Launchpad hook that charges a creator fee on every swap output (split 70/30 between creator and protocol) and caps exact-in WETH buy amounts during a configurable time-based launch window using a 3-phase curve (flat cap → linear ramp → uncapped) to reduce sniping at launch. Also supports multi-token LP reward distribution ("juice rail") using a fee-growth accumulator pattern.

What it can do to your swap

  • Can block swapsSwaps are gated (temporal): only some addresses, or only at some times, can trade through it.
  • Can take a fee from your outputAfter the pool fills your swap, the hook can keep part of what you were about to receive.
  • 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.
