HalloMarketsFeeHook

RobinhoodRegisteredLaunch a pool with this hook

A volatility-based dynamic fee hook for HalloMarkets launchpad pools. Charges ETH fees between 1–5% on buys (via beforeSwap delta on input) and sells (via afterSwap delta on output), scaling the fee based on the tick movement of the previous swap. Fees are sent directly to a per-pool fee recipient on every swap.

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.
