Iโm pretty happy with my Coldcard and Trezor. Starting to wonder what a nostr hardware device would look like. Likely a self-generated master key that never leaves the device with a bunch of derived keypairs that can be provably mapped back to the master public key.

What features do you use the most?
And want?
Custom apps? ๐
The new Passport Prime is designed for custom apps if I remember correctly. Maybe an opportunity there ๐คท๐ปโโ๏ธ
Iโm still getting a handle on what my requirements would be. I want to have root key and a bunch of (disposable) controller keys. The device could sign an inception event and a key rotation event indicating the current controller key. Thatโs about it.
