FrongHook

EthereumRegistered

A fee-collection hook for Frong ERC-404 token pools that enforces native-ETH pairing via beforeInitialize and takes a flat basis-point fee (capped at 5%) on every ETH-denominated swap using the BeforeSwapDelta and AfterSwapDelta return mechanisms, routing collected ETH to an owner-configurable fee sink address.

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.

Runs at pool creation

It runs when a pool is created, often to lock in that pool’s settings.
