For Web and Mobile Apps

If you want to power your web or mobile app with bitcoin and want to offer payments directly in the app, have a look at the Alby NWC Wallet API. It allows native payment experiences for users. As a web and mobile developer, you can entirely focus on your app. Alby covers your back and does the payment processing for you.
