This project is not meant for non-technical end users.

As part of our Methodology, we ask:

Is the product meant to be ready for use "out of the box"?

If the answer is "no", we mark it as "Do-It-Yourself Project".

Many hardware wallet projects aim to be as transparent as possible by using only off-the-shelf hardware with an open design and open code. If the product reviewed is not available in an assembled form - if the user has to source his own hardware to then maybe solder and compile software to install on the device it falls into this category.

Help spread awareness for build reproducibility

Please help us spread the word discussing build reproducibility with BitcoinComfy BitcoinMRE  via their Twitter!

Do your own research!

Try out searching for "lost bitcoins", "stole my money" or "scammers" together with the wallet's name, even if you think the wallet is generally trustworthy. For all the bigger wallets you will find accusations. Make sure you understand why they were made and if you are comfortable with the provider's reaction.

If you find something we should include, you can create an issue or edit this analysis yourself and create a merge request for your changes.
