StarkWare has opened OffMarket to the public, allowing Polymarket users to trade without publicly linking their positions to their accounts. The service leverages zero-knowledge technology on Starknet and aims to address user privacy concerns arising from the public transparency of Polymarket trades, following reports of large bets being tracked and insider trading. Currently, the deposit limit is 1,000 USDC per account, and the service is non-custodial, allowing users to retain control over their keys. OpenZeppelin has audited the privacy pool contracts for the service and found no critical or high-severity issues.
