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.

But we also ask:

Is the product still supported by the still existing provider?

If the answer is "no", we mark it as "Not functioning anymore".

Discontinued products or worse, products of providers that are not active anymore, are problematic, especially if they were not formerly reproducible and well audited to be self-custodial following open standards. If the provider hasn’t answered inquiries for a year but their server is still running or similar circumstances might get this verdict, too.

Help spread awareness for build reproducibility

Please help us spread the word discussing build reproducibility with Stepan Snigirev Simple Bitcoin DIY Hardware Wallet  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.

The Analysis 

Background

From the Simple Hardware Wallet page:

A minimalistic hardware wallet working with electrum transactions.

This sketch is a simple demo that shows how to use arduino-bitcoin library to build your own hardware wallet.

It should be used only for educational or testing purposes as default Arduino boards are not secure, their firmware can be updated from the computer and this process doesn’t require any user interaction.

Project Requirements

  • Adafruit M0 Adalogger board with SD card
  • Adafruit OLED screen
  • Headers
  • Soldering station to solder the headers and pins
  • USB cable
  • SD card (16 GB or less work fine, not sure about larger)
