My concern hower is how do keychainX intend to make this process transparent for the users to be able to find it interesting and useable. And how can the safety of sensitive informations sent out be assured.
This is also my concern because old device having the wallets will definitely have other sensitive information which if compromised and put into wrong use can cause serious harm to the individual. Hence, there should be some level of assurance that the safety of these sensitive data are guaranteed, but how to make this assurance is the challenge since we are talking about physical device here.
