ShiftHook

EthereumRegistered

A fee hook for wstETH/ETH pools that levies a flat configurable toll (in basis points) on the wstETH leg of every swap, covering all four swap shapes (exact-input/output × buy/sell) via both beforeSwap and afterSwap return deltas. Toll proceeds are split between an immutable Bus contract (distributes to seat holders) and an immutable Treasury address.

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.
