Reading the hook.
The address, the bytecode, then a swap each way through its pool. A few seconds.
5 pools use this hook, the first one 41 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%, written in the pool key.
Owned by 0xE229462E2445D8093D5BE252e7f51386F1655409. Owner-style functions: upgradeTo, upgradeToAndCall, transferOwnership.
It is a proxy. The code that runs lives at 0x85e05D619F0C43D270a7eD95579c417e377514Fd.
Each callback refused a call that did not come from the PoolManager.
5 pools over 41 days.
Measured at block 93,206,398. 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.
