Title: How to proceed with Paper Wallets?
Post by: nexus6 on February 06, 2014, 08:14:48 PM
Hi guys,

I'm new using Electrum since 2 days ago and I'm loving it so far but I have a doubt and I wanted to ask the experts around here before screw it up.

My setup is:

An off line computer with a "complete" Electrum installation and a laptop and a cell phone, both with seedless installations.

The thing is that I have a couple of old paperwallets with no BIP38 encryption and I wanted to send the funds to a new BIP38 paperwallets that I've previously generated and printed.

So, what is the best way to proceed if I import both paper wallets to the offline installation?... AFAIK the offline Electrum won't have the updated funds and I really don't want to set the network up.  ???

Thanks  ::)

Import the private keys into the offline wallets

Create a seedless wallet for use on your online systems. You do it using the command line:

electrum -w /path/to/wallet deseed

If it's the default wallet you can skip the "-w /path/to/wallet"

It will create a .seedless file that you can use on your online systems.

Then proceed as you would with any offline wallet transaction i.e. to an unsigned transaction on the online system, sign it using the offline system and broadcast using the online system.

Great, it worked smoothly..

Now remains one last thing, how can I update de balances in the offline machine?

Thanks


EDIT: Nevermind, I've just found the answer. It's only possible putting the machine online.  :-\
