Polymarket Concealed Position Association Feature Launched, StarkWare Introduces OffMarket

Odaily Planet Daily News: StarkWare has officially launched OffMarket to the public, allowing Polymarket users to trade without publicly associating positions with existing accounts. This service is based on zero-knowledge technology and Starknet's shared privacy liquidity pool, utilizing a non-custodial model where user keys are retained on the browser side. Each account has a deposit limit of 1,000 USDC, and the liquidity pool contract has been audited by OpenZeppelin and formally verified. Orders are still executed on Polymarket at the same market price between buyers and sellers, with transaction records, positions, order sizes, and history on Polygon remaining public. Others may still infer the identity of traders through transaction size or timing. OffMarket is not an official Polymarket product but is part of Polymarket's Verified Builder Program, adhering to geographic restrictions, including the prohibition of U.S. users. Financial Privacy Inc. holds the master viewing key for sanctions screening and disclosure of information upon lawful requests. Starknet's shared privacy pool currently holds approximately $1.5 million and 17,000 deposits.
