How Do You Buy Cryptocurrency?
If you do not yet own any cryptocurrency, your wallet offers several convenient ways to purchase crypto with fiat currency. The most popular options are OTC (Over-the-Counter) and P2P (Peer-to-Peer) trading. Each method has its own advantages, so you can choose the one that best fits your needs.
Features and Advantages of OTC Purchases
The OTC feature gives users a fast, compliant way to exchange fiat for crypto. It supports over 50 fiat currencies, including USD, EUR, JPY, KRW, and VND, allowing you to buy major stablecoins like USDT and USDC, as well as leading tokens such as BTC and ETH.
The wallet platform aggregates multiple trusted OTC providers, offering the following advantages:
- Speed and Convenience: Unlike traditional centralized exchange OTC channels, wallet-integrated OTC lets you complete exchanges instantly, without lengthy registration or verification
- Flexible Limits: No limit on transaction amounts, so you can make both small trial purchases and large trades
- Secure Funds: Partner OTC platforms undergo strict vetting to ensure compliant and safe funding sources
- Easy Operation: Ideal for users entering Web3 for the first time, lowering the barrier to entry
Step-by-Step: Buying Crypto via OTC
Here’s how to buy cryptocurrency using OTC:
- Open your wallet app and click the "Buy" button on the right; select "Buy crypto" from the menu
- On the next screen, set your preferences:
- Select the cryptocurrency you want to buy
- Choose the relevant mainnet (e.g., ERC20, TRC20)
- Select your fiat currency
- Pick a payment method (typically credit or debit card)
- For example: Use USD to buy USDT on the ERC20 network
- Click "Go to Moonpay pay" or select another OTC provider, then follow the prompts to complete identity verification and enter payment details
- Pay using your credit card or another supported method
- Once you submit your order, your purchased crypto will typically arrive at your wallet address within minutes
Note: First-time OTC users may need to complete KYC (identity verification). Prepare your ID documents and required materials. After approval, future purchases will be easier.
Buying Crypto via P2P Trading
P2P is another popular way to buy crypto, supported by partner exchanges. P2P transactions let you trade directly with other users and often offer more payment options, such as bank transfers, Alipay, WeChat, and more.
P2P Purchase Process:
- Open the wallet app, click "Buy" on the right, and choose "P2P trading"
- On the next screen, select the token you want and browse the available P2P merchant list
- Choose a merchant based on price, payment method, and transaction limits, then click "Buy"
- If you’re new to the platform, register an account with the partner exchange
- Complete KYC verification (usually requires uploading your ID and facial recognition)
- Once verified, proceed with your purchase
- Pay the merchant as instructed and confirm your payment on the platform
- After the merchant confirms receipt, they release the crypto, and you’ll receive it in your wallet
P2P Trading Tips:
- Trade with reputable merchants who have high transaction volumes
- Follow platform rules strictly; do not contact merchants outside the platform
- Include the order number or specified remarks when making payments
- Keep your payment receipts to provide proof if disputes arise
How Do You Transfer Crypto to Your Wallet?
If you hold cryptocurrency on other platforms, you can transfer those assets to your wallet address. While the process is straightforward, pay close attention to key details to keep your assets secure.
Detailed Transfer Procedure
For example, to transfer USDT on the Ethereum network:
- In your wallet app, tap "Receive"
- Select the token and the corresponding mainnet
- Important: The transfer and receiving networks must match (e.g., both ERC20 or both TRC20)
- If you use different networks, assets will be permanently lost and are unrecoverable
- Get your receiving info:
- Share your receiving QR code so the sender can scan and transfer
- Or copy your address and paste it into the recipient address field of the sending platform
- Enter the recipient address on the sending platform:
- Paste your copied address into the recipient field
- Double-check the address: Verify every character for accuracy
- Watch out for clipboard hijacking; always confirm your address wasn’t altered after pasting
- Enter the transfer amount and review the transaction fee
- Submit your transfer and wait for blockchain confirmation
Transfer Security Best Practices
To maximize asset safety, follow these guidelines:
- Small Test Transfers: When sending to a new address, transfer a small amount first to confirm before sending larger sums
- Batch Transfers: For large transfers, split the amount into several transactions to lower risk
- Address Verification: Always check the recipient address carefully before each transfer, especially the start and end
- Network Confirmation: Ensure that both sender and recipient use the same mainnet to avoid asset loss
- Save Records: Keep the transaction hash (TXID) for future reference and tracking
- Network Status: Transfers may take longer during congestion; be patient and avoid resubmitting
Common Mainnet Types Explained
Different cryptocurrencies support various mainnets. Knowing the mainnet types helps you choose correctly:
- ERC20: Runs on Ethereum, offers moderate speed and higher fees
- TRC20: Runs on TRON, delivers fast transfers and lower fees
- BEP20: Runs on Binance Smart Chain, with fast speed and moderate fees
- Native Mainnet: Such as the BTC and ETH mainnets, which are the original blockchains for their respective coins
How Do You Add Mainnets and Tokens?

- Search for the mainnet by name
- Browse the mainnet list shown
- Once you locate the mainnet, tap the "+" icon next to it

How to Add Tokens
After adding a mainnet, you can add specific tokens on that network to display in your asset list:
