Brief Answer: When the system detects abnormal or high-risk activity, it will temporarily freeze the transaction for manual review. The review is usually completed within 24 hours, and there is no need to resubmit during this period.
Common Trigger Scenarios
| Scenario | Trigger Reason |
|---|---|
| Large Withdrawals | Withdrawal amount exceeds the account’s usual activity range |
| First Withdrawal to a New Address | Withdrawal to an external address that has never been used before |
| Login from a Different Location / New Device | IP address or device fingerprint significantly differs from historical records |
| High-Frequency Trading in a Short Time | Operation pattern resembles automated scripts |
| Abnormal Source or Destination of Funds | Involves suspicious on-chain addresses |
| KYC Information Does Not Match Behavior | For example, declared country does not match login IP over a long period |
Risk control review is a protection mechanism and does not mean there is a problem with your account.
What You Can Do During the Review
- ✅ Keep your account logged in normally, avoid switching devices or changing IP addresses (this will extend the review time)
- ✅ Keep your registered email/phone accessible, customer support may contact you for verification
- ✅ Use other unrestricted functions normally (such as viewing market data or checking historical orders)
- ❌ Do not repeatedly submit the same transaction, it will be flagged as abnormal
- ❌ Do not trust any "accelerated review" channels, these are common scams
- ❌ Do not lend your account to others to operate on your behalf
After the Review is Completed
You will be notified of the review result through the following methods:
- System internal message
- Email notification (please check your spam folder)
- App push notification (if enabled)
Approved: The original operation will be automatically restored without needing to redo it manually.
Not Approved: The system will explain the reason and guide you to provide additional materials or change your operation method.
How to Reduce the Chance of Being Flagged by Risk Control
- Complete KYC identity verification: Unverified accounts are more likely to trigger risk control
- Maintain a stable login environment: Try to use the same device and network consistently
- Make a small test withdrawal before a large withdrawal: This helps the system establish "trust" for the address
- Avoid multiple large transactions within a short period
How Long Does It Take to Complete
| Risk Control Type | Typical Review Duration |
|---|---|
| General Risk Control | A few minutes to 1 hour |
| Withdrawal Risk Control | Usually within 24 hours |
| Compliance Review Involved | 1–3 business days |
| On-Chain Anomaly Involved | Depends on investigation; may take longer |
If the review takes more than 72 hours without a result, please submit a ticket through the Help Center including your account UID and the time the trigger occurred. Do not contact "customer service" through any unofficial channels to speed up the process.
