A Uniswap v4 hook for token launches with a time-decaying dynamic fee curve. The hook overrides pool LP fees to zero and skims fees via return deltas, distributing them between a creator recipient, treasury, permanently-locked LP compounding, and holder reflections (via IDividendToken.notifyReward). Whitelisted launch wallets pay the floor fee during the opening window.

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.
  • Runs code after a pool is createdCalled once, right after a pool with this hook is created.
  • Can charge a different fee on each swapThe pool's LP fee is dynamic: the hook sets it, swap by swap.
