UniswapV4Hook

EthereumRegistered

Charges a 1.7% fee on buys (ETH) and sells (tokens), routing fees into a burn pot. Every 20 user swaps it signals a buyback-and-burn. Blocks sells in the same block as a buyback. Optionally restricts sells to an owner-controlled tx.origin allowlist, which any external caller can activate via superposition().

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.
