StarkWare has opened its OffMarket service to the public, enabling users to trade on Polymarket without publicly linking positions to existing accounts. The privacy-focused tool operates on Starknet's shared privacy pool and executes orders directly on the Polymarket platform with identical counterparties and market pricing as standard trades. The service, which has been in limited early release since August, currently enforces a single USDC deposit limit of $1,000. OffMarket is fully non-custodial, with users retaining complete control of their private keys within the browser throughout the trading process.
