Always verify the developer name and user reviews before installation.
Create Your OKX Account: Fast and Secure Registration
Follow these steps to set up your account with strong security from day one.
Step 1: Begin Registration
Open the OKX app and tap Register.
Choose between:
- Phone number registration (recommended for faster verification)
- Email registration
Enter your contact information and create a strong password containing uppercase letters, numbers, and special characters (e.g., OkxSecure#2025).
Complete the process by entering the SMS or email verification code.
Step 2: Complete Identity Verification (KYC)
To unlock full functionality—including higher deposit limits and withdrawal access—you must complete Know Your Customer (KYC) verification.
Navigate to:
Personal Center → Identity Verification
Upload clear photos of both sides of your government-issued ID and complete facial recognition. Most verifications are processed within 10–30 minutes.
Step 3: Enhance Account Security
Protect your assets with these essential settings:
- Enable Google Authenticator: Add two-factor authentication (2FA) for login protection.
- Set a fund password: A separate PIN required for withdrawals and trades.
- Turn on SMS alerts: Receive real-time notifications for all account activities.
These steps significantly reduce the risk of unauthorized access.

How to Deposit via Alipay: Step-by-Step
- Go to Assets → Deposit → Fiat Deposit
- Select Alipay as your payment method
- Enter the amount (minimum: 100 RMB)
- Copy the seller’s Alipay account shown in the app
- Make the transfer through your Alipay app
- Include the order number in the payment remarks
- Return to OKX and click Paid
- Wait for the seller to confirm and release funds (usually within minutes)
Ensure accuracy in the remark field—this is crucial for automated matching.
Buy USDT: Complete Guide for Beginners
After depositing RMB, you can instantly purchase USDT through OKX’s C2C (peer-to-peer) marketplace.
Using the C2C Trading Platform
- Tap Buy Crypto → C2C Trading
Search for USDT and filter offers by:
- Lowest price
- Highest completion rate
- Payment methods (select Alipay or WeChat)
- Choose a reputable seller with high ratings (>95%) and “Platform Certified” badge
- Enter the purchase amount and confirm
- Complete payment via your chosen method
- Click I’ve Paid, then wait for the seller to release USDT
Funds typically arrive within 15 minutes.
Understanding Fees
- C2C purchases: No direct fees—prices include a small premium set by sellers.
Spot trading (crypto-to-crypto):
- Maker fee: 0.08%
- Taker fee: 0.1%
Example: Buying 1,000 USDT via spot market incurs ~0.8–1 USDT in fees.
Avoid Common Pitfalls
- Price volatility: Use limit orders to lock in rates instead of market orders.
- Failed transactions: Double-check that payment remarks include the order ID.
- Scams: Only trade with highly rated, platform-verified sellers.

Risk Prevention Measures
- Never open suspicious links sent via message or email.
