Reading the hook.
The address, the bytecode, then a swap each way through its pool. A few seconds.
4 pools use this hook, the first one 30 d ago.
The address enables before swap returns delta, after swap returns delta. The hook is allowed to take; the next two checks measure whether it does.
It takes 2% of each swap on top of the pool fee.
Liquidity added and removed in the same block came back whole.
A fixed fee of 0%, written in the pool key.
Owned by 0x4dafe82666C2FfA75FE3F9c74A2E03e67Ee91ae0. Owner-style functions: upgradeToAndCall, setCoordinator, transferOwnership.
It is a proxy. The code that runs lives at 0xB55ece1aeD9AD524956cc5F1e6a461fF1F318a1c.
Each callback refused a call that did not come from the PoolManager.
4 pools over 29 days.
Measured at block 93,329,415. A hook with an owner or a dynamic fee can behave differently later; scan again before a large trade.
A v4 hook's permissions are the last fourteen bits of its address. The PoolManager calls only what they switch on.
A small swap each way and a liquidity round trip, run through the PoolManager and this hook inside a call that is never sent. The pool fee is expected; anything else missing is the hook.

Selectors found in the dispatcher, named from the public signature database. Red ones are what an owner usually keeps for itself.
