Before your first trade

  1. Connect a wallet on Arc Testnet, the interface prompts you to switch network if needed.
  2. Hold USDC on Arc. Gas on Arc is paid in USDC, so keep a small buffer.
  3. Read the market's rules tab, including the resolution source and timezone.
  4. Acknowledge the Terms of Use, Risk Disclosure and Privacy Policy once per wallet.
#before

Buying YES or NO

  1. Pick a side, then enter the USDC amount you want to spend.
  2. Check estimated shares, average price, price impact and the 1.50% fee breakdown.
  3. Approve USDC once for the router, then confirm the trade.

Slippage and minimum output

Slippage tolerance sets the minimum shares (or USDC on a sell) you will accept. If the price moves beyond it before your transaction lands, the trade reverts instead of filling badly. Pro mode lets you set the minimum output directly.

A very wide tolerance protects you from failed transactions but exposes you to a much worse fill.

Cashing out early

Selling back into the pool is how you exit before resolution. You receive USDC at the current curve price, minus fees. In a thin market the exit price can be materially worse than your entry.

Claiming after resolution

Once the outcome is final, winning positions are redeemed from your portfolio. Redemption is a transaction you sign; nothing is pushed to you automatically.

Reading the chart

The probability chart is built from on-chain Trade events, so it shows exactly what traders did, not an interpolation. Your own trades are marked on it when your wallet is connected.
