Does anybody know how i would go about putting a 'wallet' in my app for user to deposit money?

Question

I am developing an app but quite new to it and this seems a bit beyond my reach so far. Any guidance would be appreciated.

Answer 1

I would use Stripes API an online payment processing.

There is a lot to know about it and how to use it.
