On COLDCARD you can just select 32byte hex in the BIP85 menu.
Use that to sing into nostr
Yes, but with this we will export in with NIP spec.
Nostr private key derivation
Cool
That will be such a 🔥 - that will be such a great contribution NVK.
BIP85 isnoerfwcr use case for nostr because bip85 enables one to create several keys for several Bitcoin wallets from a single, primary seed. i.e., you just have 1 seed to secure and then all of your Bitcoin wallets are safe. Perfect for people who like trying several wallets. But in this case nostr protocol. The nice thing about this method is that now the only information I need to securely backup is one master seed phrase, the BIP39 passphrase, and the index numbers for each derived key. Then I can take any of the derived keys and import them to a wide range of available wallets.(nostr accounts)
