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 52 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 1% on top of the pool fee.
Liquidity added and removed in the same block came back whole.
A fixed fee of 0.10%, written in the pool key.
Owned by 0x4c1fBa84813F1D97C07cC4e408e4D19C7aF8cB1D. Owner-style functions: setOwner, upgradeToAndCall, setFactory, setFactoryAllowed, burnedBase, claim.
It is a proxy. The code that runs lives at 0xc9B23f3F9e8eCa1bf51c38A6baaC118a54fAA8C0.
Each callback refused a call that did not come from the PoolManager.
4 pools over 51 days.
Measured at block 93,270,575. 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.
