Great video. Going to use this when setting up my coldcard. FYI - If anyone is wondering about the screen flickering on the coldcard, it's to do with the frame rate the video was shot at not the screen itself.
👍Best review. Unique wallet. A study in productive paranoia. Not for the weak minded. Lots of details. Thank you for taking us through the looking glass. This must be the most secure BTC wallet in existence. There is relatively little information about this wallet when searching TH-cam. You did a valuable video. Thank you.
Your tutorials are outstanding. Your generosity is one for the record books. Your dedication shows through your obvious talent. Thank you sir for all that you do.
I am currently waiting on the Mk4. First hardware wallet I've ever bought. Ngl I was scared because I do not consider myself a technical guy. This video is a great tutorial for plebs like myself. TY for your work Ben, I tipped some sats over strike.
Nice one. Coldcard remains the most reliable hardware wallet in the market IMO. Ledger, Trezor, Passports, Bitbox, meh. Gimme a Coldcard. Mk3 or Mk4. If you know enough about who is making them, how they're made and how you can verify... good way to go. Don't trust tho, verify.
Es el mejor tutorial explicativo que me he podido encontrar en internet. Me ha costado entender algunas cosas porque no hablo muy bien el idioma pero, lo cierto es que en español hay poco contenido sobre esta hardwallet. Aún así, lo has puesto muy fácil y muy claro, te lo agradezco. Espero que siga creciendo tu canal porque aporta mucho valor, yo me suscribo. Un saludo.
encrypting a backup of the seed phrase onto an extra sd card requires knowing another multi word password.. ...so you're hiding your private key with another long password. can someone please explain why to do this? it sorta makes sense, but i can't explain why
I see the coldcard can come bundled with more than one SD card. Are these spare cards in case one goes bust, ore do more than one SD card serve a purpose?
Underrated and subscribed. I was wondering when you are carrying a partial transaction from your PC to your wallet for signing, is there a way a malware can be carried into you wallet that steals your private keys? Great video btw. It's people like you, that are educating others on the strengths of Bitcoin and how to utilize it, that make the difference. 👍
Thanks for the comment, and great question! The keys are segregated on the device to prevent this. My understanding is that the SD card doesn't have access to the keys, only the finished signed transaction. I'll perhaps defer to Rodolfo at coinkite for clarification on this though.
High quality video content! I have another question: someone transferred me some usdt and I have recovery phrases. ----------- How can I monetize them?
Relating to the part where you created a backup and then restored the wallet using that backup: didn't you say it was an encrypted backup? I didn't see you enter a passphrase or decrypt anything. Did i miss anything? What could a person who found the file or the wordlist do with it? Or is it that the backup file is an encrypted file and the wordlist is the key to decrypt it? Probably that now that I write and think about it. I'll leave the comment in case it wasn't clear to anyone else.
@1:14:05 what gets actually saved to the SD-card @ setting up BIP-85 derived secret? The plain-text 12-word seed unencrypted? And what is the use case of this saved file? Where do I have to store it (in comparison the backup of Coldcard is in an encrypted file...)
@BTCSessions - noticed when using air gapp to create a Sparrow Wallet with ColdCard your exported the generic JSON however, now ColdCard has a Sparrow Wallet export...do you now export that instead of the generic JSON from ColdCard? Thanks
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.
Appreciate the detailed breakdown! I need some advice: I have a SafePal wallet with USDT, and I have the seed phrase. (alarm fetch churn bridge exercise tape speak race clerk couch crater letter). Could you explain how to move them to Binance?
Does anyone know what this part at 23:20 is? I am trying to setup XPUB for pocketbitcoin recurring purchases, and in their tutorial they say you should use account number 1 for pocket when exportting your wallet with generic json. I don't understand why that is? Are account numbers just other bitcoin public addresses or?
My understanding is that it's the "pathway" used to generate addresses. Your hardware can generate a massive number of bitcoin addresses, and you need to decide which ones your wallet starts from. Changing the account number from blank (technically account 0) will change your starting point. When pocketbitcoin says account 1, they likely mean just the default pathway.
Thanks for the tutorial. Do you know if in the coldcard is possible the see the seed phrase in case you lost the paper you noted to? The Trezor and others is not possible to do that. regards.
Is there any reason at all that it wouldn't start up after you've plugged into an adapter (lights are on both adapter and cable connection)? Is there something I'm missing here? Or have I received a dud?
I am wondering about the Sparrow steps taken before the initial opening of the Sparrow app in this video. I see at the bottom of your app screen there is a slider that is blue, and before that it can be yellow. How do you go about learning that part?
Yeh, I didn’t see that either and couldn’t understand why my btc was not showing up in the wallet. Then thought I would just hit the toggle button which was off when the app was downloaded and voila, the btc had arrived which was a huge relief
Thanks for the video. I am trying to sign a transaction, and I see a “change back” address. The amount is drastically less than the difference between the amount I’m sending and the amount I should have left over. Can you explain what the change back address and amount means?
When you first received BTC into the ColdCard wallet I did not see where you saved the PSBT to your SD card and then loaded the SD card into the Coldcard for signing? I have been trying to do this with my Sparrow Wallet (on a MacBook as well) and a ColdCard (MK4 with the latest Firmware) and I keep getting the error code: "Failure. My XFP not Involved". I Checked my Coldcard Master Fingerprint and my Sparrow wallet for the cold card and they have the same fingerprint...Any thoughts?
Assuming you have a bricked Coldcard. Once you import your seed phrase and as long as you have the correct identity, can you use the existing Sparrow wallet(s) that you have created? Coinkite tell me I need to know the path???
Thank you for this comprehensive video. Is there any difference between cloning the cold card and simply putting in your 24-word seed into the new cold card?
No worries! So cloning will basically copy all your settings/preferences PLUS any items you have in a new feature (which I made a video on) called seed vault. Importing the seed is fine as well, this just streamlines the process and grabs any additional info you've imported.
wish you could have explained the different options for the decoy wallet. Would have been nice to hear more about the "brick" that you keep referring to. What does this mean>? What is the point of having a Brick Cold Card, as you nor anyone can access it? You didn't explain that part but you went on and on about the very obvious implications of a $5 wrench attack...
Why is the Micro SD card not a threat to the “air gapped” setup? Yeah the hww was never directly connected to the internet but the micro sd was in the cpu then into the hww? I don’t understand lol
@@yee-7o7 so apparently with the micro SD, you can actually view the files on SD card before you put it into the cold card. A usb, doesn’t allow you to do this. Hopefully this makes sense.
@@yee-7o7it’s a .json file which is basically text you can audit it if you choose and you can check your micro sd to see what’s on it. Air gapped means the hardware itself never goes online.
we are putting a micro sd into an airgapped device, then removing it and putting it into a computer that is online, then we remove it and put it back into our "air gapped" device. i dont get it how this doesnt comprimise things.@@suertetattoo5771
Hey BTC Sess, my Mac won't open the dfu file in order to upgrade firmware. Any suggestions. it just opens a blank document and if I search for a file too open it nothing happens.
I have my mk4 coldcard with wasabi as my desktop wallet but I’ve been hearing disappointing news about wasabi regarding privacy. If I want to switch over to sparrow wallet, do I simply initiate an import to sparrow wallet as was done in the video? From there would I need to do anything else with wasabi in order to access my stack?
You're exactly right - simply import and you're set! Regarding Wasabi, I was also disappointed. However, it only pertains to the coinjoin function of the wallet - so if you opt to use it as a basic desktop wallet it will still function with the same basic privacy. That said - Sparrow is awesome.
I really appreciate your efforts! A bit off-topic, but I wanted to ask: I have a SafePal wallet with USDT, and I have the seed phrase. (alarm fetch churn bridge exercise tape speak race clerk couch crater letter). How can I transfer them to Binance?
FABULOUS video! May I ask that you do a "How to buy bitcoin video using ColdCard and Bitwell Bitcoin"? I see Bull Bitcoin does not have the etransfer feature working on their site right now. Might be another option for Canadians. :-)
The password with wasabi is just to unlock the desktop software itself if I'm not mistaken. It has no bearing on the actual seed phrase of your Coldcard. It's basically a mechanism to prevent someone from auditing your balance if they get access to your computer.
@@BTCSessions thank you for the reply. I have gone through your tutorials and checked out everything cold card has put out and I didn’t know if it encrypted via the 25th word which would make it incompatible with 24 word seed wallets, which is my concern. I haven’t been able to find a solid answer
@@se6586 so with Coldcard, you put your 25th word into the hardware itself, then you can access it from any 3rd party wallet software. I would not add anything else outside of this, as it can complicate things and possibly result in user error.
On the passphrase section when it gives you the option to save to SD card, that is to save the actual passphrase. It's not to save the xpub for exporting to another wallet.
If you save the passphrase does that mean you don’t have to type it in when using your pin? It will auto add the passphrase to switch to the correct wallet?
Have you heard anything about Tangem wallet? it's cold hardware wallet that looks like a regular credit card and the keys are stored in it. Would love to see a review from you on the wallet
Great Video. Question - I was going to buy this wallet and some accessories but there's only an option to pay with a Gift Card or with BTC. Where can I buy these items using dollars?
watching your videos form last year ,Thank you for giving so much valuable information . I have a silly question in my mind , if i create sparrow multisig wallet , and for some reason government take down sparrow and electrum , then how can i restore my multisig ?
Thank you Ben, what wallet would you recommend for the phone. Would that work on a De-Googled Pixel phone? Regarding using the Coldcard with Sparrow are there any special provisions that need to be made for PC's that are running Linux Ubuntu 22.04?
Anyone else receive a coldcard that says “Bag Me Now” at first power on? I assume it means it wasn’t setup properly prior to shipping and I’ll need a replacement. Hopefully product support is good.
If it breaks I put your wallet to a new one, if they go out of business then you can just get a new cold storage wallet if you want and transfer your btc to it
Great video thanks. Question,: I developed a habit to the LIVE mobile interface where I could view my bitcoin. Is there any mobile interface I can use with Sparrow to see my BTC on mobile? Thanks!
I had previously purchased a Trezor Model T, via the referral link, after watching your video's a little over a year ago. However, I don't have a backup hardware wallet, so I was looking to purchase one. After watching your Top 6 Bitcoin Hardware wallets of 2022, I narrowed it down to the Coldcard or the Keystone. After watching both of your detailed usage videos on each of the two, I am leaning more toward purchasing the Coldcard Wallet (via your referral link). Then after copying the wallets created on the Trezor to the Coldcard, I plan to wipe the Trezor and have it as the backup as it is less secure than the Trezor due to the Coldcard being air-gapped. Thanks once again, Ben!!! One question: Would you recommend using the Micro SD over the Virtual Disk with the Coldcard?
Awesome Video Ben! Thank you! I received my Cold Card and walked my way through with your help. I appreciated the discount that I received by using your link when purchasing it. I chose to use unsigned transactions with the micro USB as it is the most secure being totally air-gapped. When Sparrow Wallet supports NFC I will switch to NFC.
hi dude quick question for you. After signing the transaction on coldcard, and loading the signed transaction to sparrow, there is no "broadcast transaction" button available for me, it shows "save final transaction" instead. Any way to get past this?
Really appreciate the helpful and informative content you put out. I am considering a Mk4 but have a new Keystone 3 Pro which I was planning to use for BTC alone to HODL only. When Keystone release their dedicated BTC firmware next year, will the Keystone be comparable to a Mk4 in terms of security? I will use a Tangem most likely for daily transactions of I do any. Many thanks 'eh :)
Hello BTC Sessions. I am having trouble with sparrow wallet not recognizing my Trezor as the second signer in my multisig, I am unable to move my BTC. Any suggestions on how to fix this problem?

One more priceless video. Thank you so much!
This was massively helpful!
Great Video. Question - I was going to buy this wallet and some accessories but there's only an option to pay with a Gift Card or with BTC. Where can I buy these items using dollars?
Hi Ben can you use a regular wall usb c charger yo turn on CC?
Is seed XOR basically the coldcard's version of shamir?
Really appreciate your tutorials, thank you very much
Complete newb question... migrating here from ledger, so ty for this video. Can I use a USB C cable plugged in to mains rather than battery?
watching your videos form last year ,Thank you for giving so much valuable information . I have a silly question in my mind , if i create sparrow multisig wallet , and for some reason government take down sparrow and electrum , then how can i restore my multisig ?
amazing tutorial. thank you so much!
Thank you Ben, what wallet would you recommend for the phone. Would that work on a De-Googled Pixel phone? Regarding using the Coldcard with Sparrow are there any special provisions that need to be made for PC's that are running Linux Ubuntu 22.04?
Anyone else receive a coldcard that says “Bag Me Now” at first power on? I assume it means it wasn’t setup properly prior to shipping and I’ll need a replacement. Hopefully product support is good.
Thanks for your time, and expertise!!!
Hi mate, noticed that when I recieved my CCard the 2 Micro SD cards came each in a simple zip lock bag.. not sealed.. Is this ok..?
Shouldn’t matter you can format them if you’re worried
I am using an old MacBook which might die soon. If my computer fries, how do I back up my cold card so I can use sparrow on my new computer?
What do you think about Tangem wallet? About to buy Coldcard but saw some people hyping this one?
What happens if this device breaks? Company goes out of business? Are these worthy concerns?
If it breaks I put your wallet to a new one, if they go out of business then you can just get a new cold storage wallet if you want and transfer your btc to it
Can we use a windows computer to do this
What happens if I lose my MicroSD card or what if it breaks?
You better have you 24 words, pin and other two words written down.
Great video thanks. Question,: I developed a habit to the LIVE mobile interface where I could view my bitcoin. Is there any mobile interface I can use with Sparrow to see my BTC on mobile? Thanks!
I had previously purchased a Trezor Model T, via the referral link, after watching your video's a little over a year ago. However, I don't have a backup hardware wallet, so I was looking to purchase one. After watching your Top 6 Bitcoin Hardware wallets of 2022, I narrowed it down to the Coldcard or the Keystone. After watching both of your detailed usage videos on each of the two, I am leaning more toward purchasing the Coldcard Wallet (via your referral link). Then after copying the wallets created on the Trezor to the Coldcard, I plan to wipe the Trezor and have it as the backup as it is less secure than the Trezor due to the Coldcard being air-gapped. Thanks once again, Ben!!!
One question: Would you recommend using the Micro SD over the Virtual Disk with the Coldcard?
Awesome Video Ben! Thank you! I received my Cold Card and walked my way through with your help. I appreciated the discount that I received by using your link when purchasing it. I chose to use unsigned transactions with the micro USB as it is the most secure being totally air-gapped. When Sparrow Wallet supports NFC I will switch to NFC.
Anyone else buying the dip? Now’s the time!
export json file include public key only?
hi dude quick question for you. After signing the transaction on coldcard, and loading the signed transaction to sparrow, there is no "broadcast transaction" button available for me, it shows "save final transaction" instead. Any way to get past this?
just realized i had to toggle on electrum
Thanks Ben
Fantastic tutorial ben! Do you not recommend verifying coldcard firmware
Great video. And you accent is awesome. Unfortunately we dont have good tutorials like this one in portuguese.
make one? Brazil and Angola need your help
Nice Tutorial !!
Had a question - does it work with Exodus wallet?
Appreciate inputs. Thanks.
Really appreciate the helpful and informative content you put out. I am considering a Mk4 but have a new Keystone 3 Pro which I was planning to use for BTC alone to HODL only. When Keystone release their dedicated BTC firmware next year, will the Keystone be comparable to a Mk4 in terms of security? I will use a Tangem most likely for daily transactions of I do any. Many thanks 'eh :)
¿Is there any way to verify that the manufacturer of this device actually delivers on what they promise and the cold card is actually safe?
Ben, My MacBook Pro is my desktop. It has no port to receive the micro SD card. What to do?
U can buy a usb or usb c micro sd reader
Does this coldcard only work for BTC or can it be used with alt coins? Thanks
Have you tested mk4 NFC transactions?
I didn’t purchase the SD card is that necessary and, if so, why?
Watch the video
