TwinHook

RobinhoodRegisteredLaunch a pool with this hook

Singleton hook shared by Twin launch pools. Restricts pool initialization to a registered launcher; charges configurable buy/sell taxes on swaps via afterSwapReturnDelta, sending proceeds to a vault. Maintains per-pool TWAP and block-start tick snapshots for manipulation resistance.

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.

✓No owner foundNo owner() function: nobody has an admin switch (as far as the standard check goes).

✓Listed in Uniswap’s hook registryRegistered with Uniswap Labs (a listing, not a security review).

✓Source code publishedThe code on the block explorer matches what's deployed (contract: TwinHook).

iCan change swap amountsIt has a ReturnDelta permission. Normal for fees and burns, but also how fake-quote hooks steal.
