FeeHook

BaseRegistered

Collects protocol fees on swaps by taking a configurable basis-point fee from the input token before the swap and from the output token after the swap. Fees are configurable per pool or via a default rate, controlled by an admin role, and accumulated in the contract for withdrawal to a designated fee recipient.

What it can do

Runs code on every swap

Its code executes inside each trade in pools that use it.

Can take tokens from swaps

It can take or add tokens during a swap. Fees, burns and custom curves work this way, and so do scams.
