Reading the hook.
The address, the bytecode, then a swap each way through its pool. A few seconds.
8 pools use this hook, the first one 98 d ago.
None of the permissions that let a hook take from swaps or from LPs are switched on.
It takes 3% of each swap on top of the pool fee.
Liquidity added and removed in the same block came back whole.
Its pools use a dynamic fee that the hook sets before every swap. It stands at 0% now and can change.

Not a proxy, no DELEGATECALL, no SELFDESTRUCT.
Each callback refused a call that did not come from the PoolManager.
8 pools over 97 days.
Measured at block 93,088,852. 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.
