Reading the hook.
The address, the bytecode, then a swap each way through its pool. A few seconds.
225 pools use this hook, the first one 10 d ago.
The address enables before remove liquidity, before swap returns delta, after swap returns delta. The hook is allowed to take; the next two checks measure whether it does.
Every swap through it was refused: NotWallet. Only an approved router may get through.
Closed to outside LPs: only the hook's own liquidity is in the pool.
A fixed fee of 0%, written in the pool key.
No owner() but it has setBuybackTreasury, collectFees, setOpsWallet.
Not a proxy, no DELEGATECALL, no SELFDESTRUCT.
Each callback refused a call that did not come from the PoolManager.
225 pools over 10 days.
Measured at block 92,891,609. 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.
