coldcard Q is officially my favourite hardware wallet. this feels cyberpunk af. Super easy to import a multisig wallet from nunchuk via nfc. Finally have an nfc signer with a screen. keyboard is so satisfying.
Discussion
Mine is on its way
I ordered 2 of them, but no word on when they will be ready for shipment.
I ordered mine in Feb ‘23. Hope it ships soon:)
I guess the regular coldcard can do this too but the nfc was really hard to get working so I never used it. This one is much more forgiving, and is battery powered for portability.
The main downside right now is that it can’t seem to confirm if a multisig address is mine, so I had to use my bitcoin-core node to do this 🤔. Maybe gap limit issue? Because this wallet has seen some use. Might need an sd card for saving this state?… nostr:npub1az9xj85cmxv8e9j9y80lvqp97crsqdu2fpu3srwthd99qfu9qsgstam8y8
Dang, too chonky to fit in a micro pelican case. 
I like the squishy keys because they're likely immune to the "they can hear your password" hack. (Works on regular keyboards I believe.)
Cypherpunk as fuck, but not good for mass adoption
i want one!
Stahp makin me spend my sats, Will 😩
Real question is what is nostr:npub1h50pnxqw9jg7dhr906fvy4mze2yzawf895jhnc3p7qmljdugm6gsrurqev cooking
espresso
That looks amazing and makes me want one myself for my trusted hardware wallet.

Will, can you please share with non techs how one sees that a hardware wallet is not pre loaded with malware?
Is that even a concern in any way?
I love it that cold q is made in Canada.
Compared to: Fiat devices. They scam us, yes, but the legal systems pretend to hold them liable and that gives people small relief until they face the music.
What open source software does an initial scan? Any?
Trying to learn.
At the end of the day using a hardware device is going to be way more secure than exposing your private key to a general purpose computer.
If vendor and supply chain attacks are in your threat model, then use multisig, otherwise single-sig + passphrase with an airgapped coldcard device should be ok and is simpler to backup over long periods of time. This was my goto-recommendation for ages but I’m not sure how long that will be if supply chain attacks ramp up.
Alternatively you can just do a 2of2 or 2of3 multisig with two different hwws and a tapsigner for convenience. Just make sure to have plate backups for both wallets stored in two physically separate locations.
This is a bit more complicated, this is why Ive always like the simplicity of singlesig + passphrase. Passphrase acts like a two factor in case the physical security of the seed is compromised.
As for generating a singlesig key in 2024, i would use coldcards dice-entropy feature. Depending on your level of paranoia I would verify the algorithm a few times on a computer to make sure it’s not back-doored or something (sha2(dice roll string)), doing the final run without the verification step, as that would expose the key to a general purpose computer.
Thank you Will. I appreciate it.
I will review these notes carefully before asking further.
🤙🏽
Don't forget to backup the pubx of the multisig or you can't restore it :)
Wow! This looks really nice 🤙
Looks really great, but source viewable feels just not right.
I would love to try one of these! nostr:npub1az9xj85cmxv8e9j9y80lvqp97crsqdu2fpu3srwthd99qfu9qsgstam8y8
Bitcoin only though 🙄😆
I want to move my btc into something more secure. Bear with me, still learning the ins and outs of Bitcoin storage options. What is the difference between something like this and one of those trezor hardware wallets? Does this also store your bitcoin? Will this scan a lightning dress qr code and let me purchase something with Bitcoin?
Thanks 🫠 
Now if only you had something of value to put in your wallet.
Patiently awaiting mine 😍
So envious! I can't wait for mine to arrive!
This is not going to help mass adoption one bit
Why can’t someone use their talent to make something that’s actually user friendly enough for the average person, like making the iPhone of hardware wallets, elegant, simple and easy to use
With these small buttons it looks like a real PITA to use it... to each his own tho... As long as you like it and you happy with it. I don't really see/feel the need for it
I need to try out one of these!

dude i had resisted this one But the vid looks so sweet
Looks complicated
Would be interested in Coldcard if it was open source. 🤷♂️

Can’t wait for mine. Coinkite products have been top notch thus far
want
I remember when I ordered a mk1 and the capacitive buttons were shit. I told support I had problems with phantom button presses and unresponsiveness they blamed the usb cable i was using. I told them I was using an Anker cable. They told me they weren’t aware of that brand and to buy a name brand cable. 🤣
Considering it
looks solid AF! Now I want one too. Wen???
ColdCard needs to work on its UI & user experience & I say this as a ColdCard user.
Calling it cypherpunk or retro now in 2024 just seems like an excuse to defend the software design in 2024.
All that screen & it still looks like people need to know how to compile a project from GitHub. 😂
Even the list of options still look tiny for the screen size, it’s basically a bastardised version of the MK4 firmware, slightly enlarged, it’s not taking advantage IMO of the large screen.
They need a UI designer & someone who can create a look & feel that is both more modern & more user friendly.
Just my thoughts. 🫡
That's fantastic to hear! Coldcard is indeed a favorite among many for its security features and cyberpunk vibe. Being able to import multisig wallets via NFC and having a satisfying keyboard adds to the overall experience. It's great to see hardware wallets evolving to meet the needs of users in the ever-changing landscape of digital assets and security.
Can you sign for multiple wallets or still just the one?
Can’t wait to get mine❤️💪🏽
they available in Canada yet?
Blackberry robbery?
