 ComTracker is designed to uncover connections between Ethereum addresses. In its initial version (v1), users can input two Ethereum addresses to identify all transactions between them, including intermediate addresses ( in the application marked as depth 2). The application provides detailed information about the transaction time, the amount of cryptocurrency, and the type of cryptocurrency sent.
