Custom URLs: Wallet Comparison

Our impressions

Trezor Model T

Keystone 3 Pro

Pros

Very high usability through the touch-screen
Future-proof USB-C port
Uses the BIP-39 standard, which allows wallet recovery even without hardware
Open source firmware that can be audited by the community
Can be used as a secure key, providing additional value outside crypto use-cases
Also includes unique features for highly advanced users, like Shamir backup

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

Requires constant USB connection to operate
Key extraction vulnerability (if an attacker with the right tools and knowledge has physical access to the hardware wallet)

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.

Verdict

In our opinion currently one of the best hardware wallets on the market. We especially love the usability that comes with the touch screen. Make sure to use a passphrase if you are worried about key extraction attacks. Read more about the vulnerability

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.

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.

Companion software

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.
