UniswapV4Hook

EthereumRegistered

Burns 1.2% of each swap as a deflationary mechanism: buy-side fees accumulate in a native ETH pot used to periodically buy back and burn the token (every 20 swaps); sell-side fees are taken directly and burned. Only exact-input swaps are supported. Liquidity additions are restricted to a single one-time event by the hook.

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.
