How to Deposit Cryptocurrency into Your OKX Account
If you already own digital assets on another exchange or wallet, you can transfer them to OKX for trading or staking.
Step 1: Generate a Deposit Address
- Log in to OKX and go to Assets > Deposit.
- Search for the cryptocurrency you wish to deposit (e.g., BTC, ETH).
- Select the correct network (e.g., Bitcoin for BTC; ERC-20 for ETH).
- Copy the deposit address or scan the QR code.
Step 2: Initiate Transfer from External Wallet
Go to your external wallet or exchange:
- Open the Withdraw/Transfer section.
- Paste the OKX deposit address.
- Double-check that both the coin type and network match exactly.
- Enter the amount and confirm transaction (include sufficient gas fee if applicable).
Step 3: Wait for Confirmation
Most deposits require several blockchain confirmations before appearing in your OKX balance. You can track progress under Deposit History.
🔍 Example: Sending USDT via TRON (TRC-20) network? Ensure you select “TRC-20” when generating the deposit address on OKX. Mismatched networks may result in permanent loss of funds.
