If your large withdrawal is blocked by the system and you are asked to confirm that it was you who made the request, do not panic. This means OKX's "Large Withdrawal Protection" has been triggered. Its core logic is that the risk control system first pauses the withdrawal, then verifies whether the operator is the actual account owner through specified steps.

Why Was It Blocked? — Risk Control Logic
The reason for the block is usually that the large transfer triggered the system's risk control threshold. The platform marks such operations as high-risk, temporarily suspends the withdrawal process, and releases it only after the user completes identity confirmation.
How Exactly Do You Confirm It Was You?
According to the platform's standard process, confirmation usually involves a combination of the following:
Email or SMS verification code: This is the most basic step. After submitting the withdrawal request, the system will first ask you to enter the code sent to your bound email or phone to confirm that the operator has access to the account.
Two-factor authentication (such as Google Authenticator): If 2FA is enabled, after entering the verification code, you usually need to enter the dynamic code as well to further confirm the operator's identity.
Face recognition or video verification (for large amounts or high-risk cases): If the amount is particularly large, or the system judges the risk to be high, you may be required to perform face recognition, or record a video containing specified scripted phrases and upload it to prove that you are the one making the request.
Specific Steps in Different Situations
Situation A: The system shows "Under Manual Review"
[What to do]: Follow the on-page instructions and complete all available verification steps (verification code, 2FA, etc.), then wait for backend manual review.
[How to do it]: If the review takes a long time (from tens of minutes to several hours), check your email or in-app notifications for any requests for additional materials.
[Completion standard]: The page status changes to "Withdrawal Successful", or you receive an SMS/email notification.
Situation B: The system asks you to "Contact Customer Support for Verification"
[What to do]: Contact online customer support, explain the situation, and provide the required materials (such as screen recordings or face verification videos) as instructed by the support agent.
[How to do it]: Prepare the transaction hash (TxID) and a screenshot of the withdrawal record. This will help customer support quickly locate the issue.
[Completion standard]: After customer support confirms your identity, the block is lifted and the withdrawal continues to be processed.
Risk Reminders:
Do it yourself: All verification steps (especially face or video verification) must be completed by the account holder personally. Do not try to have someone else do it for you, otherwise you will not pass risk control.
Beware of "customer support" scams: When your withdrawal is blocked, do not click any "customer support links" or "accelerated withdrawal" links sent from unofficial channels. All operations should be completed within the official OKX app or website to prevent information leakage.

Verification Wrap-Up
After completing all verification steps, you can check the status on the "Withdrawal Records" or "Assets" page. If it shows "Completed" or "Successful", the block has been lifted and the funds are being processed. If the status remains unchanged for a long time, you can use the transaction hash (TxID) to check the on-chain status in a block explorer.
