Your positions on Polymarket have always been an open book—anyone can inspect them on-chain. StarkWare has open-sourced OffMarket; essentially, it puts a shield around your main wallet so every prediction-market bet isn’t linked back to the same address.

It uses Starknet’s zero-knowledge privacy pool: deposit $USDC, then derive a new wallet to trade the same Polymarket markets. It’s non-custodial, with the keys in your browser; OpenZeppelin audited the pool, and StarkWare also formally verified it. Each account is initially capped at $1000 $USDC, with the limit to be adjusted based on usage. According to L2BEAT, the shared pool holds around $1.5M and has seen about 17,000 deposits—when there are few users, it’s still not hard to infer who made the original deposit.

Trading amounts and timing remain public; U.S. users still can’t get in. This isn’t an official Polymarket product, just a verified builder. The $STRK team just shipped Shadow Accounts and has now brought privacy to prediction markets—the product pace is pretty brisk.

Just filtering, not educating. This is not investment advice.
