In Poland everyone uses Blik, recently even Revolut (a popular pan-EU neobank) started supporting it for transactions in Poland. It’s trusted, available for 10+y and generally a successful project.
I don’t think it ever tried expanding outside of Poland though.
When it comes to Wero—I’m not sure. My bank recently replaced “payconiq” with it, and I don’t see any benefits or new features and the app seems amateurish.
I guess the single market is not really “single” in the US sense.

The real benefit is "one to rule them all". It's so much more useful to have one single network that everybody uses even if the service doesn't have all the bells and whistles, than it is to have to use a patchwork of 1000 different networks even if they're stuffed with fancy features.

What app? In the Netherlands, where wero originated as iDeal, I've always used it via my bank's app. Isn't it how it's supposed to work?
