Never used cryptocurrency before? Don't worry. USDT and USDC are USD stablecoins that stay 1:1 equal to the US dollar (1 coin ≈ $1 USD, without Bitcoin's price swings).

If you don't have a supported credit card, you just buy a small amount of USDT or USDC on an exchange and send it to the checkout address. The whole process takes 4 simple steps:

Step 1: Register an Exchange App (~2 mins)

Pick one of the world's top two exchanges below and create an account:

After signing up, download the official mobile app and complete the 2-minute Identity Verification (KYC).

Step 2: Buy USDT or USDC (~3 mins)

  1. Open the OKX or Binance app and tap Buy Crypto → Express Buy (or P2P Trading).
  2. Choose USDT (or USDC).
  3. Enter the amount (Important: buy 1–2 USDT/USDC extra):
    • For example, if your product costs $19.99, buy 22 USDT.
    • The extra 1–2 USDT covers the small network fee when you send the payment in Step 4.
  4. Pay the seller using your preferred local payment method, then tap I Have Paid. Within 1–2 minutes, the USDT/USDC will arrive in your account.

Step 3: Place Your Order & Copy the Checkout Address (~1 min)

  1. On Dingyue, open the product you want (such as ChatGPT Plus or Claude Pro), click Buy Now, and enter your email address.
  2. On the Tariapay checkout page, select:
    • Coin: Choose USDT if you bought USDT, or USDC if you bought USDC.
    • Network: Choose BSC, Arbitrum, or Base (these networks confirm in 1–2 minutes and cost only a few cents in fees).
  3. The page will show a Deposit Address and the Exact Amount Due (e.g., 19.99). Copy the deposit address.

Step 4: Withdraw from the Exchange to Complete Payment (~2 mins)

  1. Open the OKX or Binance app and tap Assets → Withdraw → Select USDT (or USDC) → On-chain withdrawal.
  2. Paste the address you copied from the checkout page.
  3. Select the matching network: You must pick the exact same network you selected at checkout:
Network Selected at Checkout Network to Pick in OKX / Binance
BSC BNB Smart Chain (BEP20)
Arbitrum Arbitrum One
Base Base
  1. Check the “Amount Received” (Most Important Step!):
    • The exchange will deduct a small withdrawal fee (for example, 0.20 USDT).
    • Look at the “Amount Received” shown at the bottom of the screen—it must equal the exact checkout total.
    • Example: If the checkout asks for 19.99 USDT and the withdrawal fee is 0.20 USDT, enter 20.19 as the withdrawal amount so that the checkout receives the full 19.99 USDT.
  2. Tap Submit and complete the verification code.

All done! In 1–3 minutes, the checkout page will automatically update to Payment Confirmed and take you back to your order page. Make sure to bookmark your order page link to submit your account details and track activation.

FAQ

What are USDT and USDC? Do their prices swing like Bitcoin?
No. USDT and USDC are USD stablecoins that stay pegged 1:1 to the US dollar (1 USDT ≈ 1 USDC ≈ $1 USD). You can think of them simply as digital dollars.
Should I buy USDT or USDC?
Either one works—both are supported at checkout. For beginners buying via P2P or Express Buy, USDT usually has the most sellers.
Why should I buy 1–2 USDT/USDC more than the product price?
Because transferring crypto from an exchange to the checkout address costs a small network withdrawal fee (around $0.10–$0.50). Buying 1–2 extra units ensures you have enough to cover that fee.
What if the amount received at checkout is slightly short due to the withdrawal fee?
Always check the 'Amount Received' box on your exchange before submitting. If you accidentally sent slightly less, save your order link and contact us via the Support page.
