Description

Why Bitcoiners choose the Coldcard Q?

Next-level security

  • Dual Secure Elements (2SE): Two independent secure chips from different manufacturers store sensitive data like your seed phrase and private keys, protecting against sophisticated hardware attacks.
  • True air-gapped operation: No Wi-Fi, no Bluetooth. All transactions are created and signed offline via microSD or QR codes, virtually eliminating remote attack vectors.
  • Secure boot: Only official firmware signed by Coinkite is allowed to run, preventing malware or tampered software from being installed.

Anti-tampering protections

  • Duress PIN: Opens a decoy wallet with harmless data if you’re forced to unlock the device. Your main wallet remains hidden and secure.
  • Brick Me PIN: A special PIN that, when entered, instantly wipes all data, ideal for emergency situations involving theft or coercion.

Flexible and secure transactions

  • Built-in QR scanner with LED and advanced algorithms for fast, accurate scanning in any lighting.
  • NFC support, similar to the COLDCARD Mk4.
  • Internal storage compartment for spare MicroSD cards, convenient for backup or quick swaps.
  • USB and NFC interfaces can be permanently disabled by cutting a physical PCB trace, adding a layer of irreversible hardware-level security.

Interface and performance

  • Full QWERTY keyboard for fast and precise passphrase entry, perfect for those using long or complex BIP-39 phrases.
  • Large, sharp LCD screen makes it easy to follow each step during the signing process.
  • Dual microSD slots allow separation and simple handling of signed and unsigned transactions.
  • Operates independently via AAA batteries or USB-C power, no need to connect to a phone or computer, ensuring a fully air-gapped environment.
