Hook Logic

When this hook runs, read from the permissions encoded in its address

  • Runs custom logic before a pool is created, and can reject pools it does not accept.

    beforeInitialize = true
  • Runs custom logic right after a pool is created, such as recording its launch time.

    afterInitialize = true
  • Runs custom logic before every swap. It can change the fee or block the trade.

    beforeSwap = true
  • Runs custom logic after every swap.

    afterSwap = true
  • Can change how much a trader pays or receives before the swap executes.

    beforeSwapReturnDelta = true
  • Can 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: beforeAddLiquidity, afterAddLiquidity, beforeRemoveLiquidity, afterRemoveLiquidity, beforeDonate, afterDonate, afterAddLiquidityReturnDelta, afterRemoveLiquidityReturnDelta.
