AstroNodeFeeHook

RobinhoodRegistered

A volatility-based dynamic fee hook for ETH/token pools that charges ETH fees on buys (via beforeSwap delta) and sells (via afterSwap delta), scaling fees between a per-pool configurable base and max (1%–6.6%) based on the previous swap's tick movement. Fees are sent immediately to a per-pool fee recipient; exact-output swaps are rejected.

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.
