I have a project which is working fine with stripe.
I did it with Expo and now I need to change the payment into Briantree because Stripe is not supporting Venmo.
I already ejected the project into bare React Native project.
So what I need is to install React Native braintree library and implement the Venmo p2p payment.
This project has no back-end.
All should be done with Firebase and Cloud Functions.
Ping me if you have any questions.
