The service says positions are not publicly associated with the OffMarket identity, but the trades themselves remain public. That limited account-link claim does not establish invisibility to the service or to blockchain analysis. Read privacy and custody terms to understand the boundary. Shared markets and liquidity do not guarantee an identical execution price across times or order sizes. Compare the same contract, side and depth before reviewing the final quote. The documented deposit route is USDC on Polygon, and the site says trading is unavailable from the United States. ### Who it is for - Comparing trading interfaces with account-link privacy features. - Using an interface connected to familiar Polymarket liquidity. - Choosing between Google and existing-wallet sign-in. ## Features and coverage - **Shared market universe** Browse Polymarket outcomes rather than a separate contract catalog. - **Shared order book** Access the underlying venue's liquidity and prices. - **Account-link privacy claim** The provider says positions are not publicly linked to the OffMarket account. - **Sign-in choices** Use Google or connect a crypto wallet. - **Polygon deposits** Follow the documented USDC-on-Polygon funding route. - **Public browsing** Inspect the market interface before signing in. ## Workflows with OffMarket ### Compare an order quote Open the same contract in both interfaces and compare side, depth and order terms. ### Review privacy boundaries Work out the account-link feature’s boundary from the privacy policy and custody terms. Distinguish what the provider says is not publicly associated with an OffMarket account from what the service or blockchain analysis may still reveal. ### Check the funding route Confirm Polygon and the exact supported USDC asset in the deposit flow before sending funds. ## Pricing and total cost The public description does not provide a complete platform-fee table. The trade confirmation and applicable terms are needed to identify the costs of the chosen route. ## Getting started **Before you start:** Account-link privacy does not establish that activity is invisible to the service or blockchain analysis. 1. Open the official app. 2. Browse the desired market and read its rules. 3. Review the privacy policy and terms. 4. Choose Google or wallet sign-in. 5. Check the exact Polygon deposit instructions. 6. Review the order quote before confirming. Trades remain publicly visible even though the provider describes account-link privacy. ## Useful links ### What to check - Account-link privacy does not establish that activity is invisible to the service or blockchain analysis. - The site says trading is unavailable from the United States. - Shared liquidity does not mean identical fills at different times or sizes. - Public platform-fee detail is incomplete. A closer look ## Ratings & reviews Editorial rating **2.5**/ 5 0 user reviews PredictionToolkit editorial ### Our take on OffMarket Familiar markets and shared-book routing make the workflow understandable. Account-link privacy remains a limited provider claim; public trades and incomplete fee details leave material boundaries to assess. Based on documented features, setup and access terms.
