StarkWare launches OffMarket, letting Polymarket users trade privately via Starknet zero-knowledge pool

OffMarket has been in limited release since August and caps deposits at $1,000 USDC per account, with StarkWare saying the limit will adjust to demand. Orders execute on Polymarket against the same buyers and sellers at the same prices, and the service is non-custodial, with funds in Starknet's shared privacy pool and positions held in Polymarket contracts under signature-derived wallets. StarkWare's spokesperson acknowledged transaction size and timing can still identify traders, and that OffMarket is not a Polymarket product, though it is in the verified builder program.
