How to Transfer USDT from an Exchange to a Wallet: Step-by-Step Guide

Introduction

Transferring USDT from an exchange to a self-custody wallet is essential for secure long-term storage or decentralized finance (DeFi) interactions. This guide demonstrates how to move USDT via the Optimism network using OKX Exchange and its integrated Web3 Wallet, including troubleshooting gas fee issues.

Step 1: Create a Web3 Wallet

1. Open the OKX App and navigate to the Web3 Wallet section.
2. Click 【Create Wallet】 → 【Create Now】.
3. Set a 6+ character password (this is a login password, not a private key).
4. Confirm to complete wallet creation.

🔹 Pro Tip: The password can be reset via助记词 (recovery phrase), but losing both means irreversible asset loss.

Step 2: Backup Wallet助记词 (Recovery Phrase)

1. Choose Manual Backup (more secure than cloud backup).
2. Enter your password to view the 12-word助记词.
3. Write it down physically on paper—never digitally (no screenshots/cloud storage).
4. Verify the order by answering positional prompts (e.g., "What’s the 4th word?").

⚠️ Warning: Anyone with your助记词 controls the wallet. Store multiple copies securely.

Step 3: Transfer USDT from OKX to Web3 Wallet

1. In Web3 Wallet, click 【Receive】 → 【Quick Transfer from Exchange】.

2. Select:

   • Asset: USDT
   • Network: Optimism (OP)
3. Enter the amount (e.g., 50 USDT) and confirm the 0.15 USDT fee.
4. Authenticate and wait ~2 minutes for the transfer.

✅ Success Check: Your USDT balance will appear under the OP network in the wallet.

Step 4: Sending USDT from Wallet to Exchange

1. Click 【Send】 → Select USDT and paste the recipient address (or choose OKX’s auto-listed exchange address).
2. Enter the amount and proceed.

⛽ Gas Fee Issue: If prompted "Insufficient OP ETH for network fees":

• Buy ETH on OKX via Spot Trading (ETH/USDT pair).
• Transfer ETH to your Web3 Wallet via the OP network (repeat Step 3 with ETH).

Step 5: Receiving USDT from Other Exchanges (e.g., Binance)

1. In Web3 Wallet, click 【Receive】 → Select USDT and OP network.
2. Copy the deposit address or scan the QR code.

3. On the external exchange (e.g., Binance):

   • Withdraw USDT to the copied address.
   • Ensure the OP network is selected to avoid cross-chain losses.
