UniHooks

FeeHook

EthereumRegistered

A hook that charges a tiered ETH-denominated swap fee (0.5%–1.25% based on token market cap) on ETH/token pools. In beforeSwap and afterSwap it skims the fee from the ETH leg of each swap via BeforeSwapDelta/AfterSwapDelta, accruing 75% to a hardcoded protocol wallet and 25% to a per-token registered creator, redeemable via a pull-based claim().

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.
