Merging wallets and instant exchange API

[AKprisonER]

I tested wallets individually. Most of them has inbuilt exchange service like shapeshift, changenow, and changelly. But they are not working.

Also how to merge all the wallets variants into single app. I would like have a self hosted decentralized wallet. This is opensource one but not updated regularly and i am building one for my own. But hw can we merge this into single app.
