EthereumRegistered

A hook that enables 1:1 wrapping and unwrapping between ETH and fwWETH (Few Wrapped ETH) in Uniswap v4 pools, intercepting swaps via beforeSwap and using delta returns to handle token conversions entirely within 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.
