UniswapV4Hook

EthereumRegistered

A buy-and-burn hook that charges a 1.7% fee on buys (ETH accumulated into a burn pot for periodic token buybacks every 20 swaps) and sells (tokens queued for direct burning). Exact-output swaps always revert. Sell access can be restricted to an owner-managed allowlist when enabled per token.

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.
