Re: [ANN] Armory Multi-Sig with Simulfunding [BOUNTY 0.03 per bug]

Apologies if this has been answered elsewhere but I have a question about lockboxes. I understand how to set them up but I'm curious about backup strategies for them.

Your answer is here. Basically, all you truly need are for the private keys to be backed up (e.g., paper backups), although you can back up the lockbox definition and save yourself some setup time. As long as there are enough signing parties, you're good. If there's corruption, the keys will have to be restored.

Thanks for the prompt response. I actually just happened upon the answer (and have the same link in my clipboard to paste here actually). What about a case where the lockbox definition is lost on the organizing machine and neither / none of the others imported the definition? Is there a way, without the definition, to restore the lockbox? Let's assume the cases of you know the public keys / addresses that were originally used to create the lockbox, you know one key that was used to create the lockbox, and the rare case that you can't remember which key was used to create the lockbox (but maybe you know which wallet was used).

I hope my question here isn't too ignorant.

Ultimately, the list of the public keys is all that matters. If know what public keys were used, you can recreate the lockbox. If you just know what wallets were used, you'll eventually figure it out, though it might take a script to do. Nonetheless you'll get your coins back. But this should be mostly irrelevant we assume that not all your devices are losing it or getting destroyed, or you might have bigger problems. As long as one of them still has the definition, you just export-import.

Or backup the multisigs.txt file to save yourself some time. We just haven't made an option for it because we didn't feel it was necessary (though we'll have some automatic backup features with the new wallets, for saving address/tx labels and lockbox definitions)
