Charges a volatility-scaled quote-side fee on every swap in Uniswap v4 pools opened with zero LP fee, collecting fees as ERC-6909 claims and forwarding them to a designated fee wallet. The fee rate adjusts between a configurable base and maximum BPS (capped at 5.3%) based on the tick movement of the previous swap.

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 after a pool is createdCalled once, right after a pool with this hook is created.
