Charges a 400 bps protocol fee on the native ETH side of all native/ERC-20 pool swaps, collected via beforeSwap and afterSwap return deltas and sent to an immutable fee treasury. During a configurable launch window (default 720 seconds), an exponentially-decaying anti-sniping surcharge (default starting at 6000 bps, tau=158s) and per-swap/per-wallet token amount caps are enforced.

What it can do to your swap

  • Can take a fee from your outputAfter the pool fills your swap, the hook can keep part of what you were about to receive.
  • Can change the price you getBefore your swap runs, the hook can take or add tokens, so the amount you get is set by its code as well as the pool.
  • Runs code before your swap and can block itThe hook is called before every swap. It can revert, which makes your swap fail.
  • Runs code after your swap and can block itThe hook is called after every swap. It can revert, which undoes your swap.
  • Runs code when a pool is createdCalled once, when someone creates a pool with this hook.
