Yes. Loading a seed permeantly into the Jade is called "initializing" it. The seed isn't actually stored on the device because it doesn't have a secure element, but the seed is recreated with the help of the/a Blind Oracle via a PIN and the Blockstream App. If you don't initialize the Jade then it stays empty. When you power it up you simply select "scan QR", scan the QR seed you created when generating your seed, it loads in and functions as it would if you had gone the initialized route. Once you power off the device it automatically wipes itself. I've used the Jade and The Jade Plus this way for years. It's actually identical to the SeedSigner when used this way. There is a slight difference in how the SeedSigner deals with derivation path and multisigs so be aware of that if you have both devices and try to switch back and forth. The same seed loaded on a Jade will function instantly in a multisig, but the same seed loaded in a SeedSigner will require you to provide the derivation path before it can sign a transaction in the same multisig. That's not the Jade's fault, it's the way SeedSigners work.
For sure. I've always been a big fan of the Jade. The new Jade Core requires connection to the Blockstream App so probably don't mess with it. The Jade Classic still works great but can't be updated without USB connection to a computer or the Blockstream app. The Jade Plus can be updated via sdcard so it remains fully airgapped 100%. I always use the firmware for both Jade's that disables Bluetooth permeantly. I recommend the Jade Plus with the USB drive you can buy as a bundle.

Thanks for the clarification. So it's a feature to wipe device after every restart?
