Step 1: Get a Wallet App There are many cryptocurrency wallet apps to choose from. Here, we use Trust Wallet as an example. You can choose to download it from the Apple or Google app stores, or use the browser extension. (Click the links below to download)
Apple Google Chrome
After downloading Trust Wallet, the next step is to follow the app’s instructions to create your first wallet (don’t forget to back up your mnemonic phrase to prevent loss).

Step 2: Purchase Cryptocurrency in the Trust Wallet App On the wallet homepage, click the “Deposit” button to enter the purchase page, then click the “Buy Cryptocurrency” button. Enter the fiat currency you want to use and the cryptocurrency you want to buy. Prices may fluctuate based on your region and purchase amount. Please note that this purchase step may require you to complete KYC. We recommend choosing USDT (BEP/Binance Smart Chain) for purchase because its transaction speed is very fast and fees are extremely low.
Choose Binance smart chain and buy this USDT


Step 3: Generate an Order on Our Website to Purchase Using Cryptocurrency

Step 4: Complete the Payment in Your Wallet App On the popped-up Nowpayments order page, select the cryptocurrency and network you wish to pay with (Note: this step must be correct). If you purchased USDT (BEP20) in step 2, then here you need to select USDT (and Binance Smart Chain/BEP20). Then, you need to copy the payment amount and address.
Note: Please confirm the network your purchased USDT belongs to. Sending to the wrong network will result in no receipt. Please carefully verify:
ERC: ETH network
TRC: TRON network
BEP: Binance Smart Chain/BSC
They have different ICONS. Please carefully distinguish the types you hold!

In the Trust Wallet app, select the cryptocurrency you need to pay, Carefully distinguish the types of USDT you hold. Different types cannot be transferred. then click “Send,” enter the address and amount you just copied. After completing the payment, you’re done!
Tips
The most common error causing payment failure is not selecting the correct cryptocurrency and network on the Nowpayments order page. Please be sure to select both the correct cryptocurrency and network. For example, if you select USDT on the BEP/BSC network and charge with USDT/ERC20, the order will get stuck.
Another common error is the order being stuck in a partial payment state, usually because the miner fee was forgotten during payment. (However, this usually does not happen with the Trust Wallet app or BNB, because Trust Wallet independently calculates miner fees, and BNB’s miner fees are very low and almost negligible.) But if you use other wallet apps, please ensure the actual payment amount (after deducting miner fees) matches the amount on the order page, otherwise your payment may get stuck.
If you encounter any payment issues, please contact our support via email and provide your payment information: screenshots, order ID and payment ID on the webpage, payment address on the webpage (case-sensitive), and the Tx hash of the successful transaction.
