I recently spoke with David Gold who is the CEO of Dapix who are currently building out the FIO protocol.  Dapix is revolutionizing inter-wallet operability with the FIO Protocol. 

They are partnered with companies like Binance, Coinomi, Edge, Shapeshift, Bitcoin.com, Guardowallet, Atomic wallet, and many more.  The Foundation for Interwallet Operability (FIO) is a consortium of leading wallets, exchanges, and crypto payment processors supporting the FIO Protocol. FIO Members are early supporters who intend to integrate the protocol into their respective products and provide assistance/guidance in its direction.
