CumHook

EthereumRegistered

Dynamic LP fee hook that adjusts fees based on cumulative price impact (CPI) across swaps. Fees scale with directional market imbalance and time-decay between swaps; each pool must be explicitly configured with fee bounds, decay parameters, and illiquidity scale before trading is permitted.

What it can do

Runs code on every swap

Its code executes inside each trade in pools that use it.

Sets its own swap fee

Pools using it let the hook choose the swap fee instead of a fixed tier.

Runs at pool creation

It runs when a pool is created, often to lock in that pool’s settings.
