LEARNING 2 of 3 multisig and have question:

Supposing I have only the seed words from 2 of the coldcards

If I have the coldcard multisig export file that I used to create the wallet in sparrow, the .txt file, is that file enough to rebuild the wallet if for whatever reason the third seed was lost or compromised? Or similarly the sparrow wallet export file as .txt since they’re the same.

Do I need to secure generic .json files from all three coldcards as well? or is that overkill?

I just want to make sure that I sufficiently back up everything that needs to be backed up for a multisig setup.

Will zap for guidance. Thank you.

I will have to look at my setup again, but I set my multi-sig up with sparrow. You need the QR code that is the combination of all three public keys. Without that you won't be able to "recover" somewhere else unless you have all 3 keys. I think that was the Sparrow.txt file.

Also nostr:npub1xsmvdul9cyz3822el3ld008mmueyz7yvlfghlzfx2r6g98lzy6jq68hmmk I highly recommend you write down which seed phrase is which. Mine was easy because I used 3 different brands. So I can say cold card is #1 and Jade is #2... But idk if you're an iOS user, I used blue wallet from the app store and set it up as a "watch-only" wallet. Basically you scan that QR code. It'll let you watch all your balances on your phone AND you can retrieve a receive address from wherever you are without needing to be at your sparrow setup. If you're ever in an "oh shit" moment, you can also enter the private keys into blue wallet and drain it to somewhere else quickly.

Just a thought for you.
