What it can do to your swap

  • Can take a fee from your outputAfter the pool fills your swap, the hook can keep part of what you were about to receive.
  • Runs code before your swap and can block itThe hook is called before every swap. It can revert, which makes your swap fail.
  • Runs code after your swap and can block itThe hook is called after every swap. It can revert, which undoes your swap.
  • Runs code when a pool is createdCalled once, when someone creates a pool with this hook.
  • Can charge a different fee on each swapThe pool's LP fee is dynamic: the hook sets it, swap by swap.
