what's cBaseMarket?

cBaseMarket is an on-chain confidential prediction market protocol built on the Base blockchain. Developed by the team Cracked Devs at the ETHMumbai 2026 hackathon, it tackles key vulnerabilities in existing prediction markets, including frontrunning, MEV exploitation, insider trading, and information asymmetry. The protocol uses ENS for user identity verification upon login. To maintain confidentiality, user predictions are fragmented into multiple smaller positions via stealth addresses generated with the BitGo SDK. These positions are dynamically rebalanced between Yes and No outcomes throughout the market's duration, with true positions only revealed at resolution. It won prizes from ENS and Base, and leverages Inco for privacy.
