FeeHook

ArbitrumRegistered

Takes a configurable fee (between 1% and 10%, owner-reducible only, never raiseable) on every swap via afterSwap. Reserve-currency fees are deposited into a FeeVault; non-reserve (token) fees are burned. The fee is charged on the unspecified currency and returned via afterSwapReturnDelta.

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.
