YunaFeeHook

RobinhoodRegistered

Applies directional ETH fees on swaps in a native ETH pool: a buy fee (ETH-specified swaps) is routed to a holder pool via BeforeSwapDelta, and a sell fee (ETH-unspecified swaps) is split between a team treasury and holder pool via AfterSwapDelta. All fees are taken in currency0 (native ETH) using poolManager.take().

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.
