[LIST] Open Source Hardware Wallets

[dkbit98]

Cobo Vault is shutting down next week.

Nice to give your users an entire 8 days before shutting down your back end.

I wrote about this news few months ago (June) in their topic and everyone was aware that something like this was coming.

Cobo / keystone should still work but no more updates.

I would not use Cobo anymore that needs to be connected with their custodial wallet, but you can buy new Keystone device with 50% discount if own old Cobo device (Keystone essential with discount would be around $60, and Keystone Pro around $85).
Keystone is working with most software wallets like Electrum, and you can use spare parts and batteries from old Cobo device.

But, I would still not use it anymore, you never know what could be lurking somewhere in bad code.

Their wallet is open source, so there is nothing hidden and anyone can check the code, plus their developer LixinLiu is very active and trying to help everyone.
I am not trying to justify anyone, Cobo made a bad decision

Cobo Vault is shutting down next week.

Nice to give your users an entire 8 days before shutting down your back end.

I wrote about this news few months ago (June) in their topic and everyone was aware that something like this was coming.

Not everyone, someone not on the forum asked me about a tweet they saw about it, which is why I posed here.

I did a quick google search for wallet not vault (so that's on me):

Code:

cobo wallet site:bitcointalk.org

The 1st 3 or 4 results were all to the altcoin sections. So I thought (incorrectly) that there was no dedicated post in the HW wallets section.
Their topic has fallen to the 2nd page so even a quick look did not show it on the hardware wallets page.

At that point I figured a post on this thread was worth it.

Their wallet is open source, so there is nothing hidden and anyone can check the code, plus their developer LixinLiu is very active and trying to help everyone.

Did not mean bad as in going to steal your BTC, but bad as in "whoops that little bit of code does not work the way it was supposed to" and you now have a device that is not doing what you want. The same way any piece of unsupported hardware can have issues that will not be resolved.

As for LixinLiu and all the rest, if you look at the tweets from cobo and on the article I linked it does not mention him. So, look at it as someone who bought this product and got the shutting down info and has seen no other communication from the company.

I got a call last night, did a quick (wrong) search and followed the few links that cobo provided and sow nothing.

Just what happened.

My Opinion: If keystone / LixinLiu want to keep going they really should be posting here about it in a new topic.

LixinLiu was lead developer who worked for Cobo before, but when they decided to ditch their hardware wallet, he separated with his team, purchased license from Cobo and created new brand and company called Keystone.
They made some improvement changes in QR codes, changed place for entering SD card, code is the same like in Cobo but it will change in future.
It is a a good idea suggesting him to create new topic with support here in bitcointalk forum.

Wait, so you actually own a Cobo hardware wallet?
I remember they offered some devices for free or with discount few years ago in forum.

No, a consultant that I deal with a lot has one. But, since I am the go-to guy for crypto stuff, he saw the tweet that they were shutting down and gave me a call.
Which does bring up the point, that they had his email and did not even contact him. Not a great way to do business.

Hey I am Lixin. One of our users shared me the link of this post in our Telegram group which guided me here.

Thanks for your explanation for what happened.

I am new here. Should I apply for opening a new topic (or maybe an AMA?) to answer people's questions about the rebrand?
(I don't want to break any rules here.)

Welcome to the forum.

As a courtesy to this thread and the thread users, you should probably start a new topic - especially since this topic is about a variety of open source wallets rather than just your own wallet, and presumably you are going to want to both promote your own product and to make comparison and contrasts that revolve somewhat around your own product rather than openly exploring various open source wallets, which seems to have been the intent of this here thread.

And for sure, you could put a link to your new thread here.  Of course some people are going to want to know that you are not a fake (which I see you made a subsequent post to attempt to address that), so you might need to provide some information to verify your representative status.  

For sure, if you start a thread, you would likely be posting some links to overall introduction topics, and of course if specific questions are being raised in this thread they could either be answered here or in your thread (in which you would probably redirect people to the specific answers or the status of certain matters that might not have answers at the moment).

In your new thread, you may also want to provide some links to some podcasts because I believe I have heard interviews from you or someone else from your company/project at more than one time on some podcasts.  I cannot remember which ones, but you probably know about those more specifically - or if you believe any of the interview(s) might be helpful.

Hi Lixin and welcome!
This is general topic for all open source wallets.
My suggestion that you should first make a post explaining what happened with Cobo wallet, your team and new brand you started in old Cobo topic:
https://bitcointalk.org/index.php?topic=5244214.0
Than you should create new ANN topic for Keystone hardware wallet, post some information, links and images (maybe you will need copper membership or more posts for doing that)
Hardware wallets section is here: https://bitcointalk.org/index.php?board=261.0

I think you proved a connection with your twitter account making your previous post, so only thing left is to read bitcointalk forum rules and you are good to go:
https://bitcointalk.org/index.php?topic=703657.0

My suggestion that you should first make a post explaining what happened with Cobo wallet, your team and new brand

I'm really very confused right now. I was recently looking up the Cobo Vault again and saw they switched brand to Keystone a while ago.
Now, Cobo says it stops supporting the Vault - but why don't all Cobo Vaults just continue working and continue being supported under Keystone?
Is there any difference between Keystone Vault and Cobo Vault at all?
I hope these questions will be answered in a new topic by Lixin.

Edit: I think everything is answered in: Hey bitcoiners if you are interested in the rebrand from Cobo to Keystone...

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.

COLDCARD code can definitely be reproducible see here https://bitcoinbinary.org/

COLDCARD code can definitely be reproducible see here https://bitcoinbinary.org/

Maybe it is reproducible now, but I wrote that post in August and I think that you released your website one month later, after you donated yourself for creating it.
We talked more about that subject in different topic, and I have to say that you made terribly bad selfish move when you changed and removed Open Source license from Coldcard.
Is your code 100% made by you or you used code parts from other open source hardware wallets like Trezor?

1. That's incorrect, I seeded the donations and the bounty was paid to the first submission Achow101. That website is open to anyone to submit, I wish more people cared and donated to pay bounties.
2. Code has always been viewable and buildable. Repro builds started a few versions ago, not since the begining.
3. Also incorrect, COLDCARD only shared one crypto library with Trezor which we were contributors. That library was since replaced with Core's Libsecp256k1, far superior.

Before so much negativity, maybe do a bit of research

First archived version of your website shows a different story, and first ''donation'' was from Coinkite (Coinkite = Coldcard = nkv), only later you added one for Achow, but I guess you can time travel:

Code has always been viewable and buildable. Repro builds started a few versions ago, not since the begining.

So Coldcard was never open source and it never changed a license?
I think LICENSE is more important part of the question that I was asking, like topic subject is, not if wallet really is reproducible or not.

I was asking a question, so I don't know how I could be wrong about that.
Maybe you should have a bit less pride and arrogance, but that is just my opinion :/

The commit history is public on github, first CK donated, then achow was paid the bounty. I don't understand what's your problem here. The site is new and was continually updated.

Some interesting turn of events happening in China with OneKey, biggest hardware wallet manufacturer in China.
After recent ban from government they had to make some drastic changes for their customers who live in mainland China, canceling anything related with dex, staking, defi and lending.
This makes me think if they could potentially stop future maintaining of their code and nodes that operate transactions for coins.
OneKey claims they are based in Singapore but I think we all know the truth 

To users in China:

On September 24, 2021, ten Chinese ministries and commissions jointly issued the "Notice on Further Preventing and Disposing of the Risks of Virtual Currency Trading Hype" (hereinafter referred to as the "Notice")
From now on, OneKey will terminate the relevant part of the functional services for users in mainland China, terminate the third-party financial applications that may involve transaction-related and that do not comply with the "Notice" or other regulatory documents or laws and regulations, and retain the basic service functions of the wallet.

Third-party applications include but are not limited to:

-DEX: Decentralized currency exchange
-Staking: pledge mining, liquidity mining
-DeFi applications such as lending and derivatives

OneKey will continue to devote itself to users' trusted digital world products, and continue to move forward on the road of convenience and safety.

New hardware wallet OneKey Mini added to the list of open source wallet, but their github page is a mess full of deprecated and old firmware so watch out if you are confirming their source code manually.
Device itself looks interesting, it has unknown secure element and very affordable price with free shipping from China.
From information I have OneKey is currently most popular hardware wallet manufacturer in China.

Missed opportunity to give the thing a click wheel
That makes me wonder: fuse iPod Classic modding + DIY hardware wallets => hardware wallet in iPod shell? Would be pretty sick, and also a way to hide keys 'in plain sight'.
Although, it would be a much more involved project than regular iPod modding, it would be reusing shell & I/O with all-new components. Not sure if even possible. I'm just brainstorming

OneKey mini looks like iPod device but it has much smaller dimensions, and I don't think it's possible to create functional DIY wallet with iPod.
There was some iPod Linux project few years ago but I am not following the progress, and it's probably cheaper to just buy open source Onekey.

maybe someday I can buy one of my dream hardwer wallets, I just read about Trezor from a physical point of view, its advantages and specifications,
oh yes, the friends above are busy discussing the mini one key whose shape is attractive and simple so it is practical to carry it everywhere. I hope other countries don't join in and ban it from using it, and the Chinese country hopes that there is a solution until the ban is lifted. this presence makes it easy, I have also read the prices of other hardware wallets here

https://bitcointalk.org/index.php?topic=5282364.0

I'm starting to understand and it's interesting, especially when there are physical/materials that are easy to carry, thanks OP

No matter how big or small, if your hardware wallet holds the majority of your funds, or one big stash of it, carrying it with you in your pocket everywhere you go isn't recommended. Hardware wallets have been and still are/could be vulnerable to various types of physical attacks. It doesn't matter if the wallet is protected by a PIN, it's a line of defense can be penetrated with enough time or willpower. Keep your HW hidden like you would with other things valuable to you. Carry only the things you need on you. It's better to lose $1k than $100k because you were flashing your Trezor in public.

[Pmalek]

have you ever done or such a heartbreaking incident bro?

I can't remember one from the top of my head. Personally, I have never found myself in such a situation. You can apply the same logic to fiat money. If you need to run down to the shop for a package of milk and a dozen of eggs, you aren't going to put $10.000 in your trousers, take it all out, and start looking for a $10 bill in front of the cashier and other customers. You are putting yourself in the spotlight.

I don't do that with my savings either. My debit card is not connected with my savings account where most of my capital is. It's a separate account that I manually deposit to every time I need money to spend. Losing the card wouldn't create too much of a headache like would be the case if my main savings account would be in jeopardy.
