Volatility-responsive dynamic LP fee hook using the Liquidity Book volatility-accumulator model. Sets per-swap LP fees based on recent price movement — low base fee in calm markets that surges with volatility and decays over configurable windows. No owner, no upgradeability; all parameters are immutable.

What it can do to your swap

  • 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 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.
