The short answerJade proves a serious hardware wallet need not cost $150: fully open firmware, optional air-gapped QR mode and Bitcoin plus Liquid support for around $65. It has no secure element, relying instead on a design that splits the secret between the device and a Blockstream server, which is defensible but not equivalent.

What we liked, and what fell short
Liked- Fully open firmware from a well-regarded company
- Air-gapped QR mode available alongside USB
- Very low price for a genuine hardware wallet
Fell short- No secure element; physical security relies on the virtual-secure-element design
- Bitcoin and Liquid only
Why the marks landed where they did
Jade is Blockstream's answer to the question of why a signing device should cost as much as a phone. The firmware is open, the company is Bitcoin-native with a long engineering record, and the price is a third of the premium devices.
The virtual secure element
Rather than a certified secure chip, Jade encrypts the key with a secret split between the device and Blockstream's server, so extracting the flash memory alone yields nothing usable. It is a real design rather than a marketing claim, and it introduces a dependency: full functionality assumes the oracle service exists. Blockstream provides a self-hosted option and the seed remains standard BIP39, so recovery never requires the company — but the physical security model is weaker than a certified element.
Air-gapped mode
Jade supports QR-based signing as well as USB, so users who want isolation can have it without buying a more expensive device. Paired with Sparrow or Green, the workflow is straightforward.
Coverage
Bitcoin and Liquid only. That focus keeps the firmware small and auditable, and it rules the device out for anyone holding anything else.
Who should use it
Bitcoin holders wanting open firmware on a budget, users building multisig quorums who want vendor diversity cheaply, and anyone buying a first device to learn on before committing to something more expensive.
FAQ
Does Jade have a secure element?+
No. It uses a virtual secure element that splits the key-encrypting secret between the device and a server, so flash extraction alone is insufficient. That is weaker than a certified chip.
Do I depend on Blockstream's servers?+
For the oracle component of the security model, yes, though self-hosting is supported and the BIP39 seed can always be recovered on any compatible wallet without the company.
Which assets does Jade support?+
Bitcoin and Liquid only, which keeps the firmware small and auditable.
Is Jade good for multisig?+
Yes, and its low price makes it practical to use different vendors for different keys in a quorum, which is good practice.
