Blockstream Jade Jade (classic)
A plan byBlockstream Jade
Blockstream Jade is a low-cost, fully open-source hardware wallet (firmware and hardware) developed by Blockstream. It supports Bitcoin and Liquid Network assets, and offers air-gapped QR-code signing via its built-in camera, as well as USB-C and Bluetooth. Instead of a closed-source physical secure element it uses a 'Virtual Secure Element' (keys are encrypted and protected by a Blockstream blind oracle), a design choice that keeps the device fully open-source. The classic model costs about €73 ($79); the Jade Plus about €155 ($169). Companion app: Blockstream App, but it is also compatible with Sparrow, Electrum, Specter, BlueWallet and Nunchuk.

Verdict
Score 4.3/5, very strong profile. In its favour: fully open-source (firmware and hardware); cheap (≈€73); Bitcoin + Liquid support; air-gapped QR signing; broad compatibility with third-party wallets (Sparrow, Electrum, Specter). The trade-off to weigh: no certified physical secure element (uses a software 'Virtual Secure Element' relying on a Blockstream blind oracle); focused on Bitcoin/Liquid, not a general multichain device; small screen on the classic model.
On the Sovereignty lens the score is 5.0/5 (outstanding): the strength is privacy & anonymity (5.0/5), while censorship resistance (4.8/5) is the weak link.
