in interview with Crypto Rich, Boris was talk about partnership with real bank who will issue card. There is record on YT 
I do remember about another partnership which was not named. As for the bank, may be there was such an intension and then it was changed because it is more secure to have own bank.
Could you please clarify which security arguments drove such decision? And also which banks (jurisdiction, tier) were considered / rejected?
and... give us private key for bank's cold wallet
