I remember that on Electrum, it used to have a
Preview button inside the
Send tab. By clicking the
Preview button I could export the unsigned transaction, and then sign it.
I cannot find this button anymore, I can only see
Pay button, and when I clicked it I got a "Not Enough Funds" error. This is because I am doing this in my offline desktop computer (offline wallet).
Is it still possible to create a signed transaction offline using electrum?
