CLOCKFeeHook

RobinhoodRegistered

A volatility-adaptive swap-fee hook for ETH/token pools launched via the CLOCK launchpad. Charges fees in native ETH on buys (via beforeSwap delta) and sells (via afterSwap delta), scaling between a configurable base and max rate (0.3%–5%) based on the tick movement of the previous swap. Only supports exact-input swaps; 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.
