Volatility-responsive dynamic LP fee hook porting the Liquidity Book (LFJ joe-v2, MIT) volatility-accumulator mechanism to Uniswap v4. Fee rises with recent price movement and decays back to a per-pool base rate, hard-capped at 10%. Config is per-pool, frozen at initialization; no owner or admin functions.

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.
