Safety report

Automated checks, not an audit

✓Not upgradeableNo proxy pattern found: the code is fixed.

!Has an adminowner() is 0x9230…3d1e. That account can usually change fees, limits or allowlists after you trade.

!Not in Uniswap’s hook registry, not tradeable in Uniswap’s app yetUnregistered hooks get less scrutiny. Most scam hooks are unregistered. It runs code on swaps, so Uniswap’s app only routes it once Uniswap Labs approves it, and it isn’t approved yet. Adding liquidity still works, and other apps can trade it.

!Source code not publishedNobody can read what this hook actually does. Treat it as a black box.

?No audit linkedAutomated checks only.
