BullionTaxHook

RobinhoodRegistered

Levies a fixed 4% ETH trade tax on buys (ETH→GLD, taken in beforeSwap) and sells (GLD→ETH, taken in afterSwap) via BeforeSwapDelta/AfterSwapDelta returns. Accumulated ETH is held in the contract until flushed to a staking sink. Only exact-input swaps are permitted; exact-output reverts. Certain addresses (e.g. a buyback contract) can be exempted from the tax by the owner.

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.
