Reading the hook.
The address, the bytecode, then a swap each way through its pool. A few seconds.
7 pools use this hook, the first one 19 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 2.00% of each swap on top of the pool fee.
Closed to outside LPs: only the hook's own liquidity is in the pool.
A fixed fee of 0%, written in the pool key.
Owned by 0xFAE990d08Ee278b3A806C293c5784c8AbC4B37c2. Owner-style functions: setFactory.
Not a proxy, no DELEGATECALL, no SELFDESTRUCT.
Each callback refused a call that did not come from the PoolManager.
7 pools over 18 days.
Measured at block 93,146,546. 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.
