5 Reasons to Get A Coldcard MK4
1) With the Coldcard MK4 your bitcoins are safe against hackers
You can use the Coldcard MK4 fully air-gapped. Information is transferred from and to the device with a Micro SD card.
This means that the hardware device will never be directly connected to an online device. There is literally a gap of air between your hardware wallet and the online world.
An Air-gap is the optimal way to secure your bitcoins against hackers. It is no rocket science that a separation layer of air will keep every electrical signal out. It’s like a deep ditch with hungry crocodiles around your concrete bunker!
2) You can protect your bitcoins against robbers and burglars
With the Coldcard MK4 you can set anti-phishing words between your two pin codes and set a ‘brick me pin’. If someone changes your device with a fake device to steal your pin. You will notice it before inserting the second pin.
The Coldcard can even protect you if someone tries to rob you. You can give a wrong pin that bricks or resets the device OR brings the attacker to a fake wallet.
If a thief takes your hardware wallet and tries to crack it. It will be near impossible to get your seed. He would have to crack both of the secure elements that are created by different vendors.
Cracking one secure element is extremely expensive. Even trying is only feasible for intelligence agencies.
3) You know your Coldcard device is genuine when it arrives
The Coldcard MK4 comes in a sealed bag with a unique number. You can find the same number in the device. This number is stored in the OTP (One Time Processor). Once set in the factory, it can’t be changed.
If you check this number it will give you certainty that the hardware wallet in your hand is the same device that is send from the factory. Further, it proves that the device is turned on for the first time and that the firmware is legit.
If there is something wrong with the firmware, the red caution light will light up instead of the green light.
4) You know your backup seed is created securely
Your backup seed is the key to your bitcoins. It shouldn’t only be kept safe. It should be created securely too. If there is not enough entropy or if the RNG (Random Number Generator) isn’t random enough. Your seed can be brute forced.
A seed in the Coldcard is not created by one RNG, but by three! This means that all three RNGs have to be flawed or compromised to endanger your seed.
Even if you don’t want to take this tiny theoretical risk. The Coldcard enables you to roll ’n dice 100+ times. You insert the values into the device and you know for certain your seed is solid as steel!
5) You can use the Coldcard MK4 for advanced seed management
With the Coldcard MK4 you can manage multiple seeds for yourself, family and friends or for a company. You can do this using BIP-85 and Seed Vault. You can use them together too.
With BIP-85 you can make child seeds from a master seed. If you keep the master seed secure, you will always be able to recover the child seeds. These child seeds can be Bitcoin seeds in the same or different format. They can also be seeds for another protocol like Nostr. Yes that’s right. You can create Nostr seeds with the Coldcard
With Seed Vault you can create and store multiple seeds beside the original seed. The seeds are not stored in the secure element, but they are encrypted on the device. Encryption is done with the original seed, which is safely stored on the secure element. Beware, Seed Vault is an advanced feature, only use it if you know what you are doing!
