- Jade Core available at $99
Cons
- No dedicated physical secure element — the vendor uses a virtual one
- Bitcoin and Liquid only
- Jade Plus at $169.99 costs more than devices with certified chips
A different approach to the secure element
Every other device here relies on a dedicated security chip. Blockstream instead describes a virtual secure element using blind oracle encryption, and states that this model simulates the protection of a secure element and is therefore not vulnerable to physical attacks.
We score the criterion on what is documented, and a virtual element is a materially different guarantee to a chip certified to a published assurance level. That is why Jade scores mid-table here despite topping the open-source and air-gap criteria. Whether the trade is worth it depends on whether your threat model includes someone physically holding your device.
Open source, verifiable
Blockstream states Jade is fully open source and links a repository for verification. Air-gapping extends to firmware upgrades, not just transactions, which is rarer than it sounds.
Bitcoin and Liquid
The comparison table describes the device as Bitcoin-only; the page confirms Bitcoin and Liquid support.
