I created a multi sig with sparrow and three cold card, tested it every way I could, including restoring from seeds. Everything cool. I did have one glitch where one coldcard in the multi sig said invalid transaction when signing when psbt was created with sparrow. When psbt was created with blue wallet the same colcard device would sign it. Loading the multi sig config again on that device solved that. Reported this to coinkite support got a we don’t care response, probably Sparrow.

When you restored, and you generated a new multisig config file, does it matter which order the xpubs were in?
Or did you reuse the original config file?
I haven’t experimented with the order of the keys in the keystore.
When restoring from seed phrases i did not use the original keystore file. I created an entirely new setup based on the same seed phrases, probably even in a different order and confirmed i could see the funds and transact them.
Thank you very much for responding 🫂🙏
But i practiced a lot, all kinds of scenarios. But in the end its the seed phrases that make you hardware wallet and vendor independent. That’s a comforting thought.
