I have a Coldcard single sig seed that has funds on it.
Can I use that same seed to set up a new multisig 2 of 3?
Or do I need 3 brand new seeds?
Discussion
Good question, I'd also like to know definitively.
You can use the generated seed of course, but not sure you can use the coldcard to sign your multisig utxo in this mode. (I haven't seen an option to run in two different modes). The coldcard multisig setup asks that your multisig descriptor be provided so it understands the full multisig setup. I'm assuming this is neccessary, but not 100% sure, thats probably why we both have the same question.
It can be restored and setup again with a different config. Mayby workable.
In Aus we arent supposed to use personal hardware if the hardware wallet is for official retirement savings, needs to be totally seperate.
