Sandbox & Test Cards
The Mintos.Pro sandbox environment lets you test ARThash purchases and payment flows using test credit cards. No real money is charged. This is ideal for developers, testers, and users who want to explore the payment system before making real transactions.
What is Sandbox Mode?
Sandbox mode is a testing environment that simulates real payment processing without moving actual funds. When the platform is running in sandbox mode, all Stripe payment transactions use test infrastructure. You can freely test purchasing ARThash credits, subscribing to content, and all other payment features.
Info
When sandbox mode is active, you will see a "SANDBOX MODE" indicator on payment screens. All transactions made in sandbox mode are marked as test transactions and will not appear on your real bank statement.
Test Card Numbers
Use these test card numbers to simulate different payment scenarios. For all test cards, you can use any future expiry date (e.g., 12/30) and any 3-digit CVV (e.g., 123).
Successful Payment Cards
4242 4242 4242 4242Visa â Always succeeds. Use this for testing normal purchase flows.
4000 0025 0000 3155Visa â Always succeeds with 3DS authentication. Use this to test the 3D Secure verification step.
5555 5555 5555 4444Mastercard â Standard test card for successful payments.
3782 822463 10005American Express â Standard test card for successful payments.
Declined Payment Cards
4000 0000 0000 0002Visa â Always declined. Use this to test error handling and failed payment flows.
Test Card Rules
- Expiry date: Use any date in the future (e.g., 12/2030)
- CVV: Use any 3-digit number (e.g., 123)
- Cardholder name: Use any name
- Address: Use any valid address format
How to Test Payments
Navigate to ARThash
Go to the ARThash wallet page and click "Buy ARThash" to start a purchase.
Enter Amount
Choose the amount of ARThash you want to purchase. Remember: 100 ARThash = 1 EUR.
Enter Test Card
In the Stripe payment form, enter one of the test card numbers above with any future expiry date and any 3-digit CVC.
Complete Payment
Submit the payment. For the 3DS test card, you will see a simulated authentication page â simply confirm it.
Check Balance
After a successful test payment, your ARThash balance will be updated (in sandbox mode, these are test credits).
Important Notes
Warning
- Sandbox transactions do not charge real money from any bank account.
- Test ARThash credits earned in sandbox mode may be reset when the platform switches to production.
- The payment provider (Stripe) processes sandbox payments separately from real transactions.
- If you encounter issues with test payments, contact support with the transaction ID.
