Thanks for this under 5 minute primer. Those 90+ minute ColdCard "tutorials" by the KZbin high priests of Bitcoin are probably doing more harm than good to your product by making the hardwallet process look much scarier and daunting than it really is.

whos here after ledger fucked everything up with their new ledger recover service? lol

[@dlukton]

I ordered a coldcard wallet a few days ago, but I have a suspicion that they're back-ordered, and that I'm going to have to wait awhile before they ship it to me.

[@depnox]

yeah, the problem with adding opt-in features via firmware updates is that the capability/vulnerability is then baked into every device. it would have served them better to create a new product with the recovery features.

Ledger taught us (by accident) that all hardware wallets can easily get access to your private keys. The only answer is multi sig to protect against single point of failure.

[@hal7703]

I helped both my mom and dad set up theirs up. At 2:43, I’ve run into the same problem with both of them. Coldcard is plugged into computer and my screen looks like the video. When I click scan, it says ‘no hardware wallets found.’ If you want everyday users to adopt your product, you need to make it more user-friendly.

[@Varias_Variaveis]

Good video. But one doubt remained. How do you send a fund from a specific address to another address? In other words, can you select an address with background, among several, to send via MK4? Thanks.

[@jacksmachine1874]

Sparrow is far more complex then what is shown! When going to download it the website says you will need GPG and then says you need to 'sign the release' but doesn't explain any of this.. So annoying. How the hell are you guys expecting to onboard people if only ultra nerds can figure out how to use this? Or at least have complete guides on what is supposed to be done.

[@kalan91]

Does wallet password (at 3:03) work like passphrase in Ledger, or hidden wallet in Trezor functionality? So that even if your seed words get compromised, you still need that extra password to recover the wallet?

[@krischurchill3387]

Can you transact without a computer? Like all the same but plugged into your cell?

[@pachmann4869]

once you create the PIN, is that PIN forever the only way to access that coldcard? It can't be wiped to factory settings? So in essence, the PIN is worth about $150 (the cost of the coldcard)?

[@thealexgalaxyoriginal]

Good question. I think I will test this

[@BITCOINLENNON]

mine keeps saying 'NO HARDWARE WALLET FOUND' why? please help

[@pomme4moi]

Have they made it easier to upgrade the firmware? Used to be a nightmare.

[@ogikilla]

I got this a year ago and tried to use it, but my brain won't let me understand this. I get you need it to send, but when receiving, its receiving via the wallet created on sparrow wallet. What role does the wallet play when receiving btc, if it only goes into the sparrow wallet? Its a total newb question, but any info would help.

[@rolandovilleta]

When you click receive bitcoin it will display address that was generated by your wallet, wether you receive it through sparrow or any other software those addresses belong to your wallet. Sparrow wallet just allows you to interact and broadcast transactions.

[@jessicgustavsson5837]

Yeah before I even read your comment I said to myself the tutorial skipped that and should’ve added a note on the video explaining that

[@taym2720]

@@rolandovilleta Where is the bitcoin I recieve going to be stored? On the sparrow wallet or my coldcard device?

[@rolandovilleta]

technically the bitcoin is not stored in a software or device, its stored in the wallet that you created (12 or 24 words) so if your cold card breaks or you lose access to sparrow, you can take your wallet (12 or 24 words) and input those words to another software or cold device and load up your accounts again @@taym2720

Can you set up the COLD coldcard without plugging into a computer?

[@CoinkiteInc]

Yes, you can! We call this the air-gap method

[@XKXKIXKXK]

That's what I thought but the video instructions indicate you must be connected via USB. Why advertise as air-gapped if you have to connect via cable?

[@specialagentsynth4316]

are there any size differences between mk2 vs mk4? asking because I'd like to buy the hard case available on your website but only if it fits mk2

[@CoinkiteInc]

Yes, It should fit!

[@paralellosll3849]

So none of the bitcoin are stored on the ColdCard Mk4, they are stored on the Sparrow Wallet?

[@Duke-511]

Bitcoin is always on the Bitcoin network. Your hardware wallet securely holds your 12 or 24 seed words that gives you control over your Bitcoin on the network. The hardware wallets also will sign transactions using those seed words.

[@coltonkinder1424]

How secure is using the Mk4 in this way? Any real risk of compromise?

Extremely secure! Checkout our specs here: coldcard.com/docs/coldcard-mk4

Air-gapping with a MicroSD card instead of a USB cable allows you to transact without ever having to plug in your COLDCARD to any internet-connected device :) For a complete list of compatible software wallets, please refer to this table: coldcard.com/docs/compatible-wallets

[@InAVanByTheRivr]

Either you use a computer, or the wallet is a computer. You can't interact with bitcoin offline. It's actually better that the coldcard is not a complex computer. It's just a simple device by design. It reads potential transactions that you securely import into it offline, if you like the transaction you sign them using the device. The exported info contains the signed transaction which the computer can send out to the internet without having the device connected.

[@scubasteve4119]

@@overbuiltlimitedwhy do you say this? After writing this how is your experience with it now?

[@overbuiltlimited]

@@scubasteve4119 Several reasons. This was several years ago so don't remember a lot of detail. What I do remember was: Far too many steps to do anything on the wallet. The menu system is very deep. Too many features, and many of them "hidden." BTC Sessions walk through was two hours long and still didn't touch on many of them. Time locks. Distraction wallets, secondary pin codes. How many of these features will you actually use? Some of these are a damn good way to lock your Bitcoin from yourself. I went through the trouble of learning the wallet and received test amounts on the wallet. This was to be my super secure wallet that held the bulk of my BTC. I'm not going to be accessing it on a monthly or even yearly basis. In five or ten years I would have to learn how to use it all over again. Then I imagined trying to teach my wife how to use it. Forget it. Bought several Bitboxes and didn't look back. The Cold Card goes unused. Been in since 2016. I've used many of the hardware wallets out there. The Cold Card was the most difficult to use by a large margin.
