PulseV4Hook

RobinhoodRegistered

Adjusts LP fees dynamically using time-decayed trading volume across nearby tick buckets (half-life one hour), with an additional gas-price-proportional project fee capped at 0.30%. The owner can pause protocol fee collection and withdraw accrued ERC-6909 revenue; LP principal is never touched by the hook.

What it can do

Runs code on every swap

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

Can take tokens from swaps

It can take or add tokens during a swap. Fees, burns and custom curves work this way, and so do scams.

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.

✓No owner foundNo owner() function: nobody has an admin switch (as far as the standard check goes).
✓Listed in Uniswap’s hook registryRegistered with Uniswap Labs (a listing, not a security review).
✓Source code publishedThe code on the block explorer matches what's deployed (contract: PulseV4Hook).
iCan change swap amountsIt has a ReturnDelta permission. Normal for fees and burns, but also how fake-quote hooks steal.
