HypzFeeHook

RobinhoodRegistered

A volatility-based ETH fee hook for HypzLaunch pools. Charges fees in native ETH — buys pay on input in beforeSwap, sells pay on ETH output in afterSwap. The fee scales between a configurable base and max rate (both capped 1%–6.6%) based on tick movement of the prior swap. Exact-output swaps revert.

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.
