Are you thinking of something to compete with Nano Ledger and Trezor?

I've always wondered whether some sort of hard wallet within a banks security vault would be of interest. I cant imagine its comfortable potentially having millions of dollars worth of crypto on stick in your house. Maybe it would be nicer, if you could store a ledger in some sort of security vault that you can access remotely.

It would have to be cold storage unless you were using it though, otherwise whats the point?
