Ring Few USDC Hook

EthereumRegistered

A hook that facilitates seamless 1:1 wrapping and unwrapping of an ERC20 token and its Ring Few-wrapped counterpart (fewToken) within a Uniswap v4 pool, intercepting swaps in beforeSwap to perform the wrap or unwrap operation and returning a delta to settle the exchange.

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.
