WstETHHook

EthereumRegistered

A Uniswap v4 hook that enables seamless wrapping and unwrapping between stETH and wstETH during swaps, applying the dynamic stETH/wstETH exchange rate in beforeSwap and settling token deltas directly with the pool manager. Liquidity additions are blocked; all exchange is handled exclusively through the hook.

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.
