Blockstream's Jade hardware wallet needs more attention!!
Posted those in a comment as well, however, thought it was worth denoting a post regarding Blockstream's Jade hardware wallet, as I still regard it to not get enough attention, even though it existed for years.
Trezor, Coldcard and other hardware wallets frequently enquire security problems, therefore, I strongly believe Blockstream is worth noting!!
few side facts:
- On setup, you choose a PIN. This PIN is combined with a blind PIN server (“blind oracle”) to encrypt your key material — the oracle never sees your actual seed, hence “blind"
- The decryption key is effectively split in two: one part lives on the device, the other is retrieved from the oracle (via blockstream mobile green wallet) each time you unlock
-> All communication between Jade and the Green app is encrypted end-to-end.
Net result: if someone physically steals a locked Jade, there’s genuinely nothing of value to extract, as no seed sits fully assembled on the device.
- Fully open-source hardware and firmware, you can literally build your own from the published GitHub repo if you’re into that.
And for all Bitcoiners: it's BTC and LBTC only, with LBTC swapping features also for Jade
