Method 1: Buy USDT with Fiat Currency
The easiest way for beginners to acquire USDT is by using fiat currency such as USD, EUR, or CNY through bank transfers, credit cards, or local payment methods like Alipay (availability varies by region).
Step-by-Step Guide:
- Open the OKX App or Website
Log in to your account. If you don’t have one yet, registration takes just a few minutes. - Navigate to “Buy Crypto”
Tap on "Buy Crypto" > "Quick Buy", then select USDT as the target coin. - Enter Amount & Payment Method
Choose your desired amount and preferred payment method (e.g., bank transfer, card). Click “Instant Pay” to proceed. - Complete Verification & Payment
You may be prompted to complete identity verification (KYC), depending on your region and transaction size. Follow the prompts and complete the payment. - Receive USDT in Your Wallet
Once confirmed, USDT will typically arrive in your OKX account within 2–30 minutes.
⚠️ Note: Blockchain congestion or third-party service delays may affect processing times. For immediate assistance, contact OKX customer support directly from the app.
Method 2: Deposit USDT from Another Wallet
If you already own USDT in an external wallet (like Trust Wallet, MetaMask, or another exchange), you can easily transfer it to your OKX account using the on-chain deposit feature.
Step-by-Step Guide:
- Go to “Assets” > “Deposit”
In the OKX app or web platform, navigate to the Assets section and select Deposit. - Select USDT and Network
Choose USDT as the cryptocurrency and pick the appropriate blockchain network (e.g., TRC20, ERC20, BEP20).
🔍 Pro tip: Use TRC20 for lower fees and faster confirmation. - Copy Deposit Address
OKX will generate a unique deposit address. Double-check the network compatibility—sending via the wrong chain could result in permanent loss. - Send from Your External Wallet
Open your external wallet, paste the address, select the same network (e.g., TRON for TRC20), and confirm the transaction. - Wait for Confirmations
The deposit time depends on network traffic but usually takes under 15 minutes. You can track progress under Deposit History.

Select the cryptocurrency you want to exchange (e.g., BTC) and set USDT as the receiving currency. - Review Exchange Rate & Fees
The rate updates in real-time. A small trading fee applies, but slippage is minimal due to high liquidity. - Confirm the Swap
Tap “Exchange” to complete the transaction. The converted USDT will appear in your spot wallet immediately. - Check Swap History
