Hello all,

It's nice to know that Electrum 2.0 beta is out.

I have a couple of doubts with regards to the new version of Electrum.

Question 1: I remember Electrum 1.9.8 had a 12 word seed, but Electrum 2.0 has a 13 word seed on a standard wallet. I opened up my Electrum 2.0 beta and I've seen the seed showing up as 12 word seed, but when I create a new Electrum 2.0 standard wallet it gives me a 13 word seed back for the wallet. May I know if Electrum 2.0 will convert my old 12 word seed or HD wallet to the new 13 word seed or new standard?

Quesiton 2: Whats the difference in wallet architecture from 1.9.8 and 2.0 beta? I heard 2.0 beta has BIP 32, didn't 1.9.8 have BIP 32 or HD wallet?

Question 3: Will there be the ability to easy convert old wallet from 1.9.8 to new wallet of 2.0, or also to Multi sig wallet or 2FA wallet?

Kindly guide me on this.

Thank you

Q1: a wallet seed cannot be "converted", this does not make sense.
Old seeds are supported, that's why you can still use or restore your old wallet.

Q2: previous versions did not use BIP32 derivations.

Q3: again, you do not "convert" a wallet.
All you can do is create a new one, and send your coins to it.

if you couldn't use your old seed, you can always use import in order to import your private keys. but as previous comment said creating a new wallet and sending coins is better

Thanks a lot ThomasV for clarifying my doubts!

Since Electrum now supports BIP32, can it's seed be restored on Mycelium wallet for android as it also supports BIP 32?

No, that will not work, unless they decide to use the same seed format.

Thank you for the response! and helping around.

I found that on starting the new Electrum 2.0 beta I get a C++ Runtime error, although the wallet app later does work. Is this error any serious? https://i.imgur.com/DqkmIrX.png

Also once I ran Electrum 2.0 Beta, I wasn't able to run the installed version of 1.9.8 again. Do I have to reinstall 1.9.8 to fix this?

version 2.0 will convert your wallet file to a new format, which cannot be read by 1.9.8. anymore.

This is why you should make a backup of the wallet file, and check the integrity of your seed backup before updating, or more important when using BETA versions of any wallet software.

I have the backup of my seed written down offline and I believe that's enough. I never said I had lost access to my wallet, so I know what I was doing there by using the BETA version. I had also exported backups of my labels. And also as Thomas said that Electrum 2.0 converts the wallet into a new format and thus 1.9.8 wont read it. The converted wallet works well and good and I can access my wallet fine on 2.0, it's just that I had the doubt why it wouldn't run on 1.9.8 before, but now that's cleared.

Does it work if the user simply imports his private keys into the new wallet?
