v1.1.0 - 2025-07-11

Base

BaseAsyncSwap: Add interface IHookEvents to the contract in order to standardize event emissions in hooks. Add _calculateSwapFee function to calculate the swap fee amount in an asynchronous swap. (#47)
BaseCustomAccounting: Add interface IHookEvents to the contract in order to standardize event emissions in hooks (#47).
BaseCustomCurve: Add function _getSwapFeeAmount to calculate the amount of fees paid to LPs. (#47)
BaseHook: Update imports from v4-core (#66)

BaseDynamicAfterFee: Add interface IHookEvents to the contract in order to standardize event emissions in hooks (#47). Add functions _transientTargetUnspecifiedAmount, _transientApplyTarget, _setTransientTargetUnspecifiedAmount and _setTransientApplyTarget to handle the target unspecified and the apply flag using transient storage. Rename _getTargetOutput to _getTargetUnspecified and handle both exact input and exact output cases for targets. (#86)
BaseDynamicFee: Update imports from v4-core (#66)
BaseOverrideFee: Update imports from v4-core (#66)

AntiSandwichHook: Implementation of a sandwich-resistant pool using hooks. Specifically, it guarantees that no swaps get filled at a price better than the price at the beginning of the block. (#80)
LimitOrderHook: Hook to enable limit order placing on liquidity pools. The orders are placed as out-of-range liquidity increases. The hook allows for cancelling orders and withdrawing tokens after the orders are fulfilled. (#77)
LiquidityPenaltyHook: Hook that provides Just-in-time protection to pools. It penalizes LP fee collection during _afterRemoveLiquidity and disables it during _afterAddLiquidity if liquidity was recently added to the position. (#67)

IHookEvents: Interface created in order to standardize event emissions in hooks (#47)

Base contracts for building secure and modular Uniswap hooks, providing core functionality and common patterns for hook development.

BaseCustomAccounting: Base hook implementation for custom accounting, including support for swaps and liquidity management.
BaseCustomCurve: Base hook implementation for custom curves.
BaseHook: Base implementation for hooks.
BaseAsyncSwap: Base hook implementation for asynchronous swaps.

Hooks for managing and customizing pool fees, including dynamic fee adjustments, fee overrides, and post-swap fee calculations.

BaseDynamicFee: Hook to apply a manual dynamic fee via the Uniswap PoolManager contract.
BaseOverrideFee: Hook that overrides and applies a fee before swapping automatically.
BaseDynamicAfterFee: Hook that applies a fee based on a delta after swapping.

Libraries and general purpose utilities to help develop hooks.

CurrencySettler: Library used to interact with the PoolManager to settle any open deltas, with support for ERC-6909 and native currencies.
