Probity
A reference implementation for Arc-native prediction-market infrastructure, offered as a forkable repo, deployed on Arc testnet with on-chain artifacts and receipts. It exposes MarketFactory-based creation of independent markets, YES/NO market contracts with USDC-style settlement, wallet-based buy/sell-back/portfolio/claim flows, resolver and admin workflows for testnet resolution, external signal curation that spins up separate Arc-native markets, frontend patterns for Arc Testnet wallet connection and faucet guidance, and deployment scripts with ABI exports and demo-ready config. It is a plain binary prediction market with no AI layer.
