StarkWare Launches OffMarket, Polymarket Users Can Trade Anonymously

According to The Block, StarkWare has officially launched the OffMarket privacy trading service to the public, allowing users to trade on Polymarket without publicly linking their account identities. Since August this year, the service has entered a limited beta testing phase. Built on Starknet zero-knowledge technology and operating via a shared privacy pool, the pool currently holds approximately $1.5 million in assets and has recorded around 17,000 cumulative deposits. The current maximum deposit per account is 1,000 USDC, which StarkWare stated will be dynamically adjusted based on demand. OffMarket operates on a fully non-custodial model where users retain control of their own keys. Orders are executed on Polymarket's native markets under identical pricing and fee structures, with private trades taking approximately one minute to execute and withdrawals requiring a few minutes. Notably, OffMarket is not an official Polymarket product, nor does it have a formal partnership with the platform, and it also explicitly prohibits access for US users.
