VolatilityFeeHook

RobinhoodRegistered

A Uniswap v4 hook that charges a volatility-adjusted fee on every swap, with the rate scaling linearly from a base fee to a maximum based on how far the previous swap moved the tick price. Fees are taken in the pool's quote currency as ERC-6909 claims and forwarded to an immutable fee wallet via a permissionless sweep().

It can take or add tokens during a swap. Fees, burns and custom curves work this way, and so do scams.
