Our impressions

BitBox02

KeepKey

Pros
not reviewed yet
  • Has a great community and (d)app ecosystem
Cons
not reviewed yet
  • Outdated microUSB port
  • Needs constant USB connection
Verdict
not reviewed yet

The product has a nice build quality and finish, a solid (d)app ecosystem, and a great community. The product launched in 2015 and it shows its age, compared to newer hardware wallet products. Most notably it has no secure element, a microUSB port, and limits itself to a single button for on-device input.

That being said, we would still prefer it over any software wallet, though.

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.

Supported coins

Supports multiple coins

In app support for BTC, LTC, ETH and selected tokens.
ADA with AdaLite and 1500+ ERC20 tokens supported with MyEtherWallet.

For Bitcoin-only support see BitBox02 Bitcoin-only edition

It is not possible to convert a BitBox02 Multi edition into a BitBox02 Bitcoin-only edition or vice-versa. The BitBox02 bootloader prevents firmware downgrades and installing firmware for a different edition of the BitBox02 (Multi or Bitcoin-only) as otherwise that would be a security attack vector.
