To that end, the regulator will involve fintech companies, payment firms, and other organizations. In addition, it will examine micropayments and the use of CBDC in public services. The ECB has also opened applications for a new stage of its digital euro innovation platform. The regulator has divided the program into practical testing of payment functions and workshops on the future use of CBDC. The experimental phase will run from January to June 2027. Project participants will develop prototypes of electronic receipts, multiparty transactions, and other new user-interface features. The digital euro could be launched in mid-2029, provided the necessary legislative measures are adopted.
