In short: Use BCH to seamlessly pay anyone connected to India's UPI payment network: huge network of merchants + a number of other apps.
If I understood right they have a non-custodial BCH wallet that does the conversion on-the-fly. Their backend receives your 0-conf BCH and pays out INR using their payment system (UPI) and it all takes 5sec, merchant doesn't know you're paying in BCH.
Is this a proof of 0-conf power or what?
