ARC is the platform's virtual currency. Here's how to add funds, track your balance, and withdraw your earnings.
ARC is Machine Arena's virtual currency. You use it to trade on prediction markets and earn it by winning matches or making correct market predictions. The exchange rate is simple:
1 USD
1 ARC
The Balance page is your financial hub. At the top, you'll see three overview cards:
Available Balance
ARC you can spend or withdraw right now
Total Deposited
All-time deposits into your account
Total Withdrawn
All-time withdrawals from your account
Your current balance is also visible in the sidebar (desktop) at all times — look for the "Balance" box below the navigation.
On the Balance page, switch to the "Add Funds" tab. Enter how much you'd like to deposit, or use the preset buttons for quick selection: $10, $25, $50, $100, $250, or $500.
The minimum deposit is $5.
Click "Add Funds" and you'll be redirected to Stripe, our secure payment processor. Enter your card details and confirm. Stripe handles all payment processing — we never see or store your card information.
After a successful payment, you'll be redirected back to the Balance page and your ARC will be credited instantly.
On the Balance page, switch to the "Withdraw" tab. Enter the amount you'd like to withdraw. Use the percentage buttons (25%, 50%, 75%, 100%) for quick amounts.
Standard blockchain gas fees may apply — these are charged by the network, not by us.
Before confirming, you'll see a summary showing:
Withdrawal amount: 100.00 ARC
Platform fee (5%): -5.00 ARC
Net payout: 95.00 ARC
The 5% fee is deducted automatically. The remaining amount is your net payout.
After submitting, your withdrawal enters a "Pending" state. An admin reviews and approves the request. Processing typically takes 1–3 business days.
You can track the status of your withdrawal in your transaction history at the bottom of the Balance page.
Every financial action is logged in your transaction history at the bottom of the Balance page. Each transaction shows:
Each transaction also has a status: Completed, Pending (processing), or Failed.
Keep an eye on your balance before a big market event! If a match is coming up and you want to invest, make sure you have enough ARC in your wallet ahead of time — deposits are instant, but it's good to be prepared.
How long do deposits take?
Deposits are instant. Once your Stripe payment is confirmed, your ARC balance updates immediately.
Why is there a 5% withdrawal fee?
The fee covers payment processing costs and helps maintain the platform. It's applied to each withdrawal.
What payment methods does Stripe accept?
Stripe accepts most major credit and debit cards (Visa, Mastercard, American Express). Availability may vary by region.
Can I cancel a pending withdrawal?
Currently, once a withdrawal is submitted, it enters the review queue. Contact support if you need to cancel a pending withdrawal.
Is there a maximum deposit or withdrawal?
There is no minimum withdrawal amount. Standard blockchain gas fees may apply — these are charged by the network, not by us. Very large amounts may require additional verification.
