Setting up a withdrawal whitelist is one of the most effective steps you can take to protect your digital assets. By enabling this security feature on the OKX app, you ensure that funds can only be sent to pre-approved wallet addresses stored in your address book. This adds a powerful layer of protection—especially if your account is ever compromised—by blocking unauthorized withdrawals to unknown destinations.
In this guide, we’ll walk you through how to activate the whitelist, add verified addresses, understand 30-day verification rules, and make the most of advanced security settings like withdrawal blocking.
Why Use a Withdrawal Whitelist?
The withdrawal whitelist acts as a gatekeeper for your crypto transfers. Once enabled, every outgoing transaction must go to an address already saved in your address book. This means even if someone gains access to your account credentials, they won’t be able to send funds anywhere new without first adding and verifying a destination—which requires multi-factor authentication.
Key benefits include:
- Prevents unauthorized fund transfers
- Adds an extra layer of control over outgoing transactions
- Works seamlessly with 2FA and other security protocols

Step-by-Step: Enable Whitelist on OKX App
Follow these simple steps to set up and manage your withdrawal whitelist directly from the OKX mobile application.
1. Open the OKX App and Navigate to Withdraw
Launch the OKX app, tap on Assets > Withdraw.
Tip: You’ll find the Withdraw option clearly labeled on the Assets homepage.
2. Choose Your Preferred Withdrawal Method
Select your desired method—typically On-chain transfer for direct blockchain transactions.
3. Pick the Cryptocurrency to Withdraw
Choose the coin or token you want to send, then select On-chain as the network type.
4. Enter or Select a Saved Address
You can either:
- Paste a wallet address manually
- Or choose from your existing address book
If no suitable address is listed, tap Add Address to create a new entry.
🔍 Pro Tip: When adding an address, you can save it under a specific network (e.g., Ethereum, Tron) and use it universally for all tokens on that chain.
5. Select Your Preferred Address Type
Under Select Address Type, choose the appropriate format (e.g., ERC-20, BEP-20). This ensures compatibility and avoids lost funds due to mismatched networks.
6. Save as Verified & Confirm
Check the box to save the address as verified—this allows future withdrawals without repeated verification prompts. Then tap Save to complete.
Now, whenever you withdraw to this address, the process will be faster and more secure.
7. Activate Whitelist Protection
Go to Address Book Settings and toggle on:
- ✅ Whitelist Only: Restricts withdrawals exclusively to saved addresses
- 🔒 Block Withdrawals to New Addresses: Adds a 24-hour delay before any newly added address can be used
This dual-layer setting significantly reduces risk during potential account breaches.
Once enabled, any attempt to send funds outside your approved list will be blocked automatically.
Understanding 30-Day Verification for Whitelisted Addresses
A critical update to OKX’s security model involves time-limited verification periods for whitelisted addresses. Here's what you need to know:
When you verify a withdrawal address, it’s now valid for 30 days by default. To keep it active:
- You must make at least one withdrawal within each 30-day window
- If no transaction occurs, the verification expires
- Future withdrawals will require re-verification
Each successful withdrawal resets the clock—extending validity by another 30 days from the date of the last transfer.
Example:
You send funds on July 4, 2024 at 7:00 AM UTC → The verification remains valid until August 3, 2024 at 7:00 AM UTC.
If you don’t withdraw again before that time, you’ll need to re-authenticate the next time you send funds.
How Does This Affect Existing Verified Addresses?
All previously verified addresses have been transitioned into this 30-day rolling verification system automatically.
To maintain long-term access without recurring checks:
- Option 1: Wait for the 30-day period to expire, then re-verify permanently
- Option 2: Delete and re-add the address, selecting permanent verification
This gives users flexibility while encouraging active management of trusted destinations.
How to Set Permanent Verification
By default, new addresses are verified for 30 days. But you can opt for permanent status:
- While adding or editing an address, look for Change Verification Period
- Switch from “30 days” to Permanent
- Confirm with your 2FA code
Note: Permanent verification still requires full authentication during setup and cannot be bypassed.
👉 Maximize your account security with permanent address verification.
Frequently Asked Questions (FAQ)
Q: What happens if I disable the whitelist?
A: Once disabled, you can withdraw to any address—even those not in your address book. However, this increases exposure to unauthorized transactions. Always confirm changes using 2FA.
Q: Can I have both whitelist and 24-hour withdrawal block enabled?
A: Yes. Enabling both offers maximum protection: only approved addresses are allowed, and new ones require a full day before becoming active.
Q: Do I need to re-verify after 30 days if no withdrawal was made?
A: Yes. Inactivity causes expiration. Simply initiate a small test transaction before the deadline to extend validity.
Q: Is there a limit to how many addresses I can whitelist?
A: No strict limit exists, but only verified or recently used addresses will remain active under the 30-day rule.
Q: Can I use the same address for multiple cryptocurrencies?
A: Only if they share the same network (e.g., USDT and ETH on Ethereum). Always double-check network compatibility to prevent loss.
Q: What should I do if I lose access to a whitelisted wallet?
A: Remove the old address from your book and add your new one. Remember—new addresses may face delays if withdrawal blocking is enabled.
Best Practices for Managing Your Withdrawal Security
To get the most out of the whitelist feature:
- Regularly audit your address book
- Label addresses clearly (e.g., “Hardware Wallet,” “Exchange B”)
- Use permanent verification for core wallets you use often
- Keep 2FA active and secure
- Test small amounts when using an address after expiration
Security isn’t just about setup—it’s about ongoing maintenance.
