DoubleBackedFeeHook

RobinhoodRegistered

Takes a fixed 3% swap fee always in native ETH (currency0), splitting fee collection between beforeSwap (ETH-specified trades) and afterSwap (ETH-unspecified trades). All fees are forwarded to a vault address. Pools without native ETH as currency0 pass through without a fee.

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.
