Reading the hook.
The address, the bytecode, then a swap each way through its pool. A few seconds.
28 pools use this hook, the first one 47 d ago.
None of the permissions that let a hook take from swaps or from LPs are switched on.
No pool with liquidity to swap through yet.
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.
28 pools over 47 days.
Measured at block 92,984,102. 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.
