VolatilityFeeHook

RobinhoodRegisteredLaunch a pool with this hook

Charges a volatility-adjusted fee on every swap, scaling linearly from a base rate to a maximum based on how far the previous swap moved the price (tick delta). Fees are collected in the pool's quote currency via delta returns, accrued as ERC-6909 claims on the PoolManager, and redeemable permissionlessly via `sweep()` to a fixed, immutable fee wallet.

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.
