Ring Few CBBTC Hook

EthereumRegistered

Enables atomic 1:1 wrapping and unwrapping between an ERC20 token and its Few-wrapped equivalent within Uniswap v4 swaps, intercepting beforeSwap to perform the wrap/unwrap and returning the delta directly without going through the pool AMM.

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.
