BitPredict

BitPredict is the first fully on-chain prediction market built on Bitcoin L1 via OP_NET. Users bet on real-world outcomes — crypto prices, politics, sports, tech — using WBTC (wrapped BTC through NativeSwap). Every bet, stake, and payout is a real Bitcoin transaction. The platform uses a parimutuel model: all bets pool per side, winners split the pot proportionally. No liquidity providers needed, no counterparty risk — the smart contract holds all funds. The server acts only as an oracle and indexer, never touching user money. 5 smart contracts deployed on testnet: PredictionMarket (parimutuel engine), WBTC (NativeSwap BTC wrapper), StakingVault (stake WBTC, earn 40% of platform fees with auto-compound), Treasury (protocol revenue collection), and PriceOracle (BTC/ETH/SOL feeds for fast bets). Key features: 3-step on-chain bet flow (approve → placeBet → index), Predict & Earn Vault with projected APY and earnings calculator, AI market signals powered by Gemini, P&L tracking, leaderboard, social trading. Full security audit completed — 3 critical + 4 high findings fixed (cancelMarket, emergencyWithdraw, NoWinnerRefund, timelock on claims, cross-market drain prevention). Built with Bob from day one — contract architecture, security patterns, OP_NET integration, and in-app AI chat all powered by the Bob MCP agent.
