MemeFeeHook

RobinhoodRegistered

Charges a constant 4% swap tax in native ETH pools (currency0 = address(0)), routing the fee to a fixed treasury address via return deltas in beforeSwap and afterSwap. Non-ETH pools pass through untaxed. No owner, admin keys, or adjustable parameters.

It can take or add tokens during a swap. Fees, burns and custom curves work this way, and so do scams.
