Hi Guys,

I need you support one more time.

I just created a MultiSign Wallet 2/4 and I would like to know the best process to Backup and Restore that wallet.

Thanks,

Fabio

Do you control all the cosigning devices or are they owned by other people?

To restore the wallet you need the xpubs (MPKs) of all 4 wallets and at least 2 seeds to spend. Note that the xpub can be derived from the seed so essentially you need 2 seeds + 2 xpubs belonging to the other cosigners.

You can backup wallet files by writing down the seed or making a soft copy backup via file menu > save copy. Soft copy backup will include the other cosigner's MPKs  so it's preferable.
