HookFee

EthereumRegistered

A Uniswap v4 hook that collects a configurable basis-points fee on token1-to-token0 swaps (non-zeroForOne), redirecting a portion of the currency0 output to a fixed fee recipient via afterSwapReturnsDelta. The fee rate is set by an owner and can be updated at any time.

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.
