FewTokenHook

EthereumRegistered

Wraps and unwraps "few tokens" (a wrapped ERC20 variant) 1:1 during swaps via beforeSwap, settling deltas directly so the pool holds the wrapped token while users interact with the underlying token. Enforces zero-fee pools containing only the wrapper and underlying currency pair.

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.
