A modular Uniswap v4 hook that dispatches beforeSwap/afterSwap to an immutable accounting kernel via delegatecall, applying LP fee overrides and quote-take fees from pluggable frozen modules, with optional per-swap arbitrage correction payloads for authorized 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.

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