BangFeeHook

RobinhoodRegistered

A tax hook for an ETH/index-token pool that charges a fixed fee (up to 4%) on every swap by diverting ETH to a treasury address. ETH-specified swaps are taxed in beforeSwap via a BeforeSwapDelta; index-token-specified swaps are taxed in afterSwap via an AfterSwapDelta.

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.

Runs at pool creation

It runs when a pool is created, often to lock in that pool’s settings.
