Absolutely! We plan to run on the Ethereum blockchain (initially anyway), this is mainly a decision driven off the current maturity of the Ethereum ecosystem. We will evaluate alternative options as they mature.
We will look at developing a mobile app (which will of course have it's own wallet), and also making it web accessible.
Total supply of ROCKT is yet to be determined (and will likely be driven off total raise), we will release the details with an ICO announcement soon
Any other questions, please let us know!
