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.

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 

Product Description

The Offline Paper Wallet Generator is a DIY project and its firmware is available on GitHub. It is a private key generator but other than that has no other wallet features.

This project aims for a microcontroller-based private key generation. The private key will be generated using rng. Your bitcoin address will then be calculated from your private key. Both will then be displayed on a display, for you to transfer on a piece of paper, which you will keep save. You can now use the address to transfer your bitcoins. Once you need your bitcoins, you simply import your private key in a wallet program and for safety reasons create a new paper wallet with this device. You can then use the bitcoins you need and transfer the rest to your new save bitcoin address.

Additionally, the repository gives instructions on how to flash the firmware to a printed circuit board (PCB).
