PerpFeeHook

EthereumRegistered

Collects a fixed 1.5% ETH-denominated fee on swaps in a single designated pool, minting fee claims to an external distributor contract. Records tick observations after each swap and pool initialization to maintain a 5-minute TWAP oracle via a 1024-entry ring buffer.

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.
