StarkWare has launched OffMarket, a platform enabling traders to use Polymarket without linking their positions to a public account. The platform runs on Starknet and uses zero-knowledge proofs to obscure user balances and trading activity on the Polygon network. Traders deposit USDC on Polygon and can start trading without ever creating a Polymarket account, with OffMarket managing derived wallets on their behalf. The platform taps into Polymarket’s existing order books, providing the same liquidity without the usual on-chain transparency. Public launch occurred around October 14, 2026, following a gradual rollout that began with a private alpha in July 2026.
