Korbit, a South Korean exchange, was fined approximately $2 million by the Financial Intelligence Unit (FIU) for insufficient anti-money laundering compliance. The investigation revealed significant vulnerabilities in the platform's transaction monitoring and customer due diligence mechanisms—approximately 22,000 suspicious transactions were not effectively identified, and some users were allowed to trade without completing KYC verification. After receiving the fine and official warnings, Korbit officially accepted the penalty decision and announced that it would not appeal. This incident serves as a reminder to the industry: building an anti-money laundering system is not only a legal requirement but also the foundation for the long-term operation of trading platforms. A robust customer identity verification process and continuous monitoring of transaction anomalies have become standard features for global exchanges. In line with international regulatory trends, compliance investment has become a mandatory course for crypto exchanges.
