ArbHook

ArbitrumRegistered

Hook that intercepts swaps from a single authorized address ("muscle"), computing a custom BeforeSwapDelta based on input/output token decimals to absorb the swap amounts itself. All other callers receive a zero delta pass-through and proceed with standard pool behavior.

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.
