Would be really cool to see it somehow integrated with India's RuPay, our alternative to Mastercard and Visa. RuPay has been pretty successful domestically lately, especially with support for UPI. International payments are supported via the Discover network but coverage isn't great because Discover isn't widely accepted.

It's been interesting to see just how far ahead India's consumer banking is. I can't think of any country that comes close. It's also interesting to see Europe moving in roughly the same direction. With the FTA and all, I hope these attempts at sovereignty turn into new ways to collaborate, rather than just isolate. Cooperation without dependence would be cool.
