WETHHook

EthereumRegistered

WETHHook turns a v4 pool into an ETH / WETH wrapper. Swaps mint or burn WETH 1:1 against native ETH via the WETH9 contract. Deposits take ETH from the PoolManager and settle the minted WETH back; withdrawals unwrap and return native ETH. Direct liquidity provision is disabled.

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.
