Round mechanics
Deploy. Reveal. Payout.
Two minutes to stake a tile. Multi-hash entropy draws the winning square on Base Sepolia.
01
Deploy on a tile
Pick one of nine squares and stake $OAR priced in USD.
02
Multi-hash settle
After the window closes, the keeper locks entropy, waits five blocks, then mixes several future blockhashes to draw the vein.
03
Payout lands
Winners share the pot. Keeper pushes claims and refunds — no extra wallet sign.
Protocol fee: 5% of losers’ pool on wins · 2% on refunds. Fee share with top betters coming.
