How to Deposit USDT via the OKX Mobile App
The OKX mobile application provides an intuitive interface for users to manage their crypto assets on the go. Follow these steps to deposit USDT using your smartphone:
- Open the OKX App and Navigate to “Assets”
Tap on the “Assets” tab at the bottom of the screen, then select [Deposit]. This will take you to the deposit center. - Choose USDT and Select “On-Chain Deposit”
Search for USDT or scroll to find it in the list. Once selected, ensure that On-Chain Deposit is enabled. The system will automatically display all supported networks for USDT (e.g., TRC20, ERC20, Omni). - Copy the Deposit Address or Save the QR Code
After selecting your preferred network (more on this later), you’ll see a unique deposit address generated by OKX. You can either copy this address or save the QR code for easy sharing. - Provide Required Information (Memo/Tag)
For certain networks like BSC or XRP, a Memo or Tag is required. Always double-check if this field is mandatory—entering it incorrectly may result in lost funds. - Initiate Withdrawal from Your External Wallet
Go to your external wallet or another exchange, start a withdrawal of USDT, paste the copied address, and choose the same network used on OKX. Confirm the transaction. - Wait for Blockchain Confirmation
Processing time depends on network congestion and confirmation requirements. Once confirmed, your USDT will appear in your OKX account under “Asset Overview” or “Deposit History.” - Security Reminder
Never share your private keys or seed phrases. Only use verified platforms and confirm URLs before entering sensitive information.
How to Deposit USDT via the OKX Desktop Website
For users who prefer larger screens or plan to make frequent trades, the desktop version offers enhanced functionality:
- Log In to Your OKX Account
If you haven’t registered yet, click [Sign Up] in the top-right corner and complete email and phone verification. - Complete Identity Verification (KYC)
To unlock full trading capabilities, go to Assets > Identity Verification and submit required documents. This step is essential for compliance and security. - Access the Deposit Section
Click on Funds > Deposit in the main menu. Choose USDT as the deposit currency. - Select Network and Account Type
Decide whether to deposit into your funding account or trading account, then pick the appropriate blockchain network (e.g., TRC20, ERC20). - Copy the Unique Deposit Address
OKX generates a new address for each deposit request. Double-check that the network matches your sending platform. - Complete Transfer from External Source
Paste the address into your sending wallet, verify all details—including network compatibility—and confirm the transfer. - Monitor Transaction Status
Track progress via transaction hash (TxID). Most deposits are credited within minutes, depending on network speed.

Understanding USDT Networks: TRC20 vs ERC20 vs Omni
Not all USDT tokens are created equal. While they all represent $1 USD in value, they operate on different blockchains—each with unique features:
USDT-Omni (Bitcoin Network)
- Origin: Launched in 2014, the original form of USDT.
- Address Format: Uses Bitcoin addresses.
- Fees: Requires BTC for miner fees; costs vary based on BTC network congestion.
- Speed: Slower processing times due to Bitcoin’s block time (~10 minutes).
- Best For: Large transfers where security outweighs speed concerns.
USDT-ERC20 (Ethereum Network)
- Launch: Gained popularity in 2018 alongside Ethereum’s rise.
- Fees: Paid in ETH (gas fees), generally stable but can spike during high demand.
- Speed: Faster than Omni, typically confirmed in under a minute.
- Best For: Medium-sized transactions requiring reliability and wide support.
USDT-TRC20 (TRON Network)
- Launch: Introduced by Tether on TRON in April 2019.
- Fees: Nearly zero transaction cost.
- Speed: Almost instant—often confirmed in seconds.
- Best For: Small, frequent transfers where low cost is critical.
⚠️ Important: These networks are not interoperable. Sending USDT-ERC20 to a TRC20 address will result in permanent loss unless recovered through customer support.
Choosing the Right Network: Expert Recommendations
| Use Case | Recommended Network |
|---|---|
| High-value transfers | USDT-Omni or USDT-ERC20 |
| Regular trading deposits | USDT-ERC20 |
| Fast, low-cost transfers | USDT-TRC20 |
Always match the withdrawal network with your deposit network on OKX.
What If My Deposit Isn’t Showing Up?
Don’t panic—delays happen. Here are common reasons and solutions:
1. Pending Blockchain Confirmations
OKX requires a set number of confirmations before crediting your account. Check your TxID on a blockchain explorer (like Tronscan or Etherscan) to monitor status.
2. Wrong Coin or Network
Sending ETH to a BTC address? That won’t work. Ensure both coin type and network match exactly.
3. Missing Memo/Tag
Some coins require additional identifiers. If skipped or entered incorrectly, funds may be stuck.
4. Used Smart Contract Address
Never send funds to a token’s contract address. Always use the personal deposit address provided by OKX.
5. Below Minimum Deposit
Each coin has a minimum threshold (e.g., 1 USDT for TRC20). Transactions below this amount won’t be processed.
6. Bundle Deposits
Avoid combining multiple small transfers into one outgoing transaction—it can confuse systems and delay processing.
If none of these apply, contact OKX support with your TxID, amount, and timestamp for assistance.
