TwigWrapHook

BaseRegistered

TwigWrapHook is a Uniswap v4 hook on Base. Token wrapper hook for a fee-0 GITLAWB/TWIG pool that intercepts all swaps in beforeSwap and fulfills them by wrapping GITLAWB into TWIG or unwrapping TWIG into GITLAWB at a 1:1 ratio via ERC20Wrapper. Liquidity operations always revert; the contract has no owner, no admin functions, and no upgrade mechanism.

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.
