Runs custom logic before a pool is created, and can reject pools it does not accept.
beforeInitialize = trueRuns custom logic right after a pool is created, such as recording its launch time.
afterInitialize = trueRuns custom logic before liquidity is added, and can block deposits.
beforeAddLiquidity = trueRuns custom logic before every swap. It can change the fee or block the trade.
beforeSwap = trueRuns custom logic after every swap.
afterSwap = trueCan change how much a trader pays or receives before the swap executes.
beforeSwapReturnDelta = trueCan take or add tokens to a trade's output after the swap executes.
afterSwapReturnDelta = true
These describe when the hook is called, not everything it does once called. Not used: afterAddLiquidity, beforeRemoveLiquidity, afterRemoveLiquidity, beforeDonate, afterDonate, afterAddLiquidityReturnDelta, afterRemoveLiquidityReturnDelta.
