Before your first trade
- Connect a wallet on Arc Testnet, the interface prompts you to switch network if needed.
- Hold USDC on Arc. Gas on Arc is paid in USDC, so keep a small buffer.
- Read the market's rules tab, including the resolution source and timezone.
- Acknowledge the Terms of Use, Risk Disclosure and Privacy Policy once per wallet.
Buying YES or NO
- Pick a side, then enter the USDC amount you want to spend.
- Check estimated shares, average price, price impact and the 1.50% fee breakdown.
- 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.
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.

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

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.
