[LIST] Open Source Hardware Wallets

[dkbit98]

Open source software is made freely and available for possible modification and redistribution by anyone.
Bitcoin is open source and I think that Hardware wallets should also be Open Source so that everyone can check and verify their code.
Not all wallets are open source, and who knows what code they have and if someone can post firmware update with big bug or malicious code.

Hardware wallets with Open Source firmware:

• Trezor One; model T; Safe 3; Safe 5 ^{c r}
• Bitbox* ^r
• Passport** ^{c r}
• Jade
• Satochip
• Keepkey* ^r
• Prokey*
• OneKey Classic*; Mini, Touch
• HyperMate
• Bitlox
• Keystone3
• Portal

Coolwallet Pro, Coldcard, BitKey, Cypherock X1 and Safepal X1 devices are source available, NOT open source.
Hito (pre-sale)?

* based on modified Trezor code
** based on ColdCard code
^c open source hardware certified by OSHWA
^r firmware reproduced by walletscrutiny or bitcoinbinary.

DIY Open Source Hardware wallets (signing devices) (only for advanced users):

• Jade DIY Wallet
• Bowser DIY Wallet ^r
• Trezor DIY Wallet
• PiTrezor DIY Wallet ^r
• Specter DIY Wallet ^r
• SeedSigner DIY Wallet ^sd
• Krux DIY Wallet ^{sd r}

^sd Signing Device without permanent storage.

You can check and verify if someone managed to reproduce firmware for this hardware wallets using two websites walletscrutiny and bitcoinbinary.

Open Source can also have bugs, and code should be verified and checked before installing.
If anyone knows any other open source hardware wallet please post it here so I can update my list and make corrections.

As I did a little research for my list of hardware wallets in the Croatian local section, I discovered another company that uses Open Source for their wallet firmware:

Skywallet - The firmware has been modified from Trezor
GitHub: https://github.com/SkycoinProject/hardware-wallet

Skywallet - The firmware has been modified from Trezor

Thank you for suggestion, but as far as I can see this wallet is not supporting Bitcoin but just their own skycoin, and maybe in future they will add Bitcoin and other coins.
When they add Bitcoin I will consider adding this wallet to the list.
I don't understand why not using Bitcoin from start when they used Trezor firmware.

The Skywallet was made for Skycoin, but a future firmware upgrade will enable you to hold hundreds of coins and tokens on your Skywallet, including Bitcoin, Ethereum, and more.

It seems you may be right. I never noticed that before. 
I'll have to update this info on my list too.

------------------------------------ Satochip Wallet ------------------------------------

Take a look at Satochip hardware wallet.
It's an open source, affordable and community driven project.

Project is fully open source : https://github.com/Toporin

You can even buy a blank Javacard on the Satochip website, compile the code yourself and DIY your own hardware wallet :

@Tibu thank you for posting your suggestion.

I updated the list now and added Satochip with all other Open Source wallets.


If I missed any other Open Source hardware wallet, please tell me.

What about other Coinkite products besides ColdCard: Opendime
https://github.com/opendime/opendime
https://store.coinkite.com/store/opendime

In my opinion, there should be extra storage space considering that Opendime is like a flash disk without an outer casing.

What about other Coinkite products besides ColdCard: Opendime

You are correct about Opendime, it is open source and I will ad it to the list, but I would not recommend anyone keeping a lot of bitcoins on Opendime.
Thank you for suggestion.

Jade wallet added to the list of Open Source hardware wallets.
Jade is made by Blockstream, supporting Bitcoin and all Liquid Network tokens, and Jade does not have secure element, but it has secure boot and encrypted flash.

Official website with more information:
https://blockstream.com/jade/

[dkbit98]

Prokey wallet is added to the list of Open Source hardware wallets.
Prokey is made in Kuala Lumpur, Malaysia and it's code is based on well known Trezor.

Official website with more information:
https://prokey.io/

[dkbit98]

OneKey hardware wallet is added to list of open source hardware wallet, and it appears they are using some modified fork of Trezor wallet with added secure element, battery and bluetooth support.
You can see familiar Trezor pin screen below (maybe they changed it later), they are using Trezor Bridge and OneKey is compatible with all Trezor compatible wallets like Electrum, Wasabi, Trezor web wallet, Mycelium, etc.
OneKey can also be used as 2FA device same like Trezor, and wallet firmware can be updated via Bluetooth.

HyperMate hardware wallets manufacturer is claiming they are Open Source and you can check that on their Github page but I can't confirm that because I didn't test their wallets myself and it is lacking documentation.
They have two interesting devices offering hardware-level MultiSig support and they claim they are resistant against attacks on program execution, and physical attacks on chips (heated, frozen, filtered...) so it would be good to see someone testing out this claims.
Problem I have with this hardware wallet is that I must use their HyperPay app and can't connect device with other wallets like Electrum, and I can't choose to create my own PIN because it is random generated.

New Hardware Wallet KeyPal added to the list of Open Source wallets according to their statements, but we are still waiting for github code confirmation.
This wallet is one more device coming from China so I would be extra careful trusting them before doing some testing and examination by security experts.
It is made from zinc metal alloy and it has dual chip with secure element and military-level protection, and it is working only in combination TokenPocket wallet by same manufacturers.
They are claiming to have sensory, visual, operational and security features, but nothing can be confirmed because they are still in presale period until September 10.

Hello,

You can also DIY your own Satochip hardware wallet.
We do sell blank javacard that are compatible with our Satochip Applet.

It's quite easy to make your own hardware wallet :
- Grab a card here : https://satochip.io/product/satochip-diy-and-developer-card/
- Load the code here : https://github.com/Toporin/SatochipApplet/releases

Et voilà

Interesting, I didn't know that and I think that €25 it is a reasonable price, but I think that you would need to buy a card reader if you don't have one already, and that is plus €15.
Is there any page with instructions for dummies for making Satochip DIY wallet and loading code on card?

I think what you are looking for can be found on this page. Scroll down to the bottom where they talk about creating your own Satochip hardware wallet. They posted links to the required chips, the files that you need to upload on the chip card, and how to download and configure the various Satochip clients.

Latest updates and changes to the list of open source hardware wallets:

- Coldcard hardware wallet removed because code is not Open Source anymore, but MIT+CC license and it can't be reproduced anymore.
- Added separate list of DIY Open Source Hardware wallets for advanced users.
- Opolo hardware wallet added, but code is still not released and can't be confirmed on github.

dkbit98, thank you for putting this list together. I understand now why open source is imperative for hardware wallets.
In the meantime, I'd like to read more reviews of some of the most popular models from this list, not just the simple listings of technical specs. You might have some resources on the subject in your bookmarks archive. Feel free to share any.

I am not going to provide any reviews here because I didn't personally test all of those hardware wallets, and all other reviews are either paid bias or shilling of their own products.
Do your own research and listen opinions and feedback from several people both positive and negative.
My personal choice would probably be Swiss made Bitbox hardware wallet, it is open source, has secure element and it survived years of testing.

Cobo Vault is shutting down next week.

https://support.cobo.com/hc/en-us/articles/4407973083287-Cobo-Vault-Offline-Notice

Nice to give your users an entire 8 days before shutting down your back end.
Cobo / keystone should still work but no more updates.
But, I would still not use it anymore, you never know what could be lurking somewhere in bad code.
