I seem to be unable to sign a message with Electrum (Windows, Version 2.7.12). I go to the “Addresses” tab, right click on the address, choose “Sign/Verify Message” and enter the message, only to get “(False, 0)”. Am I doing something wrong or is this just a bug? I’m using an imported private key if that makes a difference.
Error ScreenshotThe version of Electrum you are using is outdated. I'd recommend you try downloading the latest version which should fix this bug as shown:
# Release 2.7.13
* fix message signing with imported keys
