Digital asset security has become a top priority for users as cryptocurrencies grow in popularity for investment and daily transactions. One of the most critical moments in managing your crypto is during withdrawal—when your funds are most vulnerable. A single mistake or account breach can result in irreversible loss. To help safeguard users, OKX offers a powerful security feature: the withdrawal address whitelist.
This guide walks you through everything you need to know about enabling and using the address whitelist on OKX—where to find the setting, how it works, what happens when you modify it, and best practices to maximize protection. Whether you're a beginner or experienced trader, this tool is essential for securing your digital assets.

What Is an Address Whitelist? Why Use It?
An address whitelist is a security mechanism that restricts cryptocurrency withdrawals to only pre-approved wallet addresses. Once enabled, any attempt to send funds to an unlisted address—even if entered correctly—will be blocked by the system.
This adds a crucial layer of protection against:
- Account takeovers: Even if your login credentials are compromised, hackers can’t transfer funds to their wallets unless those addresses are already whitelisted.
- Human error: Prevents accidental transfers to incorrect or mistyped addresses.
- Unauthorized transactions: Acts as a second approval checkpoint, especially useful for high-value accounts or shared wallets.
Think of it as a digital vault: you decide which destinations your money can go to—and no exceptions are allowed without re-verification.
In today’s landscape of rising phishing attacks and social engineering scams, enabling the OKX withdrawal whitelist is one of the simplest yet most effective steps you can take toward proactive account security.
Where to Find the Whitelist Setting on OKX
You can set up your withdrawal address whitelist from either the web version or the mobile app of OKX. The process is straightforward and consistent across platforms.
How to Set Up on Desktop (Web Version)
- Log in to your OKX account.
- Click on your profile icon in the top-right corner.
- Select "Security Settings" from the dropdown menu.
- Navigate to "Withdrawal Address Management" or "Address Whitelist".
Click "Add Address", then enter:
- The recipient wallet address
- Select the correct coin and network (e.g., USDT on TRC20)
- Optional: Add a label or note for easy identification
- Confirm via SMS, email, or two-factor authentication (2FA).
After adding the address, make sure to enable the option:
“Only allow withdrawals to whitelisted addresses” — otherwise, the protection won’t activate.
How to Set Up on Mobile (OKX App)
- Open the OKX app and tap “Me” (bottom right).
- Go to “Security Center”.
- Tap on “Address Management” or “Withdrawal Whitelist”.
- Choose the currency and blockchain network.
- Enter the wallet address and add a memo if needed.
- Complete verification using your preferred method (Google Authenticator, SMS, etc.).
Once confirmed, the address will appear in your list of approved destinations.

Can You Modify or Disable the Whitelist Later?
Yes—you retain full control over your whitelist at any time:
- Add new addresses
- Remove outdated ones
- Temporarily disable the restriction
- Review activity logs
However, there's an important safety measure:
When you disable the whitelist or remove a frequently used address, OKX triggers a security cooling-off period, typically lasting 24 hours. During this window, all withdrawal functions are suspended.
This delay prevents malicious actors from disabling protections and immediately draining funds. It also gives legitimate users time to notice suspicious changes and respond before damage occurs.
🔒 Pro Tip: If you ever suspect unauthorized access, do not disable the whitelist. Instead, immediately secure your 2FA, change passwords, and contact support.
Frequently Asked Questions (FAQ)
Q1: Does the whitelist work for all cryptocurrencies?
Most major coins—including BTC, ETH, USDT (ERC20/TRC20), BNB, and others—are supported on popular networks. However, newly listed tokens or assets on experimental blockchains may not yet support whitelist functionality. Always check the available options under "Withdrawal Address Management."
Q2: What happens if I try to withdraw to a non-whitelisted address?
The transaction will be rejected automatically. You’ll receive an error message such as “Address not in whitelist” or “Withdrawal restricted.” No funds are deducted, and no fees are charged.
Q3: Can I use the same address for multiple coins?
Only if they share the same network. For example:
- A TRC20 USDT address can receive other TRC20 tokens.
- But you cannot send ERC20 tokens to a TRC20-only address.
Always double-check both coin type and network compatibility before adding an address.
Q4: Is there a limit to how many addresses I can add?
There is no fixed upper limit, but OKX may impose practical constraints based on account tier or risk profile. Most users find 3–5 trusted addresses sufficient for daily use.
Q5: Do I need 2FA to manage my whitelist?
Yes. Any change to your whitelist requires multi-factor authentication—via SMS, email, or authenticator app—to verify your identity and prevent unauthorized modifications.
Q6: Will enabling the whitelist affect depositing funds?
No. The whitelist only applies to outgoing withdrawals. You can still receive funds from any address without restriction.
Best Practices When Using the Address Whitelist
To get the most out of this feature while avoiding common pitfalls:
✅ Verify network compatibility first – Sending USDT via ERC20 to a TRC20-only wallet leads to permanent loss. Always confirm chain alignment.
✅ Test with a small amount – After setup, perform a test withdrawal (e.g., $1 worth) to ensure everything works as expected.
✅ Keep emergency access – Maintain at least one reliable backup wallet in your whitelist for urgent transfers.
✅ Avoid duplicates – Repeated entries increase confusion and potential errors during selection.
✅ Regularly audit your list – Remove old or unused addresses every few months to minimize exposure.
✅ Never share verification codes – Scammers often pose as support agents asking for OTPs or recovery keys.
Final Thoughts: Make Security a Habit
The OKX withdrawal address whitelist isn’t just for high-net-worth traders—it’s a fundamental tool for every user who values their digital assets. In an ecosystem where threats evolve daily, proactive defense beats reactive recovery every time.
By taking just five minutes to set up this feature, you dramatically reduce the risk of losing funds due to breaches or mistakes. Combined with strong passwords and 2FA, the whitelist forms part of a robust security trifecta.
Don’t wait until something goes wrong. Protect your portfolio now—before it’s too late.
