Ring FewV2 Shell Hook

EthereumRegistered

Uniswap v4 hook that executes each swap on the canonical Ring Swap v2 (FewV2) FewToken pair: it wraps the input 1:1 into its FewToken, swaps on the pair at live reserves, unwraps the output and settles through PoolManager. It needs no hookData and adds no hook fee. A two-step owner manages a time-locked token allowlist, and a guardian or the owner can pause swaps without blocking liquidity withdrawal.

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.

Runs at pool creation

It runs when a pool is created, often to lock in that pool’s settings.
