1  Bitcoin / Electrum / Re: Best practice when testing seed rebuild. on: June 23, 2017, 07:20:51 AM
Hmmm, but can't I rebuild on an off-line computer and then export some parts for a watch-only wallet on an online computer?

Of course you can.  You rebuild from SEED on your offline computer.  Now you can see all the addresses and confirm they are correct.  If you want to rebuild the activity using a watching only wallet that is super easy.  On the "offline computer" with the full SEED wallet you can copy and paste the MASTER PUBLIC KEY for the wallet.  Just paste it on a usb stick and then go to your online computer and create a watching only wallet on Electrum.  Nobody can steal any coins with only a MPK because it doesn't contain the private keys needed to move coins.  With this method you NEVER place any private keys online.  See, easy and safe.

Thank you! I will try that.

I have a wallet with 2FA that holds a lot of BTC, but I have never tried rebuilding it from the 12 word seed. Should I try it just to make sure it works or can I trust that it will work if I ever have the need?

If I should try it what it the best (safest) practice? Boot on some live CD with no internet connection and then export the public master key?
