FALLaunchHook

EthereumRegistered

Charges a 4% fee (0.5% to a fee collector, 3.5% to a harvester contract) on exact-input swaps involving ETH (currency0) — deducting from ETH input on ETH→token swaps via BeforeSwapDelta, and from ETH output on token→ETH swaps via AfterSwapDelta. Fee recipients and governor address are configurable by the current governor.

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.
