Importing a multi-signature account into electrum

[jza]

I generate a multi-signature account but I cant seem to get it to work with electrum. I have my account and the private/public keys on a text file, and I want to insert it into my wallet. The IRC room told me Electrum wouldnt let me do much until I generate a wallet first. But once running I couldnt tell how to import my account.

Please let me know what are the steps to get a multi-sig account (or any other account) to work with electrum.

Regards.

Use file > new/restore to create a new wallet. Choose to restore and choose multisig as the wallet type. Then just paste in the extended private key of your wallet and the extended public keys of the other participants.

Electrum crash after this, it gives me the following traceback on the console:

Also when you say extended masterpassword do you mean the Private key like the 52 character key or the public key, the 66 character key.

Is it possible for all participants to be hardware wallets ? In which case electrum won't have any xpriv.

I didn't say extended master password. I said your extended private key and the extended public keys of the other participants in this multisig wallet. You can see examples of extended keys here. xprv... = extended private key and xpub... = extended public key.

Thanks @nerioseole

What I would like to try is this, which is useless in Armory as it doesn't import compressed keys.  Will see if electrum can be a failsafe for Coinkite + Ledger multisig.
