Buying a card

1

Sign in

Sign in with X, Google or an email address. Your cards are tied to that account, which is how we know which ones are yours.
2

Choose an amount

Between 5and5 and 1,000. The card is loaded with exactly that amount.
3

Pay from your wallet

A QR code appears with the exact amount. Scan it with any Solana wallet, or copy the address and send manually. Pay in SOL or USDC.
4

Wait about a minute

The page follows your payment on its own: it confirms the transaction, converts it if you paid in SOL, and orders the card. You do not need to refresh.
5

Spend it

Your card number, expiry date and security code appear on screen and stay available in your account.

Paying in SOL vs USDC

Both work. The difference is what happens to the price. USDC is a dollar, so the amount you send is the amount you get. What the payment screen shows is what you pay. SOL moves. We quote the SOL amount when you create the order and include a small buffer, because the price can drift between the moment you see the QR code and the moment your transaction lands. If SOL moves in your favour, the surplus stays on your order.

If something goes wrong

Orders expire if no payment arrives in time. If you paid and the order did not complete, the payment is still recorded against your account — contact us with the order and we will resolve it. Do not send a second payment.
Your card details are never stored on your device. They are fetched fresh from the issuer each time you open the card, which is why you have to be signed in to see them.
