Reading the hook.
The address, the bytecode, then a swap each way through its pool. A few seconds.
13 pools use this hook, the first one 26 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.
Closed to outside LPs: only the hook's own liquidity is in the pool.
A fixed fee of 0.42%, written in the pool key.
Owned by 0xbeef8f589f70d1FdD9Ed7731378C26bb5950156d. Owner-style functions: setOwner.
Not a proxy, no DELEGATECALL, no SELFDESTRUCT.
Each callback refused a call that did not come from the PoolManager.
13 pools over 25 days.
Measured at block 93,031,541. 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.
