Reading the hook.
The address, the bytecode, then a swap each way through its pool. A few seconds.
15 pools use this hook, the first one 46 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, but a high one: 3%.
Owned by 0x50166E090Cc4bc9543EEfE98d8aC993A7e9cD76B. Owner-style functions: withdrawAll, withdrawPool, transferOwnership.
Not a proxy, no DELEGATECALL, no SELFDESTRUCT.
Each callback refused a call that did not come from the PoolManager.
15 pools over 45 days.
Measured at block 92,999,908. 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.
