help Coldcard Q FAQ
How does the Coldcard Q connect to a computer for transactions?
The Coldcard Q is designed as a passive USB-C device, meaning it avoids exposing private keys to online networks. It can be used completely air-gapped by transferring signed transactions via an SD card or NFC.
What physical security features protect the Coldcard Q from tampering?
It utilizes a fully shielded enclosure and an active self-destruct mechanism if the physical case is breached by a hacker. This prevents sophisticated physical attacks, like fault injection or gltiching, from extracting your seed phrase.
Does the Coldcard Q support multi-currency storage or is it Bitcoin-only?
Coinkite designed the Coldcard exclusively for Bitcoin storage, meaning it does not support altcoins. This narrow focus allows the firmware to be highly optimized and reduces the attack surface associated with handling multiple blockchain protocols.
How many seed words can the Coldcard Q securely store?
The device supports standard 12-word and 24-word BIP39 seed phrases for generating your private keys. It also includes a duress PIN feature that can point to a secondary seed to protect your main funds during a physical robbery.
