TestHook

RobinhoodRegistered

A buy/sell tax hook that deducts a configurable fee (up to 2% per side) from swap input amounts using v4's custom accounting (poolManager.take() + BeforeSwapDelta). Tax rates are fixed immutably at deploy time; proceeds are withdrawable only to the owner address set at construction.

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.

Can block LP withdrawals

It runs before liquidity is removed, so it can delay or refuse LP exits.

Gates who can add liquidity

It checks every deposit before it goes in.

✓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.

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