SolToss is a 100% PvP coin flip — you play against another real person, not the house.
Click Connect Wallet in the top-right. SolToss uses Phantom. On mobile, the Phantom app opens automatically. You sign a message to authenticate — no transaction is triggered at this step.
Choose one of four tiers: 0.001 / 0.01 / 0.1 / 1 SOL. You can only be in one game at a time. The tier grid shows how many opponents are currently waiting in each room.
Phantom will ask you to approve a transfer of your chosen amount to the SolToss escrow wallet. This is the only real transaction. Your SOL is held in the escrow until the match resolves — the escrow cannot spend your funds except to pay the winner or refund you.
Once your deposit confirms on-chain, you enter a 120-second waiting room. SolToss searches for another player who deposited the same amount. The countdown shows your remaining time. If no one joins in 120 seconds you are automatically refunded.
The moment an opponent is found, a single cryptographic coin flip runs on the server. Heads or tails is determined by a cryptographically secure random value (crypto.getRandomValues). The same flip decides both the visual animation you see and who gets paid — they are never separate rolls.
The winner receives 2× their bet minus a 2.5% fee. Payouts are sent automatically via a Solana transaction from the escrow. You can verify every payout on Solscan using the transaction link shown on the result screen.
| 0.001 SOL | Win 0.00195 SOL | fee: 0.00005 SOL |

Solana network gas fees (~0.000005 SOL) are paid by the escrow on payouts. Refunds have a small gas deduction (0.000005 SOL) to cover the refund transaction.
