Cryptocurrency trading has become increasingly accessible, and platforms like OKX are at the forefront of this digital revolution. As one of the leading cryptocurrency exchanges globally, OKX offers a robust suite of tools for both beginner and advanced traders. This guide dives deep into essential aspects of using OKX—covering everything from understanding your OKX UID, setting up API keys, configuring margin modes, performing internal transfers, and leveraging advanced trading functionalities.
Whether you're exploring spot trading, futures contracts, or automated strategies, mastering these core features is crucial for a seamless and secure experience on the platform.
What Is an OKX UID?
An OKX UID (User ID) is a unique identifier assigned to every registered user on the OKX exchange. Think of it as your personal account number within the OKX ecosystem. It's used primarily when:
- Receiving internal transfers from other OKX users
- Verifying account ownership
- Setting up third-party integrations that require user identification
The UID ensures fast, secure, and fee-free transactions between users on the same platform, making it especially useful for traders collaborating with signal providers or managing multiple accounts.

How to Create an API Key on OKX
Application Programming Interfaces (APIs) allow external software to interact securely with your OKX account. They are essential for:
- Automated trading bots
- Portfolio tracking tools
- Copy-trading or "follow-trade" systems
- Real-time market data analysis
Creating an API Key via OKX Website
- Log in to your OKX official website.
- Navigate to the top-right menu and click on "API".
- Choose "Create API Key" or "Apply for V5 API".
- Enter a descriptive remark name (e.g., “TradingBot_Main”).
- Set permissions: Select read-only, trade, or withdrawal access based on need.
- Enable IP binding for enhanced security.
- Confirm via two-factor authentication (2FA).
🔐 Security Tip: Never share your secret key. Store it in a secure password manager or encrypted file.
Creating an API Key via OKX Mobile App
- Open the latest version of the OKX mobile app.
- Tap the menu icon (☰) in the top-left corner.
- Scroll down and select "API Management".
- Tap "Create API Key".
- Follow the same steps as above to configure permissions and security settings.
Once created, these API keys can be integrated into third-party applications such as algorithmic trading platforms or portfolio dashboards.
Configuring Single-Currency Margin Mode
If you're using copy-trading or automated trading tools like OKX Contract Signal Following Software, you may encounter the error:
"Only single-currency margin mode is supported."
To resolve this, you must switch your account’s margin mode:
On Desktop (OKX Website)
- Go to the Derivatives section.
- Select Futures Trading.
- Click on your profile icon or settings gear near the balance display.
- Choose "Account Mode" > "Single-Currency Margin".
- Confirm the change—note that open positions may affect eligibility.
On Mobile (OKX App)
- Open the Trading tab.
- Tap "More Settings" (usually represented by three dots).
- Find Account Mode and switch to Single-Currency Margin.
This unified margin system simplifies risk management by allowing cross-utilization of funds across different contracts within the same currency.
Performing Internal Transfers on OKX
Transferring assets between OKX users is fast, free, and highly efficient—especially useful for teams, family members, or paying for services directly in crypto.
Steps for Internal Transfer (Web & App)
- From your dashboard, go to Assets > Internal Transfer.
- Enter the recipient’s OKX UID.
- Select the token (e.g., USDT, BTC, ETH).
- Input the amount.
- Confirm with 2FA.
No network fees apply, and transfers are completed instantly.
