PillHook

ArbitrumRegistered

Collects a flat 1% toll on the ETH leg of all swap forms (exact-in/exact-out, both directions) in a single deployer-pinned pool. Toll accumulates as ERC-6909 claims in the PoolManager and is withdrawable to a fixed vault address via permissionless collect(). The fee rate can only be lowered, never raised, by the deployer.

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.
