The Keystone 3 Pro open-source hardware wallet offers unbeatable security with 3 PCI security chips to manage Bitcoin and other crypto assets offline.

Our impressions

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

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.

Our 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.

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.

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.
