Well, at least Wero is already working in a bunch of countries...

It's a bit different, as Digital Euro will be a bit more "digital cash" and allow offline payments, and, IIRC, won't depend on your bank.

The bad part about Wero is, at least in some countries, it depends on your bank, and you need that banks app (and the bank needs to support it). I'm on Bizum, that's a similar system on Spain that's being joined to the Wero system (they started the partnership in February or so, but I don't know the progress of it or when will it be joined).
