FlywheelV4Hook

EthereumRegistered

A buyback-and-burn hook that collects a 1.2% fee on every swap — ETH on buys into a burn pot, tokens on sells queued for burning — and periodically executes autonomous buybacks by swapping accumulated ETH for the pool token and burning the proceeds.

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.

Gates who can add liquidity

It checks every deposit before it goes in.

Runs at pool creation

It runs when a pool is created, often to lock in that pool’s settings.
