UniHooks

WETHHook

BaseRegistered

A 1:1 ETH/WETH wrapper hook that allows users to swap between ETH and WETH within Uniswap V4 pools. It intercepts swaps to perform native wrapping and unwrapping, blocks direct liquidity operations, and requires pools to be initialized with zero fee.

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.
