Securing your cryptocurrency assets is a top priority when managing digital wallets and exchange accounts. One of the most effective security measures available today is the withdrawal address whitelist—a feature designed to restrict fund transfers exclusively to pre-approved destinations. This guide provides a comprehensive walkthrough of how to enable, manage, and optimize the whitelist function on the web platform, ensuring maximum protection for your crypto transactions.
Whether you're new to account-level security features or looking to refine your existing setup, this article will walk you through every step with clarity and precision. Key topics include enabling the whitelist, adding and managing trusted addresses, adjusting confirmation delays, and understanding operational limitations.

What Is the Withdrawal Address Whitelist?
The withdrawal address whitelist is a security mechanism that restricts all outgoing transfers to only those addresses previously added and verified in your account. Once activated:
- You can only withdraw funds to whitelisted addresses.
- Attempts to send to unapproved or manually entered addresses will be blocked.
- If the feature is disabled, withdrawals to any address are permitted.
This layer of control significantly reduces the risk of unauthorized or accidental transfers—especially critical during high-value transactions or in environments prone to phishing attacks.

Additional protections include:
- A mandatory waiting period before a newly added address becomes active.
- Real-time notifications sent to your registered email or phone number for all whitelist-related actions.
- Admin review required for sensitive changes like shortening wait times or disabling the feature.
These safeguards ensure that even if an account is compromised, attackers cannot immediately redirect funds.
Who Can Use This Feature?
The whitelist function is available across multiple access points:
- HTX Web Platform: Full control over enabling, configuring, and managing whitelisted addresses.
- HTX Pro App (v6.4.5 and above): Mobile users can also manage their whitelist settings seamlessly.
However, it's important to note:
- The restriction applies only to manual withdrawals via web and app interfaces.
- API users are exempt from these rules and continue using their predefined withdrawal endpoints as configured in API settings.
This distinction allows traders and bots relying on automated systems to maintain operational continuity while individual users benefit from enhanced personal account security.
Step-by-Step Guide: Managing Your Whitelist (Web)
3.1 Enabling the Whitelist Function
To activate the withdrawal address whitelist:
- Navigate to the Withdrawal Page, then go to Withdrawal Address Management.
- In the top-right corner, locate the Whitelist Status Toggle.
- Click the switch to bring up the activation confirmation modal.
- Select your preferred activation delay—this determines how long a new address must wait before becoming usable (e.g., 1 day, 3 days).
- Confirm your choice and complete two-factor authentication (2FA) via SMS, email, or Google Authenticator.
Once enabled:
- All future withdrawals are restricted to approved addresses only.
- Any previously saved non-whitelisted addresses become inactive for withdrawals.
⚠️ Important: After enabling the whitelist, you cannot bypass it for emergency transfers unless you disable the feature—but this requires administrative approval.
3.2 Adding a Whitelisted Withdrawal Address
After activation, you can add new addresses in two ways:
Option 1: Add a New Address to the Whitelist
- Go to the Add Withdrawal Address section.
- Enter the destination wallet address and network details.
- Check the box labeled “Add to Whitelist” before saving.
- The address enters a pending state and will only become active after the preset delay.
If you do not check the whitelist box, the address remains a standard entry and cannot be used for withdrawals under whitelist mode.
Option 2: Promote an Existing Standard Address
- From your address list, find a previously saved but unapproved address.
- Click the “Join” button next to it.
- Complete 2FA verification.
- The address is now queued for activation after the current waiting period.
This flexibility allows you to gradually build a secure network of trusted destinations without re-entering known wallets.

3.3 Removing a Whitelisted Address
To revoke access from an active whitelisted address:
- Open the address list.
- Locate the target address.
- Click “Remove” and confirm the action.
Once removed:
- The address reverts to a standard (non-whitelisted) status.
- It can no longer receive withdrawals unless re-added to the whitelist.
Use this option when decommissioning old wallets or responding to potential exposure risks.
3.4 Canceling a Pending Whitelist Addition
If you’ve added an address by mistake and it hasn’t yet become active:
- Find it in the list (marked as “pending” or “awaiting activation”).
- Click “Revoke”.
- Confirm the cancellation.
The address will be downgraded to a regular saved entry and will not activate automatically.
This safeguard gives you full control during the grace period, minimizing irreversible errors.
3.5 Modifying the Whitelist Activation Delay
You can adjust the waiting time required before new addresses become active:
- Click the Set Activation Time button in the upper-right corner.
- Choose a new delay duration.
Behavior depends on your selection:
- Extending the delay (e.g., from 1 day to 3 days): Applies immediately after 2FA confirmation.
- Shortening the delay (e.g., from 3 days to 1 day): Requires submission for admin review. Processing time varies from minutes to several days depending on account type and risk profile.
📌 Note: Changes apply only to addresses added after the update. Existing pending addresses follow their original schedule.
During review periods:
- No further modifications to timing or whitelist status are allowed.
- Prevents rapid configuration changes that could indicate suspicious behavior.
3.6 Disabling the Whitelist Function
If you need to temporarily allow unrestricted withdrawals:
- While the whitelist is active, click the toggle again.
- Confirm your intent in the pop-up dialog.
- Submit for administrator审核 (review).
Disabling takes effect only after approval—timing varies by user tier and activity history.
After successful deactivation:
- You can withdraw to any address immediately.
- All previously whitelisted addresses lose their status and become standard entries.
- Re-enabling the feature later requires re-adding each address individually.
This design ensures that disabling the whitelist is never instantaneous—adding another barrier against malicious actors.
Frequently Asked Questions (FAQ)
Q: How long does it take to disable the whitelist?
A: Disabling requires manual review and may take anywhere from a few minutes to several days, depending on your account’s verification level and transaction history.
Q: Can I use API withdrawals while the whitelist is active?
A: Yes. The whitelist restriction applies only to web and mobile interface withdrawals. API-based transfers follow their own security protocols and are unaffected.
Q: What happens if I enter an incorrect whitelisted address?
A: Always double-check addresses before saving. If an error is caught during the waiting period, use the “Revoke” option. Once active, incorrect addresses should be removed and corrected versions added anew.
Q: Do I get notified when changes occur?
A: Yes. Every action—including enabling, adding, removing, or modifying settings—triggers an alert sent to your registered email or phone number.
Q: Can I shorten my activation time instantly?
A: No. Reducing the waiting period requires administrator approval for security reasons. Extending it can be done instantly with 2FA.
Q: Are there limits on how many addresses I can whitelist?
A: There is typically no fixed limit, but platform policies may impose practical caps based on account type or region.
Final Tips for Optimal Security
To maximize protection:
- Always enable 2FA before configuring sensitive features.
- Use unique, complex passwords and avoid sharing device access.
- Regularly audit your whitelisted addresses and remove unused ones.
- Keep recovery methods up-to-date (email, phone, authenticator).
