Full-stack prediction markets: live prices, orders and positions, wallet and on-chain settlement. Product experience is aligned with international leaders; branding and rules are independent.
Our Mission
TossMarket is building the world's most accurate source of truth about future events. We empower people to put their knowledge and capital to work, creating powerful incentives for information discovery and sharing. By aggregating the wisdom of crowds, we provide real-time probability data that's often more accurate than traditional forecasting methods.
How It Works
Markets are Created
The current build creates markets through the admin console and supports yes/no event questions across multiple categories.
People Trade
Users place YES and NO orders, manage open positions, and watch prices update in real time.
Markets Resolve
Administrators resolve markets, winning positions are settled, and resolved exposure is archived for later review.
Current Platform Model
The current implementation now runs wallet sign-in and treasury funding on Solana while keeping order matching, position accounting, and settlement mirrored in the application ledger. Wallet authentication is standardized around browser-injected Solana wallets and ed25519 message verification; direct market execution on-chain is the remaining roadmap step.
Wallet Sign-In
Users authenticate by signing a message with Phantom, Solflare, Backpack, or another injected Solana wallet.
Hybrid Treasury
Deposits and withdrawals now execute on-chain, while available balance, locking, and settlement still mirror into the app ledger for trading.
Realtime Sync
Orders, trades, positions, and notifications propagate over Socket.IO.
