Managing digital assets securely is a top priority for every crypto user. One of the most effective tools for protecting your funds on exchanges is the address whitelist feature. On OKX, this powerful security setting ensures that withdrawals can only be made to pre-approved wallet addresses—significantly reducing the risk of unauthorized transactions.
But what happens when you need to update your list? Specifically: Can you add a new address right after deleting an old one? And can you use it immediately for withdrawals? Let’s dive into how OKX handles these actions and what limitations exist.
Understanding the Address Whitelist on OKX
The address whitelist is a critical account protection mechanism. Here's how it works:
- You manually register trusted wallet addresses (like your cold wallet or another exchange’s deposit address).
- Once enabled, only addresses on this list can receive withdrawals from your OKX account.
- Even if someone gains access to your login credentials, they cannot send funds to arbitrary addresses unless those are already whitelisted.
This function is disabled by default. Users must actively enable it in their security settings. For anyone holding significant balances or long-term investments, enabling the whitelist is strongly recommended—it acts as a financial firewall.

Can You Add a New Address Right After Deleting an Old One?
Yes—you can immediately add a new address after removing an old one from your whitelist. OKX does not impose any waiting period or cooldown between deletion and re-addition.
Here’s the typical process:
- Go to your Account Security Settings.
- Navigate to Withdrawal Address Management.
- Select the address you want to remove and confirm deletion via two-factor authentication (2FA).
- Click “Add Address,” enter the new wallet address and a descriptive label (e.g., “Cold Wallet” or “Exchange Transfer”).
- Confirm with 2FA (via SMS, email, or Google Authenticator).
Once confirmed, the new address will appear in your whitelist instantly.
However—and this is crucial—instant visibility does not mean instant usability.
Is the Newly Added Address Immediately Usable for Withdrawals?
No. Despite being successfully added, the new address enters a mandatory 24-hour cooling period before it can be used for any withdrawal.
During this time:
- The address appears in your whitelist.
- It cannot be selected as a destination for fund transfers.
- The restriction applies automatically and cannot be bypassed, even with full verification.
This cooling mechanism is designed to prevent rapid address replacement during account compromise. For example, if a hacker gains temporary access, they won’t be able to swap out your withdrawal address and drain funds within minutes. Instead, they’d have to wait 24 hours—giving you ample time to detect suspicious activity and take action.
This rule applies universally:
- When adding a brand-new address
- After deleting and replacing an existing one
- During initial setup of the whitelist feature
Can You Have Multiple Whitelisted Addresses?
Absolutely. OKX allows users to maintain multiple whitelisted addresses, with flexibility across different cryptocurrencies.
You can:
- Set unique addresses for each coin (e.g., BTC → Cold Wallet A, ETH → Wallet B)
- Register multiple addresses for the same cryptocurrency (e.g., both your hardware wallet and a trading account)
- Use custom labels to organize purposes: “Primary Backup,” “Trading Fund Transfer,” “Gift Wallet,” etc.
Having several trusted addresses reduces the need for frequent changes, which helps avoid triggering potential system flags for unusual behavior.

Frequently Asked Questions (FAQ)
Q: How long do I have to wait to use a newly added address for withdrawal?
A: You must wait 24 hours after adding the address. This cooling period is mandatory and cannot be skipped.
Q: Does deleting an old address reset the cooldown for other addresses?
A: No. Removing an address has no impact on the status of other whitelisted addresses. Their cooldown periods (if applicable) remain unchanged.
Q: Can I bypass the 24-hour lock by disabling and re-enabling the whitelist?
A: No. Disabling the whitelist removes all restrictions temporarily but exposes your account to higher risk. Re-enabling it will require all newly added addresses to undergo the same 24-hour waiting period.
Q: What happens if I try to withdraw during the cooling period?
A: The system will block the transaction and display an error message indicating that the address is still under review or not yet activated.
Q: Are there limits on how many addresses I can add?
A: While there’s no publicly disclosed hard limit, OKX encourages responsible usage. Excessive additions or deletions may trigger additional verification steps.
Q: Does the cooling period apply to internal transfers within OKX?
A: No. The 24-hour rule only affects external withdrawals. Internal movements (e.g., funding your trading account) are unaffected.
Best Practices for Managing Your OKX Whitelist
To maximize both security and convenience, consider the following tips:
- Plan ahead: If you anticipate needing to withdraw to a new address, add it at least one day in advance.
- Avoid rapid edits: Frequent additions and deletions may raise red flags; use batch updates when possible.
- Use clear labels: Name each address meaningfully so you don’t accidentally select the wrong one during high-pressure moments.
- Enable strong 2FA: Combine Google Authenticator with SMS/email verification for layered defense.
- Keep backups: Note down your whitelisted addresses externally (in encrypted storage) in case of device loss.
- Review regularly: Audit your list quarterly to remove outdated or unused addresses.
Final Thoughts
Yes, you can delete an old address and immediately add a new one to your OKX whitelist—there’s no delay in registration. However, due to robust security protocols, every newly added address must pass through a 24-hour cooldown period before it becomes active for withdrawals.
This design prioritizes safety over speed, ensuring that even in the event of unauthorized access, attackers cannot swiftly redirect your funds. While it may seem inconvenient at times, this small delay offers substantial protection against one of the most common forms of crypto theft.

By understanding and working with these built-in protections—not against them—you enhance both control and confidence in managing your digital wealth on OKX.
