Right now, I can't point to a particular hardware wallet I can vouch for as open source, but one which I am personally looking forward to using is Arculus from chainge finance, Arculus is a hardware which I believe have not started shipping out, but from all I've read about it, it may likely be a great choice, though like I said , I've not confirmed if the wallet is open source or not.
I doubt that Arculus is open-source. According to our
local Croatian hardware wallet topic, it's a credit card-type of device that works only in the USA. You need to use it together with the Arculus app, and the app doesn't work outside of the United States. I don't think you are American, so you should forget about this particular HW.
With governments getting their hands into the crypto industry lately, we should be prepared for the worst. They may compromise the company making the hardware wallet, but if the device is open source, their efforts will be futile in the long run.
I think the biggest concerns will be hardware compromises. We found out recently that Gigabyte mainboards had backdoors installed. I think that will be a huge problem in the future which could also impact the cryptocurrency industry.
...My choice would be Electrum...
The subject of this discussion is B
est open source hardware wallets for BTC. Because of that, recommendations for software wallets aren't the way to go.
Just to make things clear, Ledger wallet's firmware is not yet open source, and somewhat controversial after the announcement of the ledger recover product.
If you just want to store btc, then the Coldcard MK4 is your best option.
Well, Coldcard isn't open-source either. But unlike Ledger, Coldcard has a public and verifiable codebase.
But there was a time someone on this forum complained of losing funds on an electrum wallet because of not updating to the latest firmware. I don't know if this has been really proven to be true. I have tried looking up google for help but I have not really gotten anything concrete and I would appreciate if someone can help me out.
There is no firmware with Electrum. Many users became victims of phishing scams in the past because they downloaded and installed fake Electrum wallets without verifying the signatures. This is phishing and social engineering, and is a user mistake.
