V4TaxHook

RobinhoodRegistered

A shared Uniswap v4 hook that charges a fixed 1% tax on the WETH/base-asset side of all buys and sells. The tax is minted to the launched token contract as an ERC-6909 claim in the PoolManager. Pool creation is gated to a factory, blocking third-party pool squatting; partial fills on base-asset-specified swaps are rejected to prevent tax overcharging.

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.
