There are many countries that are working on their own CBDCs, but the vast majority of them are still in the proof of concept phase, Turkey, Sweden, Thailand, Ukraine, and Jamaica are some of those countries. Above these countries (in terms of development) is the United States, which, although it already has several tests on the table, is still debating which is the best software to use. And number 1 goes to China, which has been testing its digital Yuan for months with a few million citizens.
