👉 Discover how easy it is to start buying USDT with RMB today.
Step 1: Download and Install the OKX Mobile App
To begin, you'll need to install the official OKX app. The mobile platform provides full access to trading features, account management, and P2P purchases — all optimized for smooth performance on smartphones.
While the original article includes third-party download links, we recommend visiting only the official OKX website for security. You can safely download the app by searching “OKX” in your device’s app store or navigating directly to the official site.
For iOS users: If you're using an Apple ID registered outside mainland China, you may find the app available directly in the App Store. Otherwise, consider switching to a non-mainland Apple ID to access it.
For Android users: APK downloads are supported via the official OKX site, ensuring authenticity and protection against malware.
Once installed, open the app and proceed to registration.
Step 2: Register and Log In to Your OKX Account
Creating an account on OKX is quick and straightforward:
- Open the OKX app.
- Tap "Sign Up" and enter your email address or phone number.
- Create a strong password and complete the verification process.
- Once registered, log in securely.
After logging in, you’ll be prompted to complete identity verification (KYC). This step is essential for enabling higher withdrawal limits and unlocking advanced trading features. Simply follow the in-app instructions to upload required documents, such as a government-issued ID.
Completing KYC not only enhances security but also builds trust within the P2P marketplace — crucial when buying digital assets with RMB.

Step 3: Navigate to the P2P Trading Section
Once logged in and verified, return to the OKX homepage within the app. Look for the "Buy Crypto" section — typically located at the bottom left corner of the screen — and tap on it.
From there, select USDT as the cryptocurrency you wish to purchase. The platform will automatically display a list of available sellers who accept RMB as payment. Each listing shows key details such as:
- Exchange rate (CNY per USDT)
- Minimum and maximum purchase limits
- Accepted payment methods (e.g., Alipay, WeChat Pay, bank transfer)
Choose a seller with high ratings, fast response times, and a preferred payment method like Alipay for convenience.
Step 4: Complete Your First USDT Purchase
Here’s how the transaction works:
- Enter the amount of RMB you want to spend or specify how many USDT you’d like to buy.
- Select your preferred payment method (Alipay is widely accepted).
- Review the order details carefully.
- Click “Buy USDT” to initiate the trade.
At this point, OKX will hold the seller’s USDT in escrow — protecting both parties during the exchange.
Next, follow the on-screen instructions to transfer the RMB amount to the seller’s designated account (via Alipay or another supported method). After making the payment, return to the app and click “I have transferred the funds” to notify the seller.
Once the seller confirms receipt, OKX releases the USDT to your account instantly. The entire process usually takes just minutes.
⚠️ Always communicate through OKX’s internal messaging system and never share personal information outside the platform.
