Part 7/10:
Following the launch, major banks have begun testing the system through "proof of concept" cases—experimental scenarios to validate operational functionality before widespread deployment. Although specific participating banks have not yet been publicly identified, the scope includes issuing and circulating CBDCs and stablecoins, as well as using the UDPN as a payment gateway for e-commerce.
Plans for further proof-of-concept tests, scheduled to include various real-world use cases like online shopping transactions, indicate a comprehensive push towards integrating this network into everyday financial activities.
