Reading the hook.
The address, the bytecode, then a swap each way through its pool. A few seconds.
3 pools use this hook, the first one 33 d ago.
The address enables after swap returns delta. The hook is allowed to take; the next two checks measure whether it does.
A swap through it pays the pool fee and nothing else.
Liquidity added and removed in the same block came back whole.
A fixed fee of 1%, written in the pool key.
Owned by 0xd0f36F34eD3B665C5001663ECFb7764468525bdf. Owner-style functions: setFactory.
Not a proxy, no DELEGATECALL, no SELFDESTRUCT.
Each callback refused a call that did not come from the PoolManager.
3 pools over 32 days.
Measured at block 93,418,499. 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.
