Does anyone know how to sign Iota address with a BTC address if a purchase was sent from Electrum? A short guide in Italian (or English at least) would help one of our camarades.

I hope this is still valid:

Make sure electrum is running so do sanitycheck: ( this is done in shell terminal or windows command promp!)

Code:

electrum

then see what this command tells you. If not works then go to directory where you downloaded electrum and try

Code:

./electrum help signmessage

and should come back as

Code:

Signs a message with a key
Syntax: signmessage

If it works and you can reach electrum through terminal and get some response back then you can next do this:

Code:

electrum signmessage

Where is

put your address which one you want to prove you have control over.
Where is just copy paste the full message with how many lines you need but make sure to convert it from multiple lines to one LONG line with notepad or something so it is just one huge long line instead of multiple line with space inbetween.

Hope i helped!
