How to Sell Crypto on OKX
Selling works similarly through the C2C marketplace:

Best Practices for Account Security
In crypto, self-custody means self-responsibility. Follow these steps to safeguard your assets:
✅ Enable Two-Factor Authentication (2FA)
- Use Google Authenticator instead of SMS where possible — it’s more secure.
- Avoid storing 2FA codes on cloud backups.
✅ Separate Your Devices
- Operation Device: Used for trading and wallet access (e.g., primary smartphone).
- Verification Device: Dedicated secondary device for receiving 2FA codes and emails.
🛡️ Never use the same Android phone for both operations and verification — malware could compromise both layers.
✅ Disable Unused Features
- Turn off API access if you’re not using bots or third-party tools.
- Set up an anti-phishing code under Security Settings.
✅ Stay Updated
OKX recently updated its iOS app (v6.71.1) to require email + authenticator code for withdrawals — removing reliance on SMS alone. Always keep your app updated to benefit from the latest security enhancements.
