Hi guys!
Explain how it will work a currency exchange on your gadgets? Do you plan to create your own exchange service or maybe you will use already known exchange services?
XZEN protocol is based
on blockchain Graphen. In order ensure the implementation of transactions
in the networks of Ethereum, Bitcoin and other existing crypto currencies,
this protocol has specialized gateways that allow operations in various
blockchain networks. Also, to work with third-party services (exchanges,
exchange services, storage services for IDs), XZEN protocol includes an open
API suitable for the individual needs of XZEN members. At the same time, all
data transmitting is encrypted, whereas private keys are never transmitted
and reliably protected inside the «cold» device.
From Whitepaper. They are going to use API from different exchanges. It's easy.
