DynamicFeeHookV1

UnichainRegistered

A Uniswap v4 hook that applies a time-and-FDV-based dynamic fee schedule to newly launched token pools: fees start at 1% for the first 7 days, then step down based on pool age and token fully-diluted value (via an external oracle), reaching a minimum of 0.1% at ≥$100M FDV. Also maintains an onchain TWAP with up to 128 observations to support at-least-24h price history queries.

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.
