HookrModularHookV4

RobinhoodRegistered

A modular Uniswap v4 hook that delegates swap accounting to a pinned immutable kernel via delegatecall, supporting per-pool module stacks, dynamic LP fees, and an optional arbitrage correction mechanism that triggers nested swaps during beforeSwap/afterSwap for trusted routers.

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.

Gates who can add liquidity

It checks every deposit before it goes in.

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: HookrModularHookV4).

iCan change swap amountsIt has a ReturnDelta permission. Normal for fees and burns, but also how fake-quote hooks steal.
