How to use delta Cash?

Could you please explain how exactly does one go about using delta Cash? I'm quite intrigued by its potential but I'm not entirely sure of the steps involved. Is it a straightforward process, or are there specific steps that need to be followed? Also, what kind of transactions can be facilitated using delta Cash? Is it mainly focused on cryptocurrency transactions, or can it be used for other financial activities as well? I'd appreciate any clarification you could provide on this matter.
