FeeHook

RobinhoodRegistered

Levies a flat 1% protocol fee in native ETH on every swap of a native-ETH/token pool, using BeforeSwapDelta and afterSwapReturnsDelta to take the fee via PoolManager custom accounting. Fees are split between a treasury (10% default, up to 40% max) and a per-pool creator address (minimum 60%), accrued in-contract and withdrawn on demand.

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.
