Hey what’s your setup recommendation for a jade?

Trying to decide between setting it up as a signing device (keys do not persist) and setting it up airgapped with QRs (using Blockstream’s virtual secure element).

Also, should BIP39 be common practice?

Yes on BIP39 unless you really want to geek out on building your own entropy. You could end up making a mistake somewhere and that could be a disaster. I’ve never used it as just a signing device, but I don’t have any concerns about its physical security.

So should I use it with the green wallet app over Bluetooth? Or do you think airgapped with QRs is better?

Tradeoff is I would need to scan multiple QRs every time to make a transaction. What do you think of storing the seed as a QR?

Bluetooth, yes. I wouldn’t want to store the seed phrase QR somewhere that has to be frequently accessed.

Wow I did not expect that recommendation.

Will definitely take it into account. If you had a jade and a Coldcard, how would you take advantage of both?

Some argue that a passphrase is just a 2 of 2 with a single point of failure.

What are your thoughts?
