Crypto hardware wallet comparison Keystone 3 Pro vs Blockstream Jade

Our impressions

Keystone 3 Pro

Blockstream Jade

Pros
  • Supports 3 concurrent seed phrases
  • Convenient user experience with the huge touchscreen
  • Completely autonomous device with long lasting battery lifetime (should be at least 100+ hours in sleep mode when using the device a couple times per day, 18+ months when turned off)
  • Easy process for online Device Verification
  • Camera for fully air-gapped transactions + QR code support in hardware
  • Firmware with radio and without radio support (Bluetooth + Wifi)
  • Wifi capable (already on board but currently disabled)
  • 100% open source: firmware, hardware + casing
Cons
  • The airgapped QR code paradigm requires a camera on the paired device for certain interactions
  • We love their dedication to open source “EVERY SINGLE LINE” of code they write, including their hardware designs. As long as they do not deliver on their promise, it sadly still is a closed source product.
  • Only supports Bitcoin and Liquid assets
Verdict

The Keystone 3 Pro is a device that we can see in a “broad adoption of everyday Crypto financial transactions” scenario. It is a fully air-gapped, autonomous device that has great battery life with an easy to use interface on a convenient 4-inch touchscreen. We would add it to our everyday carry in an instant, in a world where QR code based Crypto payments are available at every shop and venue.

Please note that we do not yet own a Blockstream Jade. Our verdict currently is based on available online resources only. We love the 100% open source approach and can’t wait to get our hands on one.

If your use-case is Bitcoin ecosystem only, this seems like a very good option to secure your valuable Bitcoin assets.

Disclaimer: Our impressions are based on a compilation of factors tailored to the average user’s perspective. It is also important to note that whether a feature is a “pro” or “con” can depend on your situation and preferences. What may be an advantage in one scenario could be a challenge in another, and vice versa. Therefore, while reviewing these points, it’s essential to consider your unique requirements and circumstances when making decisions. This list aims to provide an idea of what to anticipate, but it is not the ultimate guide to determining whether something will work for you or not.

Supports only Bitcoin

  • Bitcoin and Liquid sidechain are supported
Open source
  • Planned

The Keystone team is working on also open sourcing “EVERY SINGLE LINE of code we’ve written”, including their hardware design, with an announced release date in November 2023. The announcement is worded in a way that it leaves some room of what we really can expect to be released and if they can meet their own release date.

As the focus of the Keystone 3 series is on 3rd party app compatibility the previous companion software will be faded out in the future.
