Getting Started: Identity Verification
Before buying or selling USDT (commonly called "U") on OKX:
Complete LV2 Verification:
- Tap the profile icon in the top-left corner.
- Submit required documents for identity authentication.
- Upgrade to LV3 for higher transaction limits.
Two Entry Points for Transactions
Quick Buy/Sell:
- Allows instant purchases with bank cards/Alipay/WeChat Pay.
- Risk: Random merchant matching may expose you to unverified funds.
C2C Trading (Recommended):
- Direct peer-to-peer transactions with vetted merchants.
- Lower risk of encountering "black U" (illicit funds) or frozen accounts.
Setting Up Payment Methods
Step 1: Add a Bank Account
- Navigate to C2C → More → Payment Methods.
- Select Bank Card (lowest fraud risk).
- Use a dedicated card (not your primary salary/loan card).
- Avoid Alipay/WeChat for high-frequency crypto trades.
Step 2: Bank Selection Guide
| Tier | Recommended Banks | Notes |
|---|---|---|
| 1 | Chouzhou Bank, NetBank | Crypto-friendly, low triggers |
| 2 | ICBC, Bank of China, etc. | Stable but higher scrutiny |
| 3 | Commercial/City Banks | Higher risk of freezes |
Pro Tip: Use the card for 1 week of regular spending before trading to generate legitimate transaction history.
