Why choose Coldcard MK4 for Bitcoin storage?

Not multi-coin, extra security

Unlike multi-currency wallets, Coldcard MK4 supports Bitcoin only — eliminating vulnerabilities found in other blockchain protocols. The result is a minimalist yet extremely secure and specialized hardware environment.

Advanced hardware security

Built with the Secure Element ATECC608A, this chip is dedicated to securely storing your private keys, protecting your funds even in the event of physical theft.

  • Duress PIN: Access a decoy wallet under coercion.
  • Brick Me PIN: Permanently disable the device if forced to unlock.
  • Anti-phishing Words: Detect cloned or tampered devices.
  • NFC Tap: Secure, ultra-short-range wireless transmission to your mobile device with a simple tap.
  • Virtual Disk Mode: Coldcard can emulate a USB drive, allowing you to transfer PSBT files via drag-and-drop.

Air-Gapped operation – No internet needed

Coldcard uses an air-gapped workflow, enabling you to complete transactions entirely offline. Signing is done via encrypted microSD cards, offering full immunity from malware, keyloggers, or network-based attacks.

Open source & auditable firmware

Coldcard MK4 is fully open-source, empowering the community to audit its code for integrity and transparency, earning the trust of privacy-conscious Bitcoiners worldwide.
