vishal on Nostr: I wanna level up my BTC security by going multi-sig and giving a bunch of keys ...
I wanna level up my BTC security by going multi-sig and giving a bunch of keys (probably in the form of steel seedQRs) to my family members. My plan for getting comfortable with multisig is to use a single SeedSigner and have 3 private keys put onto a paper seedQR, and have xpubs (I’m aware that you need to safeguard all m xpubs) in some other form (also QR?). I’m going to test 2 or 3 multisig on testnet via Sparrow. While this will teach me the mechanisms of sending and receiving with multisig it might not be what I necessarily go with. To elaborate: I understand that not trusting a single manufacturer is recommended for your setup.
1. For my real life setup should I generate private keys + xpubs with other devices like Coldcard, Fountain Passport, etc?
2. Should I not have n (n of m multisig) keys generated from devices by the same manufacturer?
3. How does my learning approach sound?
