TaxHook

RobinhoodRegistered

A Uniswap v4 hook that applies fixed buy (3%) and sell (6%) taxes on swaps involving a designated token, deducted from the unspecified currency in afterSwap as ERC-6909 claims. Fees accumulate to the hook contract and are swept permissionlessly to a treasury address governed by a 3-day owner-controlled timelock.

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.
