Coldcard users, can you use the device as a signing device for multiple wallets by using multiple SD cards all with different phrases ?

Multiple addresses of course, but not multiple private keys I don't think. I haven't tried with mine. I just use multiple addresses and label them all for different things. Some are KYC Bitcoin and some are clean.

It does support multisig.

That’s exactly why I was wondering lol, idk why but I don’t want to use the same seed for both stacks. Might just need to get 2 separate devices 🤷🏻‍♂️ . None the less going to play around with it when it arrives

It's impossible to determine that two addresses belong to the same private key unless they interact with one another, for the same reason that it's impossible to determine a private key from a public address.

That’s a great point maybe I’m just being a little extreme and paranoid lmao
