Warning: This device is Bitcoin-only. Your toxicity might increase upon purchase.

Do one thing – and do it well.

This is the spirit with which the Coldcard Mk4 wallet has been developed.

Coldcard owners know what they’re getting – the best in its class.

Every purchase comes with a complimentary free consulting session with our cybersecurity consultants to assist you in setting up your device and backups the correct way.

Further information:

This wallet gives you full control over your bitcoins. This means no third party can freeze or lose your funds. You are however still responsible for securing and backing up your wallet.

Coldcard has been embraced and integrated by team Nunchuk  around Hugo Nguyen, Vietnam’s first (known) contributor to the Bitcoin protocol.

Coldcard is an easy to use, ultra-secure, open-source and affordable hardware wallet that is easy to back up via an encrypted microSD card. Your private key is stored in a dedicated security chip. 

This wallet is loaded from a secure specialized environment provided by the device. This provides very strong protection against computer vulnerabilities and malware since no software can be installed on this environment.

Original Coldcard Mk4 hardware wallet – imported from the cypherpunk-leaning Bitcoin OG firm Coinkite from Canada.
