Hi, I like the design! @soyrosa @cryptoctopus
What's the tech stack?
Since it deals with crypto and therefore in Apple's eyes it can be seen as a gambling App, it should be a fully native app in order to avoid Apple review issues in the future, you aware of that?
Meaning that technologies like Cordova/PhoneGap, React Native, Ionic may not work well for you in order to be compliant with their Guidelines.
You should therefore develop a fully native App or use Flutter. With the latter despite the App being written in Dart it gets compiled into native code so that works too! (and Flutter is pretty cool to work with)
Good luck!
The team uses Flutter :-)
