Immutable dynamic-fee hook where a per-pool worker posts directional LP fee budgets (0.025%–0.9%, TTL 5 min, defaulting to 0.05% on expiry). beforeSwap overrides the LP fee with 90% of the posted budget; afterSwap collects a 10% platform fee as a return delta, minted as ERC-6909 claims to the hook and sweepable to a configured treasury.

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.
  • 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.
  • Can charge a different fee on each swapThe pool's LP fee is dynamic: the hook sets it, swap by swap.
