Trading on Supermission
Every trade on Supermission executes on Polymarket’s Central Limit Order Book (CLOB) — the deepest prediction market liquidity on the planet with$44B+ in lifetime volume. Same prices, same liquidity. Your orders go directly to the orderbook with no mempool exposure (no front-running risk).
Execution infrastructure
When you confirm a trade, here’s what happens:Balance check
The system checks your USDC balance and determines if bridging is needed. Since Polymarket’s CLOB operates on Polygon, USDC is automatically bridged from Base to Polygon if required.
Chain preparation
Your Privy embedded wallet switches to Polygon. Gas funding is handled automatically — you never need to hold MATIC/POL.
USDC approval
If needed, a USDC approval transaction is signed. This allows the Polymarket contracts to move USDC on your behalf.
Order signing
The system fetches the best bid/ask from the CLOB to set a slippage-protected price (2.5% slippage tolerance). Your MPC wallet signs the order.
Order submission
The signed order is submitted to Polymarket’s CLOB. For market orders (FAK), it fills immediately. For limit orders (GTC), it sits on the book.
