!Source code not publishedNobody can read what this hook actually does. Treat it as a black box.
✓Code is fixedNo proxy, so what you integrate with today is what runs tomorrow.
✓No owner foundNo owner() function, so no single admin key (as far as the standard check goes).
Pools2 to review
!Pools don’t trade in Uniswap’s app yetIt 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.
!Can reject swapsbeforeSwap runs on every trade and can revert it. Used for launch limits and start times; check when it says no, since holders see a failed trade on the token.
iControls the swap fee1 of its pools use a dynamic fee the hook sets per trade, so LP income depends on its logic.
iControls who can add liquiditybeforeAddLiquidity checks every deposit, so outside LPs may be blocked.
✓Doesn’t touch swap amountsTraders get exactly what the pool’s curve and fee give.
