# 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:

<Steps>
  <Step title="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.
  </Step>

  <Step title="Chain preparation">
    Your Privy embedded wallet switches to Polygon. Gas funding is handled automatically — you never need to hold MATIC/POL.
  </Step>

  <Step title="USDC approval">
    If needed, a USDC approval transaction is signed. This allows the Polymarket contracts to move USDC on your behalf.
  </Step>

  <Step title="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.
  </Step>

  <Step title="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.
  </Step>

  <Step title="Optimistic position update">
    Your position appears in the Portfolio tab immediately via optimistic updates. The optimistic entry auto-cleans when real position data arrives from Polymarket's API.
  </Step>
</Steps>
