FiverHook

EthereumRegistered

A swap-fee levy hook that deducts a configurable percentage (levy rate, default 1%, max 5%) of each swap's quote-token amount from registered token pools, using beforeSwap and afterSwap return deltas to extract the toll and accrue it to the token issuer's claimable stash.

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.
