KYC Verification

Background and Importance of KYC

KYC (Know Your Customer) is a widely used user identity verification mechanism in the global financial system. In digital asset platforms, implementing KYC is not only a crucial step to comply with regulations and ensure platform legality but also an essential measure to secure account assets, combat money laundering, fraud, and identity theft.

To systematize identity verification and implement layered protection, the platform adopts a “Basic Verification + Advanced Verification” two-tier KYC mechanism, combined with robust anomaly detection and risk control strategies. This helps identify user risks from the outset and improves overall account security and credibility.

Status and Restrictions for Unverified Users

Users who have not completed any KYC verification remain in a restricted account state, with only limited browsing and basic operations permitted.

Restrictions for unverified users include:

  • Unable to perform any withdrawals

  • Fiat trading and deposits disabled

  • Limited permissions for certain contract trading

  • Ineligible for specific platform events or airdrop tasks

  • Withdrawal limits set to the minimum, with no option to raise limits

Prompting and Display

  • Reminders displayed on home, assets, withdrawal, and other key pages after login

  • Backend configurable messages, styles, and entry buttons

  • Targeted prompts based on user country, device, or registration channel

Basic Verification Rules

Applicable Users

  • Suitable for users from non-high-risk countries

  • Users from Mainland China (CN) and the United States (US) cannot undergo basic verification and must proceed directly to advanced verification

Accepted Document Types

  • Only passports are accepted

  • Other IDs such as national ID cards or driver’s licenses will be automatically rejected

Verification Logic (Key Points)

  • Submitted names must be in recognizable format without special characters or errors

  • Passport number format errors cause failure

  • Duplicate passport numbers already used on other accounts are rejected

  • A behavioral CAPTCHA (e.g., GeeTest) must be passed before submission; failure blocks the process

  • Once basic verification info is approved, it cannot be modified without advanced verification or manual appeal

Advanced Verification Rules

Purpose

Advanced verification is for users seeking higher privileges (e.g., large withdrawals, fiat trading, contract trading) or from high-risk regions and represents the core KYC step.

Required Submissions

  • Basic information: full name, nationality, ID number, date of birth

  • Valid ID photos (passport, ID card, or driver’s license as per country requirements)

  • Selfie holding the ID to verify identity consistency

  • Strict photo format and content requirements for system review

Common Reasons for Rejection

  • Mismatch between submitted data and photo content

  • Use of ID numbers or names already registered on other accounts

  • Incorrect photo formats (non-JPG/PNG/JPEG)

  • File size exceeding 10MB limit

  • Blurry photos, facial occlusion preventing AI recognition

  • Incorrect upload order (e.g., mixing ID photo and selfie)

  • Cluttered background or obscured ID info

  • Expired or unofficial scan copies

Review Process

  • Automatic comparison of submitted info and ID images

  • Use of OCR, facial recognition, and image quality checks

  • Multiple failures allow manual review resubmission

  • Clear failure reason feedback to help users correct issues

Post-Verification Information Management

Information Locking

  • After passing basic verification, key info (name, ID type, ID number) cannot be changed unless advanced verification or an appeal is completed

  • All verification records are logged for audit and risk control

Failure Feedback

  • Detailed failure reasons provided (e.g., “Invalid photo format,” “Data mismatch,” “File too large”)

  • Multi-language prompts with guidance to retry or contact support

Risk Control and Login Management

To enhance KYC security, the platform also deploys the following auxiliary risk control measures:

  • Login Behavior Monitoring: Logs IP, device ID, timestamps; alerts on suspicious logins

  • Identity Verification Rate Limiting: Limits repeated failed attempts; flags suspicious multi-account registrations

  • Fraud Detection: Uses blacklist databases, device fingerprinting, and geo-location checks to identify risks

  • Risk Thresholds: Triggers secondary verification or forced advanced KYC based on risk patterns

Friendly Reminder

Dear user,

KYC verification is not only a key compliance step but also your first line of defense to secure your account and assets. We sincerely remind you to:

  • Complete advanced verification early to unlock all platform features such as withdrawals, fiat trading, contract permissions, and airdrop participation.

  • Carefully check all submitted information and documents to avoid rejection due to detail errors.

  • Follow system guidance for corrections or seek manual review support if needed.

  • Monitor login history regularly and promptly address any suspicious activities to enhance account protection.

We are committed to safeguarding your account through continuous monitoring and risk control.
