# Changelog

## 2.0.0

### Breaking

- **`Rain.buildApprovalTx` requires an explicit `amount`** — The previous default of `ethers.MaxUint256` has been removed. Infinite approvals defeat spending-cap enforcement in ERC-4337 session-key policies (e.g. Alchemy Modular Account v2's `erc20-token-transfer` permission), forcing integrators onto weaker `functions-on-contract` permissions with no spend tracking. Callers must now pass the exact required amount per call. `ApproveTxParams.amount` is now a required `bigint`; values `<= 0n` are rejected. Internal callers in `buildCreateMarketTx` and `buildDisputeTx`/`buildAppealTx` now pass the exact required amount automatically.

---

## 1.1.2

### Fixes

- **Lazy-load account-kit deps** — `@account-kit/infra`, `@account-kit/wallet-client`, and `@alchemy/aa-core` are now dynamically imported inside `RainAA.connect()` instead of at the top level. Server-side consumers who only need the stateless `Rain` class can now import the SDK without installing browser-only account-kit dependencies.
