order as the array returned by `getPoolTokens`. This prevents issues when interacting with Pools that register and deregister tokens frequently. If sending ETH however, the array must be sorted *before* replacing the WETH address with the ETH sentinel value (the zero address), which means the final `assets` array might not be sorted.

This makes it suitable to be called by off-chain applications via eth_call without needing to hold tokens, approve them for the Vault, or even know a user's address.

This contract is known as the Pool's contract. Note that the same contract may register itself as multiple Pools with unique Pool IDs, or in other words, multiple Pools may share the same contract. Emits a `PoolRegistered` event.\"},\"registerTokens(bytes32,address[],address[])\":{\"details\":\"Registers `tokens` for the `poolId` Pool. Must be called by the Pool's contract. Pools can only interact with tokens they have registered. Users join a Pool by transferring registered tokens, exit by receiving registered tokens, and can only swap registered tokens. Each token can only be registered once. For Pools with the Two Token specialization, `tokens` must have a length of two, that is, both tokens must be registered in the same `registerTokens` call, and they must be sorted in ascending order. The `tokens` and `assetManagers` arrays must have the same length, and each entry in these indicates the Asset Manager for the corresponding token. Asset Managers can manage a Pool's tokens via `managePoolBalance`, depositing and withdrawing them directly, and can even set their balance to arbitrary amounts. They are therefore expected to be highly secured smart contracts with sound design principles, and the decision to register an Asset Manager should not be made lightly. Pools can choose not to assign an Asset Manager to a given token by passing in the zero address. Once an Asset Manager is set, it cannot be changed except by deregistering the associated token and registering again with a different Asset Manager. Emits a `TokensRegistered` event.\"},\"setPaused(bool)\":{\"details\":\"Safety mechanism to pause most Vault operations in the event of an emergency - typically detection of an error in some part of the system. The Vault can only be paused during an initial time period, after which pausing is forever disabled.

This usage of Internal Balance results in greatly reduced gas costs when compared to relying on plain ERC20 transfers, leading to large savings for frequent users.

A single instance of it exists for the entire network, and it is the entity used to interact with Pools by Liquidity Providers who join and exit them, Traders who swap, and Asset Managers who withdraw and deposit tokens. The `Vault`'s source code is split among a number of sub-contracts, with the goal of improving readability and making understanding the system easier. Most sub-contracts have been marked as `abstract` to explicitly indicate that only the full `Vault` is meant to be deployed. Roughly speaking, these are the contents of each sub-contract:  - `AssetManagers`: Pool token Asset Manager registry, and Asset Manager interactions.  - `Fees`: set and compute protocol fees.  - `FlashLoans`: flash loan transfers and fees.  - `PoolBalances`: Pool joins and exits.  - `PoolRegistry`: Pool registration, ID management, and basic queries.  - `PoolTokens`: Pool token registration and registration, and balance queries.  - `Swaps`: Pool swaps.  - `UserBalance`: manage user balances (Internal Balance operations and external balance transfers)  - `VaultAuthorization`: access control, relayers and signature validation. Additionally, the different Pool specializations are handled by the `GeneralPoolsBalance`, `MinimalSwapInfoPoolsBalance` and `TwoTokenPoolsBalance` sub-contracts, which in turn make use of the `BalanceAllocation` library. The most important goal of the `Vault` is to make token swaps use as little gas as possible. This is reflected in a multitude of design decisions, from minor things like the format used to store Pool IDs, to major features such as the different Pool specialization settings. Finally, the large number of tasks carried out by the Vault means its bytecode is very large, close to exceeding the contract size limit imposed by EIP 170 (https://eips.ethereum.org/EIPS/eip-170). Manual tuning of the source code was required to improve code generation and bring the bytecode size below this limit. This includes extensive utilization of `internal` functions (particularly inside modifiers), usage of named return arguments, dedicated storage access methods, dynamic revert reason generation, and usage of inline assembly, to name a few.",

                "details": "Performs a series of swaps with one or multiple Pools. In each individual swap, the caller determines either the amount of tokens sent to or received from the Pool, depending on the `kind` value. Returns an array with the net Vault asset balance deltas. Positive amounts represent tokens (or ETH) sent to the Vault, and negative amounts represent tokens (or ETH) sent by the Vault. Each delta corresponds to the asset at the same index in the `assets` array. Swaps are executed sequentially, in the order specified by the `swaps` array. Each array element describes a Pool, the token to be sent to this Pool, the token to receive from it, and an amount that is either `amountIn` or `amountOut` depending on the swap kind. Multihop swaps can be executed by passing an `amount` value of zero for a swap. This will cause the amount in/out of the previous swap to be used as the amount in for the current one. In a 'given in' swap, 'tokenIn' must equal the previous swap's `tokenOut`. For a 'given out' swap, `tokenOut` must equal the previous swap's `tokenIn`. The `assets` array contains the addresses of all assets involved in the swaps. These are either token addresses, or the IAsset sentinel value for ETH (the zero address). Each entry in the `swaps` array specifies tokens in and out by referencing an index in `assets`. Note that Pools never interact with ETH directly: it will be wrapped to or unwrapped from WETH by the Vault. Internal Balance usage, sender, and recipient are determined by the `funds` struct. The `limits` array specifies the minimum or maximum amount of each token the vault is allowed to transfer. `batchSwap` can be used to make a single swap, like `swap` does, but doing so requires more gas than the equivalent `swap` call. Emits `Swap` events."

This will trigger custom Pool behavior, which will typically ask for something in return from `sender` - often tokenized Pool shares. The amount of tokens that can be withdrawn is limited by the Pool's `cash` balance (see `getPoolTokenInfo`). If the caller is not `sender`, it must be an authorized relayer for them. The `tokens` and `minAmountsOut` arrays must have the same length, and each entry in these indicates the minimum token amount to receive for each token contract. The amounts to send are decided by the Pool and not the Vault: it just enforces these minimums. If exiting a Pool that holds WETH, it is possible to receive ETH directly: the Vault will do the unwrapping. To enable this mechanism, the IAsset sentinel value (the zero address) must be passed in the `assets` array instead of the WETH address. Note that it is not possible to combine ETH and WETH in the same exit. `assets` must have the same length and order as the array returned by `getPoolTokens`. This prevents issues when interacting with Pools that register and deregister tokens frequently. If receiving ETH however, the array must be sorted *before* replacing the WETH address with the ETH sentinel value (the zero address), which means the final `assets` array might not be sorted. Pools with no registered tokens cannot be exited. If `toInternalBalance` is true, the tokens will be deposited to `recipient`'s Internal Balance. Otherwise, an ERC20 transfer will be performed. Note that ETH cannot be deposited to Internal Balance: attempting to do so will trigger a revert. `minAmountsOut` is the minimum amount of tokens the user expects to get out of the Pool, for each token in the `tokens` array. This array must match the Pool's registered tokens. This causes the Vault to call the `IBasePool.onExitPool` hook on the Pool's contract, where Pools implement their own custom logic. This typically requires additional information from the user (such as the expected number of Pool shares to return). This can be encoded in the `userData` argument, which is ignored by the Vault and passed directly to the Pool's contract. Emits a `PoolBalanceChanged` event."

No action can ever cause a Pool's token `cash`, `managed` or `total` balance to be greater than 2^112 - 1. `lastChangeBlock` is the number of the block in which `token`'s total balance was last modified (via either a join, exit, swap, or Asset Manager update). This value is useful to avoid so-called 'sandwich attacks', for example when developing price oracles. A change of zero (e.g. caused by a swap with amount zero) is considered a change for this purpose, and will update `lastChangeBlock`. `assetManager` is the Pool's token Asset Manager."

`Vault` is Balancer V2's core contract. A single instance of it exists for the entire network, and it is the entity used to interact with Pools by Liquidity Providers who join and exit them, Traders who swap, and Asset Managers who withdraw and deposit tokens. The `Vault`'s source code is split among a number of sub-contracts, with the goal of improving readability and making understanding the system easier. Most sub-contracts have been marked as `abstract` to explicitly indicate that only the full `Vault` is meant to be deployed. Roughly speaking, these are the contents of each sub-contract:  - `AssetManagers`: Pool token Asset Manager registry, and Asset Manager interactions.  - `Fees`: set and compute protocol fees.  - `FlashLoans`: flash loan transfers and fees.  - `PoolBalances`: Pool joins and exits.  - `PoolRegistry`: Pool registration, ID management, and basic queries.  - `PoolTokens`: Pool token registration and registration, and balance queries.  - `Swaps`: Pool swaps.  - `UserBalance`: manage user balances (Internal Balance operations and external balance transfers)  - `VaultAuthorization`: access control, relayers and signature validation. Additionally, the different Pool specializations are handled by the `GeneralPoolsBalance`, `MinimalSwapInfoPoolsBalance` and `TwoTokenPoolsBalance` sub-contracts, which in turn make use of the `BalanceAllocation` library. The most important goal of the `Vault` is to make token swaps use as little gas as possible. This is reflected in a multitude of design decisions, from minor things like the format used to store Pool IDs, to major features such as the different Pool specialization settings. Finally, the large number of tasks carried out by the Vault means its bytecode is very large, close to exceeding the contract size limit imposed by EIP 170 (https://eips.ethereum.org/EIPS/eip-170). Manual tuning of the source code was required to improve code generation and bring the bytecode size below this limit. This includes extensive utilization of `internal` functions (particularly inside modifiers), usage of named return arguments, dedicated storage access methods, dynamic revert reason generation, and usage of inline assembly, to name a few.\",\"kind\":\"dev\",\"methods\":{\"WETH()\":{\"details\":\"Returns the Vault's WETH instance.\"},\"batchSwap(uint8,(bytes32,uint256,uint256,uint256,bytes)[],address[],(address,bool,address,bool),int256[],uint256)\":{\"details\":\"Performs a series of swaps with one or multiple Pools. In each individual swap, the caller determines either the amount of tokens sent to or received from the Pool, depending on the `kind` value. Returns an array with the net Vault asset balance deltas. Positive amounts represent tokens (or ETH) sent to the Vault, and negative amounts represent tokens (or ETH) sent by the Vault. Each delta corresponds to the asset at the same index in the `assets` array. Swaps are executed sequentially, in the order specified by the `swaps` array. Each array element describes a Pool, the token to be sent to this Pool, the token to receive from it, and an amount that is either `amountIn` or `amountOut` depending on the swap kind. Multihop swaps can be executed by passing an `amount` value of zero for a swap. This will cause the amount in/out of the previous swap to be used as the amount in for the current one. In a 'given in' swap, 'tokenIn' must equal the previous swap's `tokenOut`. For a 'given out' swap, `tokenOut` must equal the previous swap's `tokenIn`. The `assets` array contains the addresses of all assets involved in the swaps. These are either token addresses, or the IAsset sentinel value for ETH (the zero address). Each entry in the `swaps` array specifies tokens in and out by referencing an index in `assets`. Note that Pools never interact with ETH directly: it will be wrapped to or unwrapped from WETH by the Vault. Internal Balance usage, sender, and recipient are determined by the `funds` struct. The `limits` array specifies the minimum or maximum amount of each token the vault is allowed to transfer. `batchSwap` can be used to make a single swap, like `swap` does, but doing so requires more gas than the equivalent `swap` call. Emits `Swap` events.\"},\"changeAuthorizer(address)\":{\"details\":\"Sets a new Authorizer for the Vault. The caller must be allowed by the current Authorizer to do this.

This will trigger custom Pool behavior, which will typically ask for something in return from `sender` - often tokenized Pool shares. The amount of tokens that can be withdrawn is limited by the Pool's `cash` balance (see `getPoolTokenInfo`). If the caller is not `sender`, it must be an authorized relayer for them. The `tokens` and `minAmountsOut` arrays must have the same length, and each entry in these indicates the minimum token amount to receive for each token contract. The amounts to send are decided by the Pool and not the Vault: it just enforces these minimums. If exiting a Pool that holds WETH, it is possible to receive ETH directly: the Vault will do the unwrapping. To enable this mechanism, the IAsset sentinel value (the zero address) must be passed in the `assets` array instead of the WETH address. Note that it is not possible to combine ETH and WETH in the same exit. `assets` must have the same length and order as the array returned by `getPoolTokens`. This prevents issues when interacting with Pools that register and deregister tokens frequently. If receiving ETH however, the array must be sorted *before* replacing the WETH address with the ETH sentinel value (the zero address), which means the final `assets` array might not be sorted. Pools with no registered tokens cannot be exited. If `toInternalBalance` is true, the tokens will be deposited to `recipient`'s Internal Balance. Otherwise, an ERC20 transfer will be performed. Note that ETH cannot be deposited to Internal Balance: attempting to do so will trigger a revert. `minAmountsOut` is the minimum amount of tokens the user expects to get out of the Pool, for each token in the `tokens` array. This array must match the Pool's registered tokens. This causes the Vault to call the `IBasePool.onExitPool` hook on the Pool's contract, where Pools implement their own custom logic.

No action can ever cause a Pool's token `cash`, `managed` or `total` balance to be greater than 2^112 - 1. `lastChangeBlock` is the number of the block in which `token`'s total balance was last modified (via either a join, exit, swap, or Asset Manager update). This value is useful to avoid so-called 'sandwich attacks', for example when developing price oracles.

Any excess ETH will be sent back to the caller (not the sender, which is important for relayers). `assets` must have the same length and order as the array returned by `getPoolTokens`. This prevents issues when interacting with Pools that register and deregister tokens frequently. If sending ETH however, the array must be sorted *before* replacing the WETH address with the ETH sentinel value (the zero address), which means the final `assets` array might not be sorted. Pools with no registered tokens cannot be joined.

The arguments it receives are the same that an equivalent `batchSwap` call would receive. Unlike `batchSwap`, this function performs no checks on the sender or recipient field in the `funds` struct. This makes it suitable to be called by off-chain applications via eth_call without needing to hold tokens, approve them for the Vault, or even know a user's address.

Asset Managers can manage a Pool's tokens via `managePoolBalance`, depositing and withdrawing them directly, and can even set their balance to arbitrary amounts. They are therefore expected to be highly secured smart contracts with sound design principles, and the decision to register an Asset Manager should not be made lightly.

A single instance of it exists for the entire network, and it is the\\n * entity used to interact with Pools by Liquidity Providers who join and exit them, Traders who swap, and Asset\\n * Managers who withdraw and deposit tokens.\\n *\\n * The `Vault`'s source code is split among a number of sub-contracts, with the goal of improving readability and making\\n * understanding the system easier. Most sub-contracts have been marked as `abstract` to explicitly indicate that only\\n * the full `Vault` is meant to be deployed.\\n *\\n * Roughly speaking, these are the contents of each sub-contract:\\n *\\n *  - `AssetManagers`: Pool token Asset Manager registry, and Asset Manager interactions.\\n *  - `Fees`: set and compute protocol fees.\\n *  - `FlashLoans`: flash loan transfers and fees.\\n *  - `PoolBalances`: Pool joins and exits.\\n *  - `PoolRegistry`: Pool registration, ID management, and basic queries.\\n *  - `PoolTokens`: Pool token registration and registration, and balance queries.\\n *  - `Swaps`: Pool swaps.\\n *  - `UserBalance`: manage user balances (Internal Balance operations and external balance transfers)\\n *  - `VaultAuthorization`: access control, relayers and signature validation.\\n *\\n * Additionally, the different Pool specializations are handled by the `GeneralPoolsBalance`,\\n * `MinimalSwapInfoPoolsBalance` and `TwoTokenPoolsBalance` sub-contracts, which in turn make use of the\\n * `BalanceAllocation` library.\\n *\\n * The most important goal of the `Vault` is to make token swaps use as little gas as possible. This is reflected in a\\n * multitude of design decisions, from minor things like the format used to store Pool IDs, to major features such as\\n * the different Pool specialization settings.\\n *\\n * Finally, the large number of tasks carried out by the Vault means its bytecode is very large, close to exceeding\\n * the contract size limit imposed by EIP 170 (https://eips.ethereum.org/EIPS/eip-170). Manual tuning of the source code\\n * was required to improve code generation and bring the bytecode size below this limit. This includes extensive\\n * utilization of `internal` functions (particularly inside modifiers), usage of named return arguments, dedicated\\n * storage access methods, dynamic revert reason generation, and usage of inline assembly, to name a few.\\n */\\ncontract Vault is VaultAuthorization, FlashLoans, Swaps {\\n    constructor(\\n        IAuthorizer authorizer,\\n        IWETH weth,\\n        uint256 pauseWindowDuration,\\n        uint256 bufferPeriodDuration\\n    ) VaultAuthorization(authorizer) AssetHelpers(weth) TemporarilyPausable(pauseWindowDuration, bufferPeriodDuration) {\\n        // solhint-disable-previous-line no-empty-blocks\\n    }\\n\\n    function setPaused(bool paused) external override nonReentrant authenticate {\\n        _setPaused(paused);\\n    }\\n\\n    // solhint-disable-next-line func-name-mixedcase\\n    function WETH() external view override returns (IWETH) {\\n        return _WETH();\\n    }\\n}\\n\",\"keccak256\":\"0xca8fefb90b4dbc611a7b6685504076b7484974ad0b986cf9b98cae0df4a9035b\",\"license\":\"GPL-3.0-or-later\"},\"src.sol/amm/vault/VaultAuthorization.sol\":{\"content\":\"// SPDX-License-Identifier: GPL-3.0-or-later\\n// This program is free software: you can redistribute it and/or modify\\n// it under the terms of the GNU General Public License as published by\\n// the Free Software Foundation, either version 3 of the License, or\\n// (at your option) any later version.\\n\\n// This program is distributed in the hope that it will be useful,\\n// but WITHOUT ANY WARRANTY; without even the implied warranty of\\n// MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

This is reflected in the different methods available: 'increaseCash'\\n// and 'decreaseCash' for swaps and add/remove liquidity events, and 'cashToManaged' and 'managedToCash' for events\\n// transferring funds to and from the Asset Manager.\\n//\\n// The Vault disallows the Pool's 'cash' from becoming negative.

Each array element describes a Pool, the token to be sent to this Pool, the token to receive from it, and an amount that is either `amountIn` or `amountOut` depending on the swap kind. Multihop swaps can be executed by passing an `amount` value of zero for a swap. This will cause the amount in/out of the previous swap to be used as the amount in for the current one. In a 'given in' swap, 'tokenIn' must equal the previous swap's `tokenOut`. For a 'given out' swap, `tokenOut` must equal the previous swap's `tokenIn`.

In each individual swap, the caller determines either the amount of tokens sent to or received from the Pool, depending on the `kind` value. Returns an array with the net Vault asset balance deltas. Positive amounts represent tokens (or ETH) sent to the Vault, and negative amounts represent tokens (or ETH) sent by the Vault. Each delta corresponds to the asset at the same index in the `assets` array. Swaps are executed sequentially, in the order specified by the `swaps` array. Each array element describes a Pool, the token to be sent to this Pool, the token to receive from it, and an amount that is either `amountIn` or `amountOut` depending on the swap kind. Multihop swaps can be executed by passing an `amount` value of zero for a swap. This will cause the amount in/out of the previous swap to be used as the amount in for the current one. In a 'given in' swap, 'tokenIn' must equal the previous swap's `tokenOut`. For a 'given out' swap, `tokenOut` must equal the previous swap's `tokenIn`. The `assets` array contains the addresses of all assets involved in the swaps. These are either token addresses, or the IAsset sentinel value for ETH (the zero address). Each entry in the `swaps` array specifies tokens in and out by referencing an index in `assets`. Note that Pools never interact with ETH directly: it will be wrapped to or unwrapped from WETH by the Vault. Internal Balance usage, sender, and recipient are determined by the `funds` struct. The `limits` array specifies the minimum or maximum amount of each token the vault is allowed to transfer. `batchSwap` can be used to make a single swap, like `swap` does, but doing so requires more gas than the equivalent `swap` call.

This will trigger custom Pool behavior, which will typically ask for something in return from `sender` - often tokenized Pool shares. The amount of tokens that can be withdrawn is limited by the Pool's `cash` balance (see `getPoolTokenInfo`). If the caller is not `sender`, it must be an authorized relayer for them. The `tokens` and `minAmountsOut` arrays must have the same length, and each entry in these indicates the minimum token amount to receive for each token contract. The amounts to send are decided by the Pool and not the Vault: it just enforces these minimums. If exiting a Pool that holds WETH, it is possible to receive ETH directly: the Vault will do the unwrapping. To enable this mechanism, the IAsset sentinel value (the zero address) must be passed in the `assets` array instead of the WETH address. Note that it is not possible to combine ETH and WETH in the same exit. `assets` must have the same length and order as the array returned by `getPoolTokens`. This prevents issues when interacting with Pools that register and deregister tokens frequently. If receiving ETH however, the array must be sorted *before* replacing the WETH address with the ETH sentinel value (the zero address), which means the final `assets` array might not be sorted. Pools with no registered tokens cannot be exited. If `toInternalBalance` is true, the tokens will be deposited to `recipient`'s Internal Balance. Otherwise, an ERC20 transfer will be performed. Note that ETH cannot be deposited to Internal Balance: attempting to do so will trigger a revert. `minAmountsOut` is the minimum amount of tokens the user expects to get out of the Pool, for each token in the `tokens` array. This array must match the Pool's registered tokens. This causes the Vault to call the `IBasePool.onExitPool` hook on the Pool's contract, where Pools implement their own custom logic.

No action can ever cause a Pool's token `cash`, `managed` or `total` balance to be greater than 2^112 - 1. `lastChangeBlock` is the number of the block in which `token`'s total balance was last modified (via either a join, exit, swap, or Asset Manager update). This value is useful to avoid so-called 'sandwich attacks', for example when developing price oracles.

To enable this mechanism, the IAsset sentinel value (the zero address) must be passed in the `assets` array instead of the WETH address.

Any excess ETH will be sent back to the caller (not the sender, which is important for relayers). `assets` must have the same length and order as the array returned by `getPoolTokens`.

The arguments it receives are the same that an equivalent `batchSwap` call would receive. Unlike `batchSwap`, this function performs no checks on the sender or recipient field in the `funds` struct. This makes it suitable to be called by off-chain applications via eth_call without needing to hold tokens, approve them for the Vault, or even know a user's address.

For Pools with the Two Token specialization, `tokens` must have a length of two, that is, both tokens must be registered in the same `registerTokens` call, and they must be sorted in ascending order. The `tokens` and `assetManagers` arrays must have the same length, and each entry in these indicates the Asset Manager for the corresponding token. Asset Managers can manage a Pool's tokens via `managePoolBalance`, depositing and withdrawing them directly, and can even set their balance to arbitrary amounts. They are therefore expected to be highly secured smart contracts with sound design principles, and the decision to register an Asset Manager should not be made lightly.

Each delta corresponds to the asset at the same index in the `assets` array. Swaps are executed sequentially, in the order specified by the `swaps` array. Each array element describes a Pool, the token to be sent to this Pool, the token to receive from it, and an amount that is either `amountIn` or `amountOut` depending on the swap kind. Multihop swaps can be executed by passing an `amount` value of zero for a swap. This will cause the amount in/out of the previous swap to be used as the amount in for the current one. In a 'given in' swap, 'tokenIn' must equal the previous swap's `tokenOut`. For a 'given out' swap, `tokenOut` must equal the previous swap's `tokenIn`. The `assets` array contains the addresses of all assets involved in the swaps. These are either token addresses, or the IAsset sentinel value for ETH (the zero address).

or multiple Pools. In each individual swap, the caller determines either the amount of tokens sent to or received from the Pool, depending on the `kind` value. Returns an array with the net Vault asset balance deltas. Positive amounts represent tokens (or ETH) sent to the Vault, and negative amounts represent tokens (or ETH) sent by the Vault. Each delta corresponds to the asset at the same index in the `assets` array. Swaps are executed sequentially, in the order specified by the `swaps` array. Each array element describes a Pool, the token to be sent to this Pool, the token to receive from it, and an amount that is either `amountIn` or `amountOut` depending on the swap kind. Multihop swaps can be executed by passing an `amount` value of zero for a swap. This will cause the amount in/out of the previous swap to be used as the amount in for the current one. In a 'given in' swap, 'tokenIn' must equal the previous swap's `tokenOut`. For a 'given out' swap, `tokenOut` must equal the previous swap's `tokenIn`. The `assets` array contains the addresses of all assets involved in the swaps. These are either token addresses, or the IAsset sentinel value for ETH (the zero address). Each entry in the `swaps` array specifies tokens in and out by referencing an index in `assets`. Note that Pools never interact with ETH directly: it will be wrapped to or unwrapped from WETH by the Vault. Internal Balance usage, sender, and recipient are determined by the `funds` struct. The `limits` array specifies the minimum or maximum amount of each token the vault is allowed to transfer. `batchSwap` can be used to make a single swap, like `swap` does, but doing so requires more gas than the equivalent `swap` call.

This will trigger custom Pool behavior, which will typically ask for something in return from `sender` - often tokenized Pool shares. The amount of tokens that can be withdrawn is limited by the Pool's `cash` balance (see `getPoolTokenInfo`). If the caller is not `sender`, it must be an authorized relayer for them. The `tokens` and `minAmountsOut` arrays must have the same length, and each entry in these indicates the minimum token amount to receive for each token contract. The amounts to send are decided by the Pool and not the Vault: it just enforces these minimums. If exiting a Pool that holds WETH, it is possible to receive ETH directly: the Vault will do the unwrapping. To enable this mechanism, the IAsset sentinel value (the zero address) must be passed in the `assets` array instead of the WETH address. Note that it is not possible to combine ETH and WETH in the same exit. `assets` must have the same length and order as the array returned by `getPoolTokens`. This prevents issues when interacting with Pools that register and deregister tokens frequently. If receiving ETH however, the array must be sorted *before* replacing the WETH address with the ETH sentinel value (the zero address), which means the final `assets` array might not be sorted. Pools with no registered tokens cannot be exited. If `toInternalBalance` is true, the tokens will be deposited to `recipient`'s Internal Balance. Otherwise, an ERC20 transfer will be performed. Note that ETH cannot be deposited to Internal Balance: attempting to do so will trigger a revert. `minAmountsOut` is the minimum amount of tokens the user expects to get out of the Pool, for each token in the `tokens` array. This array must match the Pool's registered tokens. This causes the Vault to call the `IBasePool.onExitPool` hook on the Pool's contract, where Pools implement their own custom logic. This typically requires additional information from the user (such as the expected number of Pool shares to return). This can be encoded in the `userData` argument, which is ignored by the Vault and passed directly to the Pool's contract.

No action can ever cause a Pool's token `cash`, `managed` or `total` balance to be greater than 2^112 - 1. `lastChangeBlock` is the number of the block in which `token`'s total balance was last modified (via either a join, exit, swap, or Asset Manager update). This value is useful to avoid so-called 'sandwich attacks', for example when developing price oracles. A change of zero (e.g. caused by a swap with amount zero) is considered a change for this purpose, and will update `lastChangeBlock`. `assetManager` is the Pool's token Asset Manager.\"},\"getPoolTokens(bytes32)\":{\"details\":\"Returns a Pool's registered tokens, the total balance for each, and the latest block when *any* of the tokens' `balances` changed.

Calls to `registerTokens` and `deregisterTokens` may change this order. If a Pool only registers tokens once, and these are sorted in ascending order, they will be stored in the same order as passed to `registerTokens`.

To enable this mechanism, the IAsset sentinel value (the zero address) must be passed in the `assets` array instead of the WETH address.

Any excess ETH will be sent back to the caller (not the sender, which is important for relayers). `assets` must have the same length and order as the array returned by `getPoolTokens`.

This causes the Vault to call the `IBasePool.onJoinPool` hook on the Pool's contract, where Pools implement their own custom logic. This typically requires additional information from the user (such as the expected number of Pool shares). This can be encoded in the `userData` argument, which is ignored by the Vault and passed directly to the Pool's contract, as is `recipient`. Emits a `PoolBalanceChanged` event.\"},\"managePoolBalance((uint8,bytes32,address,uint256)[])\":{\"details\":\"Performs a set of Pool balance operations, which may be either withdrawals, deposits or updates. Pool Balance management features batching, which means a single contract call can be used to perform multiple operations of different kinds, with different Pools and tokens, at once. For each operation, the caller must be registered as the Asset Manager for `token` in `poolId`.\"},\"manageUserBalance((uint8,address,uint256,address,address)[])\":{\"details\":\"Performs a set of user balance operations, which involve Internal Balance (deposit, withdraw or transfer) and plain ERC20 transfers using the Vault's allowance. This last feature is particularly useful for relayers, as it lets integrators reuse a user's Vault allowance. For each operation, if the caller is not `sender`, it must be an authorized relayer for them.\"},\"queryBatchSwap(uint8,(bytes32,uint256,uint256,uint256,bytes)[],address[],(address,bool,address,bool))\":{\"details\":\"Simulates a call to `batchSwap`, returning an array of Vault asset deltas. Calls to `swap` cannot be simulated directly, but an equivalent `batchSwap` call can and will yield the exact same result. Each element in the array corresponds to the asset at the same index, and indicates the number of tokens (or ETH) the Vault would take from the sender (if positive) or send to the recipient (if negative). The arguments it receives are the same that an equivalent `batchSwap` call would receive. Unlike `batchSwap`, this function performs no checks on the sender or recipient field in the `funds` struct. This makes it suitable to be called by off-chain applications via eth_call without needing to hold tokens, approve them for the Vault, or even know a user's address. Note that this function is not 'view' (due to implementation details): the client code must explicitly execute eth_call instead of eth_sendTransaction.\"},\"registerPool(uint8)\":{\"details\":\"Registers the caller account as a Pool with a given specialization setting. Returns the Pool's ID, which is used in all Pool-related functions. Pools cannot be deregistered, nor can the Pool's specialization be changed. The caller is expected to be a smart contract that implements either `IGeneralPool` or `IMinimalSwapInfoPool`, depending on the chosen specialization setting. This contract is known as the Pool's contract. Note that the same contract may register itself as multiple Pools with unique Pool IDs, or in other words, multiple Pools may share the same contract. Emits a `PoolRegistered` event.\"},\"registerTokens(bytes32,address[],address[])\":{\"details\":\"Registers `tokens` for the `poolId` Pool. Must be called by the Pool's contract. Pools can only interact with tokens they have registered. Users join a Pool by transferring registered tokens, exit by receiving registered tokens, and can only swap registered tokens. Each token can only be registered once. For Pools with the Two Token specialization, `tokens` must have a length of two, that is, both tokens must be registered in the same `registerTokens` call, and they must be sorted in ascending order. The `tokens` and `assetManagers` arrays must have the same length, and each entry in these indicates the Asset Manager for the corresponding token. Asset Managers can manage a Pool's tokens via `managePoolBalance`, depositing and withdrawing them directly, and can even set their balance to arbitrary amounts. They are therefore expected to be highly secured smart contracts with sound design principles, and the decision to register an Asset Manager should not be made lightly. Pools can choose not to assign an Asset Manager to a given token by passing in the zero address. Once an Asset Manager is set, it cannot be changed except by deregistering the associated token and registering again with a different Asset Manager. Emits a `TokensRegistered` event.\"},\"setPaused(bool)\":{\"details\":\"Safety mechanism to pause most Vault operations in the event of an emergency - typically detection of an error in some part of the system. The Vault can only be paused during an initial time period, after which pausing is forever disabled. While the contract is paused, the following features are disabled: - depositing and transferring internal balance - transferring external balance (using the Vault's allowance) - swaps - joining Pools - Asset Manager interactions Internal Balance can still be withdrawn, and Pools exited.\"},\"setRelayerApproval(address,address,bool)\":{\"details\":\"Allows `relayer` to act as a relayer for `sender` if `approved` is true, and disallows it otherwise.

Positive amounts represent tokens (or ETH) sent to the Vault, and negative amounts represent tokens (or ETH) sent by the Vault. Each delta corresponds to the asset at the same index in the `assets` array. Swaps are executed sequentially, in the order specified by the `swaps` array. Each array element describes a Pool, the token to be sent to this Pool, the token to receive from it, and an amount that is either `amountIn` or `amountOut` depending on the swap kind. Multihop swaps can be executed by passing an `amount` value of zero for a swap. This will cause the amount in/out of the previous swap to be used as the amount in for the current one. In a 'given in' swap, 'tokenIn' must equal the previous swap's `tokenOut`. For a 'given out' swap, `tokenOut` must equal the previous swap's `tokenIn`. The `assets` array contains the addresses of all assets involved in the swaps. These are either token addresses, or the IAsset sentinel value for ETH (the zero address). Each entry in the `swaps` array specifies tokens in and out by referencing an index in `assets`. Note that Pools never interact with ETH directly: it will be wrapped to or unwrapped from WETH by the Vault. Internal Balance usage, sender, and recipient are determined by the `funds` struct. The `limits` array specifies the minimum or maximum amount of each token the vault is allowed to transfer. `batchSwap` can be used to make a single swap, like `swap` does, but doing so requires more gas than the equivalent `swap` call.

Positive amounts represent tokens (or ETH) sent to the Vault, and negative amounts represent tokens (or ETH) sent by the Vault. Each delta corresponds to the asset at the same index in the `assets` array. Swaps are executed sequentially, in the order specified by the `swaps` array. Each array element describes a Pool, the token to be sent to this Pool, the token to receive from it, and an amount that is either `amountIn` or `amountOut` depending on the swap kind. Multihop swaps can be executed by passing an `amount` value of zero for a swap. This will cause the amount in/out of the previous swap to be used as the amount in for the current one. In a 'given in' swap, 'tokenIn' must equal the previous swap's `tokenOut`. For a 'given out' swap, `tokenOut` must equal the previous swap's `tokenIn`. The `assets` array contains the addresses of all assets involved in the swaps. These are either token addresses, or the IAsset sentinel value for ETH (the zero address). Each entry in the `swaps` array specifies tokens in and out by referencing an index in `assets`. Note that Pools never interact with ETH directly: it will be wrapped to or unwrapped from WETH by the Vault. Internal Balance usage, sender, and recipient are determined by the `funds` struct. The `limits` array specifies the minimum or maximum amount of each token the vault is allowed to transfer. `batchSwap` can be used to make a single swap, like `swap` does, but doing so requires more gas than the equivalent `swap` call.

The `tokens` and `minAmountsOut` arrays must have the same length, and each entry in these indicates the minimum token amount to receive for each token contract. The amounts to send are decided by the Pool and not the Vault: it just enforces these minimums. If exiting a Pool that holds WETH, it is possible to receive ETH directly: the Vault will do the unwrapping. To enable this mechanism, the IAsset sentinel value (the zero address) must be passed in the `assets` array instead of the WETH address. Note that it is not possible to combine ETH and WETH in the same exit. `assets` must have the same length and order as the array returned by `getPoolTokens`.

Pools with no registered tokens cannot be exited. If `toInternalBalance` is true, the tokens will be deposited to `recipient`'s Internal Balance. Otherwise, an ERC20 transfer will be performed. Note that ETH cannot be deposited to Internal Balance: attempting to do so will trigger a revert. `minAmountsOut` is the minimum amount of tokens the user expects to get out of the Pool, for each token in the `tokens` array. This array must match the Pool's registered tokens. This causes the Vault to call the `IBasePool.onExitPool` hook on the Pool's contract, where Pools implement their own custom logic.

This value is useful to avoid so-called 'sandwich attacks', for example when developing price oracles.

Any excess ETH will be sent back to the caller (not the sender, which is important for relayers). `assets` must have the same length and order as the array returned by `getPoolTokens`.

Each delta corresponds to the asset at the same index in the `assets` array. Swaps are executed sequentially, in the order specified by the `swaps` array. Each array element describes a Pool, the token to be sent to this Pool, the token to receive from it, and an amount that is either `amountIn` or `amountOut` depending on the swap kind. Multihop swaps can be executed by passing an `amount` value of zero for a swap. This will cause the amount in/out of the previous swap to be used as the amount in for the current one. In a 'given in' swap, 'tokenIn' must equal the previous swap's `tokenOut`. For a 'given out' swap, `tokenOut` must equal the previous swap's `tokenIn`. The `assets` array contains the addresses of all assets involved in the swaps. These are either token addresses, or the IAsset sentinel value for ETH (the zero address). Each entry in the `swaps` array specifies tokens in and out by referencing an index in `assets`. Note that Pools never interact with ETH directly: it will be wrapped to or unwrapped from WETH by the Vault. Internal Balance usage, sender, and recipient are determined by the `funds` struct. The `limits` array specifies the minimum or maximum amount of each token the vault is allowed to transfer. `batchSwap` can be used to make a single swap, like `swap` does, but doing so requires more gas than the equivalent `swap` call.

This will trigger custom Pool behavior, which will typically ask for something in return from `sender` - often tokenized Pool shares. The amount of tokens that can be withdrawn is limited by the Pool's `cash` balance (see `getPoolTokenInfo`). If the caller is not `sender`, it must be an authorized relayer for them. The `tokens` and `minAmountsOut` arrays must have the same length, and each entry in these indicates the minimum token amount to receive for each token contract. The amounts to send are decided by the Pool and not the Vault: it just enforces these minimums. If exiting a Pool that holds WETH, it is possible to receive ETH directly: the Vault will do the unwrapping. To enable this mechanism, the IAsset sentinel value (the zero address) must be passed in the `assets` array instead of the WETH address. Note that it is not possible to combine ETH and WETH in the same exit. `assets` must have the same length and order as the array returned by `getPoolTokens`. This prevents issues when interacting with Pools that register and deregister tokens frequently. If receiving ETH however, the array must be sorted *before* replacing the WETH address with the ETH sentinel value (the zero address), which means the final `assets` array might not be sorted. Pools with no registered tokens cannot be exited. If `toInternalBalance` is true, the tokens will be deposited to `recipient`'s Internal Balance. Otherwise, an ERC20 transfer will be performed. Note that ETH cannot be deposited to Internal Balance: attempting to do so will trigger a revert. `minAmountsOut` is the minimum amount of tokens the user expects to get out of the Pool, for each token in the `tokens` array. This array must match the Pool's registered tokens. This causes the Vault to call the `IBasePool.onExitPool` hook on the Pool's contract, where Pools implement their own custom logic. This typically requires additional information from the user (such as the expected number of Pool shares to return). This can be encoded in the `userData` argument, which is ignored by the Vault and passed directly to the Pool's contract. Emits a `PoolBalanceChanged` event."

This will trigger custom Pool behavior, which will typically grant something in return to `recipient` - often tokenized Pool shares. If the caller is not `sender`, it must be an authorized relayer for them. The `assets` and `maxAmountsIn` arrays must have the same length, and each entry indicates the maximum amount to send for each asset. The amounts to send are decided by the Pool and not the Vault: it just enforces these maximums. If joining a Pool that holds WETH, it is possible to send ETH directly: the Vault will do the wrapping. To enable this mechanism, the IAsset sentinel value (the zero address) must be passed in the `assets` array instead of the WETH address. Note that it is not possible to combine ETH and WETH in the same join. Any excess ETH will be sent back to the caller (not the sender, which is important for relayers). `assets` must have the same length and order as the array returned by `getPoolTokens`. This prevents issues when interacting with Pools that register and deregister tokens frequently. If sending ETH however, the array must be sorted *before* replacing the WETH address with the ETH sentinel value (the zero address), which means the final `assets` array might not be sorted. Pools with no registered tokens cannot be joined. If `fromInternalBalance` is true, the caller's Internal Balance will be preferred: ERC20 transfers will only be made for the difference between the requested amount and Internal Balance (if any). Note that ETH cannot be withdrawn from Internal Balance: attempting to do so will trigger a revert. This causes the Vault to call the `IBasePool.onJoinPool` hook on the Pool's contract, where Pools implement their own custom logic. This typically requires additional information from the user (such as the expected number of Pool shares). This can be encoded in the `userData` argument, which is ignored by the Vault and passed directly to the Pool's contract, as is `recipient`. Emits a `PoolBalanceChanged` event."

The arguments it receives are the same that an equivalent `batchSwap` call would receive. Unlike `batchSwap`, this function performs no checks on the sender or recipient field in the `funds` struct. This makes it suitable to be called by off-chain applications via eth_call without needing to hold tokens, approve them for the Vault, or even know a user's address.

Users join a Pool by transferring registered tokens, exit by receiving registered tokens, and can only swap registered tokens. Each token can only be registered once. For Pools with the Two Token specialization, `tokens` must have a length of two, that is, both tokens must be registered in the same `registerTokens` call, and they must be sorted in ascending order. The `tokens` and `assetManagers` arrays must have the same length, and each entry in these indicates the Asset Manager for the corresponding token. Asset Managers can manage a Pool's tokens via `managePoolBalance`, depositing and withdrawing them directly, and can even set their balance to arbitrary amounts. They are therefore expected to be highly secured smart contracts with sound design principles, and the decision to register an Asset Manager should not be made lightly. Pools can choose not to assign an Asset Manager to a given token by passing in the zero address. Once an Asset Manager is set, it cannot be changed except by deregistering the associated token and registering again with a different Asset Manager. Emits a `TokensRegistered` event."

The `assets` array contains the addresses of all assets involved in the swaps. These are either token addresses, or the IAsset sentinel value for ETH (the zero address). Each entry in the `swaps` array specifies tokens in and out by referencing an index in `assets`. Note that Pools never interact with ETH directly: it will be wrapped to or unwrapped from WETH by the Vault. Internal Balance usage, sender, and recipient are determined by the `funds` struct. The `limits` array specifies the minimum or maximum amount of each token the vault is allowed to transfer. `batchSwap` can be used to make a single swap, like `swap` does, but doing so requires more gas than the equivalent `swap` call. Emits `Swap` events.\"},\"changeAuthorizer(address)\":{\"details\":\"Sets a new Authorizer for the Vault. The caller must be allowed by the current Authorizer to do this.

This will trigger custom Pool behavior, which will typically ask for something in return from `sender` - often tokenized Pool shares. The amount of tokens that can be withdrawn is limited by the Pool's `cash` balance (see `getPoolTokenInfo`). If the caller is not `sender`, it must be an authorized relayer for them. The `tokens` and `minAmountsOut` arrays must have the same length, and each entry in these indicates the minimum token amount to receive for each token contract. The amounts to send are decided by the Pool and not the Vault: it just enforces these minimums. If exiting a Pool that holds WETH, it is possible to receive ETH directly: the Vault will do the unwrapping. To enable this mechanism, the IAsset sentinel value (the zero address) must be passed in the `assets` array instead of the WETH address. Note that it is not possible to combine ETH and WETH in the same exit. `assets` must have the same length and order as the array returned by `getPoolTokens`. This prevents issues when interacting with Pools that register and deregister tokens frequently. If receiving ETH however, the array must be sorted *before* replacing the WETH address with the ETH sentinel value (the zero address), which means the final `assets` array might not be sorted. Pools with no registered tokens cannot be exited. If `toInternalBalance` is true, the tokens will be deposited to `recipient`'s Internal Balance. Otherwise, an ERC20 transfer will be performed. Note that ETH cannot be deposited to Internal Balance: attempting to do so will trigger a revert. `minAmountsOut` is the minimum amount of tokens the user expects to get out of the Pool, for each token in the `tokens` array. This array must match the Pool's registered tokens. This causes the Vault to call the `IBasePool.onExitPool` hook on the Pool's contract, where Pools implement their own custom logic. This typically requires additional information from the user (such as the expected number of Pool shares to return).

No action can ever cause a Pool's token `cash`, `managed` or `total` balance to be greater than 2^112 - 1. `lastChangeBlock` is the number of the block in which `token`'s total balance was last modified (via either a join, exit, swap, or Asset Manager update). This value is useful to avoid so-called 'sandwich attacks', for example when developing price oracles.

The arguments it receives are the same that an equivalent `batchSwap` call would receive. Unlike `batchSwap`, this function performs no checks on the sender or recipient field in the `funds` struct. This makes it suitable to be called by off-chain applications via eth_call without needing to hold tokens, approve them for the Vault, or even know a user's address.

Asset Managers can manage a Pool's tokens via `managePoolBalance`, depositing and withdrawing them directly, and can even set their balance to arbitrary amounts. They are therefore expected to be highly secured smart contracts with sound design principles, and the decision to register an Asset Manager should not be made lightly.

Can be\n used as an emergency switch in case a security vulnerability or threat is identified.\n The contract can only be paused during the Pause Window, a period that starts at deployment. It can also be\n unpaused and repaused any number of times during this period. This is intended to serve as a safety measure: it lets\n system managers react quickly to potentially dangerous situations, knowing that this action is reversible if careful\n analysis later determines there was a false alarm.\n If the contract is paused when the Pause Window finishes, it will remain in the paused state through an additional\n Buffer Period, after which it will be automatically unpaused forever. This is to ensure there is always enough time\n to react to an emergency, even if the threat is discovered shortly before the Pause Window expires.\n Note that since the contract can only be paused within the Pause Window, unpausing during the Buffer Period is\n irreversible."

These should be exposed\n in the external API and be unique. The best way to achieve this is by\n using `public constant` hash digests:\n ```\n bytes32 public constant MY_ROLE = keccak256(\"MY_ROLE\");\n ```\n Roles can be used to represent a set of permissions. To restrict access to a\n function call, use {hasRole}:\n ```\n function foo() public {\n     require(hasRole(MY_ROLE, msg.sender));\n     ...\n }\n ```\n Roles can be granted and revoked dynamically via the {grantRole} and\n {revokeRole} functions. Each role has an associated admin role, and only\n accounts that have a role's admin role can call {grantRole} and {revokeRole}.\n By default, the admin role for all roles is `DEFAULT_ADMIN_ROLE`, which means\n that only accounts with this role will be able to grant or revoke other\n roles. More complex role relationships can be created by using\n {_setRoleAdmin}.\n WARNING: The `DEFAULT_ADMIN_ROLE` is also its own admin: it has permission to\n grant and revoke this role. Extra precautions should be taken to secure\n accounts that have been granted it."

This means\n that a supply mechanism has to be added in a derived contract using {_mint}.\n For a generic mechanism see {ERC20PresetMinterPauser}.\n TIP: For a detailed writeup see our guide\n https://forum.zeppelin.solutions/t/how-to-implement-erc20-supply-mechanisms/226[How\n to implement supply mechanisms].\n We have followed general OpenZeppelin guidelines: functions revert instead\n of returning `false` on failure. This behavior is nonetheless conventional\n and does not conflict with the expectations of ERC20 applications.\n Additionally, an {Approval} event is emitted on calls to {transferFrom}.\n This allows applications to reconstruct the allowance for all accounts just\n by listening to said events. Other implementations of the EIP may not emit\n these events, as it isn't required by the specification.\n Finally, the non-standard {decreaseAllowance} and {increaseAllowance}\n functions have been added to mitigate the well-known issues around setting\n allowances. See {IERC20-approve}."

This can be worked around by making\n those functions `private`, and then adding `external` `nonReentrant` entry\n points to them.\n TIP: If you would like to learn more about reentrancy and alternative ways\n to protect against it, check out our blog post\n https://blog.openzeppelin.com/reentrancy-after-istanbul/[Reentrancy After Istanbul]."

This can\n easily result in undesired exploitation or bugs, since developers usually\n assume that overflows raise errors. `SafeCast` restores this intuition by\n reverting the transaction when such an operation overflows.\n Using this library instead of the unchecked operations eliminates an entire\n class of bugs, so it's recommended to use it always.\n Can be combined with {SafeMath} and {SignedSafeMath} to extend it to smaller types, by performing\n all math on `uint256` and `int256` and then downcasting."

They are passed through so that\n derived contracts can use them via the `_addSwapFeeAmount` and `_subtractSwapFeeAmount` functions, and the\n `whenNotPaused` modifier.\n No admin permissions are checked here: instead, this contract delegates that to the Vault's own Authorizer.\n Because this contract doesn't implement the swap hooks, derived contracts should generally inherit from\n BaseGeneralPool or BaseMinimalSwapInfoPool. Otherwise, subclasses must inherit from the corresponding interfaces\n and implement the swap callbacks themselves."

This can be done safely.\n BPT will be burnt from `sender`.\n The Pool will grant tokens to `recipient`.

They need not trust the Pool\n contracts to do this: all security checks are made by the Vault.\n The `swap` function executes a single swap, while `batchSwap` can perform multiple swaps in sequence.\n In each individual swap, tokens of one kind are sent from the sender to the Pool (this is the 'token in'),\n and tokens of another kind are sent from the Pool to the recipient in exchange (this is the 'token out').\n More complex swaps, such as one 'token in' to multiple tokens out can be achieved by batching together\n individual swaps."

It can also be used as a source of tokens when joining Pools, as a destination\n when exiting them, and as either when performing swaps. This usage of Internal Balance results in greatly reduced\n gas costs when compared to relying on plain ERC20 transfers, leading to large savings for frequent users.\n Internal Balance management features batching, which means a single contract call can be used to perform multiple\n operations of different kinds, with different senders and recipients, at once."

                "text": " @dev The `Vault` is Balancer V2's core contract. A single instance of it exists for the entire network, and it is the\n entity used to interact with Pools by Liquidity Providers who join and exit them, Traders who swap, and Asset\n Managers who withdraw and deposit tokens.\n The `Vault`'s source code is split among a number of sub-contracts, with the goal of improving readability and making\n understanding the system easier. Most sub-contracts have been marked as `abstract` to explicitly indicate that only\n the full `Vault` is meant to be deployed.\n Roughly speaking, these are the contents of each sub-contract:\n  - `AssetManagers`: Pool token Asset Manager registry, and Asset Manager interactions.\n  - `Fees`: set and compute protocol fees.\n  - `FlashLoans`: flash loan transfers and fees.\n  - `PoolBalances`: Pool joins and exits.\n  - `PoolRegistry`: Pool registration, ID management, and basic queries.\n  - `PoolTokens`: Pool token registration and registration, and balance queries.\n  - `Swaps`: Pool swaps.\n  - `UserBalance`: manage user balances (Internal Balance operations and external balance transfers)\n  - `VaultAuthorization`: access control, relayers and signature validation.\n Additionally, the different Pool specializations are handled by the `GeneralPoolsBalance`,\n `MinimalSwapInfoPoolsBalance` and `TwoTokenPoolsBalance` sub-contracts, which in turn make use of the\n `BalanceAllocation` library.\n The most important goal of the `Vault` is to make token swaps use as little gas as possible. This is reflected in a\n multitude of design decisions, from minor things like the format used to store Pool IDs, to major features such as\n the different Pool specialization settings.\n Finally, the large number of tasks carried out by the Vault means its bytecode is very large, close to exceeding\n the contract size limit imposed by EIP 170 (https://eips.ethereum.org/EIPS/eip-170). Manual tuning of the source code\n was required to improve code generation and bring the bytecode size below this limit. This includes extensive\n utilization of `internal` functions (particularly inside modifiers), usage of named return arguments, dedicated\n storage access methods, dynamic revert reason generation, and usage of inline assembly, to name a few."

The Vault will then take tokens from the Pool's balances and send them to `recipient`,\n as well as collect the reported amount in protocol fees, which the Pool should calculate based on\n `protocolSwapFeePercentage`.\n Protocol fees are charged on exit events to guarantee that users exiting the Pool have paid their share.\n `sender` is the account performing the exit (typically the pool shareholder), and `recipient` is the account\n to which the Vault will send the proceeds. `currentBalances` contains the total token balances for each token\n the Pool registered in the Vault, in the same order that `IVault.getPoolTokens` would return.\n `lastChangeBlock` is the last block in which *any* of the Pool's registered tokens last changed its total\n balance.\n `userData` contains any pool-specific instructions needed to perform the calculations, such as the type of\n exit (e.g., proportional given an amount of pool shares, single-asset, multi-asset, etc.)\n Contracts implementing this function should check that the caller is indeed the Vault before performing any\n state-changing operations, such as burning pool shares."

For Pools with the Two Token specialization, `tokens` must have a length\n of two, that is, both tokens must be registered in the same `registerTokens` call, and they must be sorted in\n ascending order.\n The `tokens` and `assetManagers` arrays must have the same length, and each entry in these indicates the Asset\n Manager for the corresponding token. Asset Managers can manage a Pool's tokens via `managePoolBalance`,\n depositing and withdrawing them directly, and can even set their balance to arbitrary amounts. They are therefore\n expected to be highly secured smart contracts with sound design principles, and the decision to register an\n Asset Manager should not be made lightly.\n Pools can choose not to assign an Asset Manager to a given token by passing in the zero address. Once an Asset\n Manager is set, it cannot be changed except by deregistering the associated token and registering again with a\n different Asset Manager.\n Emits a `TokensRegistered` event."

This will\n trigger custom Pool behavior, which will typically grant something in return to `recipient` - often tokenized\n Pool shares.\n If the caller is not `sender`, it must be an authorized relayer for them.\n The `assets` and `maxAmountsIn` arrays must have the same length, and each entry indicates the maximum amount\n to send for each asset. The amounts to send are decided by the Pool and not the Vault: it just enforces\n these maximums.\n If joining a Pool that holds WETH, it is possible to send ETH directly: the Vault will do the wrapping. To enable\n this mechanism, the IAsset sentinel value (the zero address) must be passed in the `assets` array instead of the\n WETH address. Note that it is not possible to combine ETH and WETH in the same join. Any excess ETH will be sent\n back to the caller (not the sender, which is important for relayers).\n `assets` must have the same length and order as the array returned by `getPoolTokens`. This prevents issues when\n interacting with Pools that register and deregister tokens frequently. If sending ETH however, the array must be\n sorted *before* replacing the WETH address with the ETH sentinel value (the zero address), which means the final\n `assets` array might not be sorted. Pools with no registered tokens cannot be joined.\n If `fromInternalBalance` is true, the caller's Internal Balance will be preferred: ERC20 transfers will only\n be made for the difference between the requested amount and Internal Balance (if any). Note that ETH cannot be\n withdrawn from Internal Balance: attempting to do so will trigger a revert.\n This causes the Vault to call the `IBasePool.onJoinPool` hook on the Pool's contract, where Pools implement\n their own custom logic. This typically requires additional information from the user (such as the expected number\n of Pool shares). This can be encoded in the `userData` argument, which is ignored by the Vault and passed\n directly to the Pool's contract, as is `recipient`.\n Emits a `PoolBalanceChanged` event."

This will\n trigger custom Pool behavior, which will typically ask for something in return from `sender` - often tokenized\n Pool shares. The amount of tokens that can be withdrawn is limited by the Pool's `cash` balance (see\n `getPoolTokenInfo`).\n If the caller is not `sender`, it must be an authorized relayer for them.\n The `tokens` and `minAmountsOut` arrays must have the same length, and each entry in these indicates the minimum\n token amount to receive for each token contract. The amounts to send are decided by the Pool and not the Vault:\n it just enforces these minimums.\n If exiting a Pool that holds WETH, it is possible to receive ETH directly: the Vault will do the unwrapping. To\n enable this mechanism, the IAsset sentinel value (the zero address) must be passed in the `assets` array instead\n of the WETH address. Note that it is not possible to combine ETH and WETH in the same exit.\n `assets` must have the same length and order as the array returned by `getPoolTokens`. This prevents issues when\n interacting with Pools that register and deregister tokens frequently. If receiving ETH however, the array must\n be sorted *before* replacing the WETH address with the ETH sentinel value (the zero address), which means the\n final `assets` array might not be sorted. Pools with no registered tokens cannot be exited.\n If `toInternalBalance` is true, the tokens will be deposited to `recipient`'s Internal Balance. Otherwise,\n an ERC20 transfer will be performed. Note that ETH cannot be deposited to Internal Balance: attempting to\n do so will trigger a revert.\n `minAmountsOut` is the minimum amount of tokens the user expects to get out of the Pool, for each token in the\n `tokens` array. This array must match the Pool's registered tokens.\n This causes the Vault to call the `IBasePool.onExitPool` hook on the Pool's contract, where Pools implement\n their own custom logic. This typically requires additional information from the user (such as the expected number\n of Pool shares to return). This can be encoded in the `userData` argument, which is ignored by the Vault and\n passed directly to the Pool's contract.\n Emits a `PoolBalanceChanged` event."

In each individual swap, the caller determines either\n the amount of tokens sent to or received from the Pool, depending on the `kind` value.\n Returns an array with the net Vault asset balance deltas. Positive amounts represent tokens (or ETH) sent to the\n Vault, and negative amounts represent tokens (or ETH) sent by the Vault. Each delta corresponds to the asset at\n the same index in the `assets` array.\n Swaps are executed sequentially, in the order specified by the `swaps` array. Each array element describes a\n Pool, the token to be sent to this Pool, the token to receive from it, and an amount that is either `amountIn` or\n `amountOut` depending on the swap kind.\n Multihop swaps can be executed by passing an `amount` value of zero for a swap. This will cause the amount in/out\n of the previous swap to be used as the amount in for the current one. In a 'given in' swap, 'tokenIn' must equal\n the previous swap's `tokenOut`. For a 'given out' swap, `tokenOut` must equal the previous swap's `tokenIn`.\n The `assets` array contains the addresses of all assets involved in the swaps. These are either token addresses,\n or the IAsset sentinel value for ETH (the zero address). Each entry in the `swaps` array specifies tokens in and\n out by referencing an index in `assets`. Note that Pools never interact with ETH directly: it will be wrapped to\n or unwrapped from WETH by the Vault.\n Internal Balance usage, sender, and recipient are determined by the `funds` struct. The `limits` array specifies\n the minimum or maximum amount of each token the vault is allowed to transfer.\n `batchSwap` can be used to make a single swap, like `swap` does, but doing so requires more gas than the\n equivalent `swap` call.\n Emits `Swap` events."

Calls to `swap` cannot be\n simulated directly, but an equivalent `batchSwap` call can and will yield the exact same result.\n Each element in the array corresponds to the asset at the same index, and indicates the number of tokens (or ETH)\n the Vault would take from the sender (if positive) or send to the recipient (if negative). The arguments it\n receives are the same that an equivalent `batchSwap` call would receive.\n Unlike `batchSwap`, this function performs no checks on the sender or recipient field in the `funds` struct.\n This makes it suitable to be called by off-chain applications via eth_call without needing to hold tokens,\n approve them for the Vault, or even know a user's address.\n Note that this function is not 'view' (due to implementation details): the client code must explicitly execute\n eth_call instead of eth_sendTransaction."
