HAPI is an on- and off-chain solution that provides a diverse set of data on malicious and fraudulent activity within the Blockchain space. HAPI is subdivided into two parts: Protocol part which is essentially an on-chain publicly available and accessible database on malicious addresses, activity and can be accessed both via Smart Contracts as well as API, and off-chain part that allows both users and business to utilize a real-time monitoring and vetting system of both Token Smart Contracts (common vulnerabilities) and Malicious Addresses. HAPI also utilizes machine learning for off-chain data processing and aggregates data from public and paid data points to ensure the highest accuracy of risk representation.
