Transaction monitoring Meaning

Transaction monitoring is a continuous process by which financial institutions, cryptocurrency exchanges, and other businesses observe and analyse transactions in real time or retrospectively to detect suspicious or illicit activity. Using rule-based algorithms and machine learning, monitoring systems flag transactions that meet certain risk criteria, such as unusually large transfers, rapid movements across jurisdictions, or interactions with sanctioned addresses.

Compliance teams then investigate these alerts to determine whether they represent money laundering, fraud, terrorist financing, or other illicit activities. In the cryptocurrency space, transaction monitoring also helps exchanges comply with know-your-customer (KYC) and anti-money laundering (AML) requirements, enabling regulators to trace funds to their source.

Transparent and robust monitoring builds trust with regulators and customers, while also protecting platforms from being used for criminal purposes.
