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 54 d ago.
None of the permissions that let a hook take from swaps or from LPs are switched on.
A swap through it pays the pool fee and nothing else.
Closed to outside LPs: only the hook's own liquidity is in the pool.
Its pools use a dynamic fee that the hook sets before every swap. It stands at 0% now and can change.
Owned by 0x393E3E09A771e9D63bb35D3994fb5cB4193BdA4e. Owner-style functions: transferOwnership, setGasThreshold, paused, setDefaultFee, setPaused.
Not a proxy, no DELEGATECALL, no SELFDESTRUCT.
Each callback refused a call that did not come from the PoolManager.
7 pools over 54 days.
Measured at block 93,112,870. 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.
