StarkWare has released OffMarket, a privacy service for Polymarket users, The Block reported on Oct. 14.
OffMarket lets users trade on Polymarket without publicly linking their accounts to their positions.
OffMarket has operated on a limited basis since August, the report said. It uses StarkNet zero-knowledge technology, and the per-account deposit limit is 1,000 USDC. StarkWare plans to adjust the limit based on demand and usage. Orders are matched on Polymarket against existing buyers and sellers at the same market price.
All Polymarket trades are recorded on the Polygon blockchain. Anyone can use these records to see account-level positions, order size and trading history.
OffMarket is a non-custodial service. Users manage their own keys in their browser. OffMarket cannot prevent traders from being identified by trade size or timing. If few people use a pool at the same time, it may become easier to infer the original depositor, The Block reported.
