### Initialising wallet for SDK

#### Ethereum

```typescript
import Web3ProviderEngine from "web3-provider-engine"
import Wallet from "ethereumjs-wallet"
import { TestSubprovider } from "@rarible/test-provider"
// @ts-ignore
import RpcSubprovider from "web3-provider-engine/subproviders/rpc"
import { EthereumWallet } from "@rarible/sdk-wallet"
import { ethers } from "ethers"
import { EthersEthereum } from "@rarible/ethers-ethereum"
import Web3 from "web3"
import { Web3Ethereum } from "@rarible/web3-ethereum"
import { createRaribleSdk } from "@rarible/sdk"

const privateKey = "YOUR_ETHEREUM_PRIVATE_KEY"

// init with ethers
const raribleEthers = new ethers.providers.JsonRpcProvider(process.env["ETHEREUM_RPC_URL"])
const raribleProvider = new EthersEthereum(new ethers.Wallet(privateKey, raribleEthers))
const raribleWallet = new EthereumWallet(raribleProvider)
const raribleSdkWithEthers = createRaribleSdk(raribleWallet, "staging")

// init with web3
const provider = new Web3ProviderEngine({ pollingInterval: 100 })
const sansPrefixedPrivateKey = privateKey.startsWith("0x") ? privateKey.substring(2) : privateKey
const wallet = new Wallet(Buffer.from(sansPrefixedPrivateKey, "hex"))
provider.addProvider(new TestSubprovider(wallet, { networkId: config.networkId, chainId: config.networkId }))
provider.addProvider(new RpcSubprovider({ rpcUrl: config.rpcUrl }))
provider.start()
const web3 = new Web3(provider)
const web3Ethereum = new Web3Ethereum({ web3 })
const raribleSdkWallet = new EthereumWallet(web3Ethereum)
const raribleSdkWithWeb3 = createRaribleSdk(raribleSdkWallet, "dev")
```

#### Polygon

For Polygon you should use "ethers", same as for regular ethereum setup.
Or "web3js" with "estimate" from [@rarible/estimate-middleware](https://www.npmjs.com/package/@rarible/estimate-middleware)
```typescript
import { EthereumWallet } from "@rarible/sdk-wallet"
import HDWalletProvider from "@truffle/hdwallet-provider"
import Web3 from "web3"
import { Web3Ethereum } from "@rarible/web3-ethereum"
import { estimate } from "@rarible/estimate-middleware"

// Setup with web3js //
//configure rpc provider
const provider = new HDWalletProvider(privateKey, process.env["ETHEREUM_RPC_URL"])

// create web3 object with estimate middleware for EIP1559 transactions
const providerWithEstimateMiddleware = estimate(provider, {threshold: 1.1, estimation: process.env["ETHEREUM_RPC_URL"]})
const web3 = new Web3(providerWithEstimateMiddleware)

const web3Ethereum = new Web3Ethereum({ web3 })
const raribleSdkWallet = new EthereumWallet(web3Ethereum)
const raribleSdkWithWeb3 = createRaribleSdk(raribleSdkWallet, "staging")

// Setup with ethers (same as for ethereum)
const raribleEthers = new ethers.providers.JsonRpcProvider(process.env["ETHEREUM_RPC_URL"])
const raribleProvider = new EthersEthereum(new ethers.Wallet(privateKey, raribleEthers))
const raribleWallet = new EthereumWallet(raribleProvider)
const raribleSdkWithEthers = createRaribleSdk(raribleWallet, "staging")

```

#### Solana
```typescript
import { SolanaKeypairWallet } from "@rarible/solana-wallet"
import { SolanaWallet } from "@rarible/sdk-wallet"
import { createRaribleSdk } from "@rarible/sdk"

const privateKey = "YOUR_SOLANA_PRIVATE_KEY"

const keypairWallet = SolanaKeypairWallet.createFrom(privateKey)
const raribleSdkWallet = new SolanaWallet(keypairWallet)
const raribleSdk = createRaribleSdk(raribleSdkWallet, "dev")
```

#### Tezos
```typescript
import { TezosWallet } from "@rarible/sdk-wallet"
import { in_memory_provider } from "@rarible/tezos-sdk/dist/providers/in_memory/in_memory_provider"
import { createRaribleSdk } from "@rarible/sdk"

const walletEdsk = "edskRqrEPcFetuV7xDMMFXHLMPbsTawXZjH9yrEz4RBqH1D6" +
"H8CeZTTtjGA3ynjTqD8Sgmksi7p5g3u5KUEVqX2EWrRnq5Bymj"
const provider = in_memory_provider(
    walletEdsk,
    "https://test-tezos-node.rarible.org"
)
const wallet = new TezosWallet(provider)
const sdk = createRaribleSdk(wallet, "testnet")
```
#### Flow

```typescript
import { FlowWallet } from "@rarible/sdk-wallet"
import * as fcl from "@onflow/fcl"
import { createFlowAuth } from "@rarible/flow-test-common"
import { createRaribleSdk } from "@rarible/sdk"

export function initFlowWallet(accountAddress: string, privateKey: string) {
	const flowAuth = createFlowAuth(fcl, "testnet", accountAddress, privateKey)
	const raribleFlowWallet = new FlowWallet(fcl, flowAuth)
	const raribleSdk = createRaribleSdk(wallet, "testnet")
}
```
