UniswapV4Hook

EthereumRegisteredLaunch a pool with this hook

Collects a 1.7% fee on buys (ETH) and sells (token), routing buy fees to a burn pot for periodic buyback-and-burn operations. Every 20 swaps with a non-empty burn pot, a buyback is flagged; sells in the same block as a buyback are blocked. Liquidity addition is permanently gated to a single provider, and sell access can be restricted to an admin-controlled allowlist via a publicly-triggerable `timeBased` flag.

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.
