Important, August 2026<\/strong><\/p>\n

A bug has been found in the Coldcard firmware that causes seeds generated on the device prior to version 5.6.0 to be weaker than intended. Be sure to update your Coldcard MK4 to version 5.6.0 or later before generating a seed. If you\u2019ve already generated a seed, you\u2019ll need to create a new one: updating the firmware alone will not fix an existing seed.<\/p>\n

What if you have a Coldcard MK4 lying around, but right from the first boot-up, you get the feeling that this isn't a device that forgives mistakes? That feeling is right. The MK4 isn't built to be user-friendly. It's built to keep your keys offline, even when you're in a hurry.<\/p>\n

I love that. Not because it\u2019s easy, but because it\u2019s fair. A Coldcard forces you to work carefully, write down your seed phrase properly, and think about what self-custody really means. Crypto is noise. Tools like this aren\u2019t.<\/p>\n

This guide shows you how to set up the Coldcard MK4, from the initial startup to a fully functional wallet. The sales context has changed, however: the MK4 is not the current Coldcard model being sold here. If you're looking for a working model today, you're better off checking out the Coldcard Q<\/a>. For other options, you can also hardware wallet's product line<\/a> view.<\/p>\n
