How can I sign a message in the new blockchain?It seems I can't find a sign button there,I've only seen the verify one.It's not in the manage options.
By
blockchain I assume you are referring to blockchain.info
To sign a message, go to the "Settings" tab on left, Click on "Addresses", Click on "More Options" in front of your required address, Choose "Sign Message" .
Does the new version allow signing messages? My last info is only the old wallet version does.
