Can we sign our Magna Address with a text that is something else as the KMD address ? We are basically using the KMD address to sign the MGN address, generating a signature string, am i right ? But we can use any other "text" to sign the MGN address, right ?
It's optional. It would be easier and less confusing to use your KMD address for signing the message, however, the message content can technically be anything.
