South Korea's National Tax Service has initiated a tender for the procurement of cryptocurrency transaction tracking software, with a budget of approximately 146.5 million won ($99,500). The software aims to enhance the monitoring of tax evasion related to virtual assets. It is designed to support real-time monitoring of on-chain transactions, visualize fund flows between addresses and exchanges, and assist in investigating concealed assets, cross-border tax evasion, and undeclared gifts. This move is part of South Korea's efforts to strengthen regulatory capabilities ahead of the implementation of crypto taxes in 2027.
