## Verdict

Coldcard is the air-gapped Bitcoin-only hardware wallet. Purchase with crypto and ship to a forwarding address and the manufacturer never sees an identity. The Bitcoin-only firmware is the defining choice — narrower attack surface, no multi-coin features. Best fit for users who hold Bitcoin and want a hardware wallet that does Bitcoin only.

## Strengths

- Air-gapped signing — the device never connects to a computer, only via microSD card or QR codes.
- Bitcoin-only firmware reduces attack surface compared to multi-coin hardware wallets.
- Manufacturer accepts crypto payment and ships pseudonymously.
- Reproducible firmware builds.

## Caveats

- Shipping address binds the device to a physical location; using a forwarding address or PO box is the standard pattern.
- The Coinkite operator is Canadian; legal jurisdiction matters for the corporate, not for the device.
- Bitcoin-only — not appropriate as a multi-coin hardware wallet.
- Facts need re-verification by operator (last seeded 2026-01).

## What Coldcard is

A Bitcoin-only hardware wallet built around air-gapped signing — microSD or QR code, never USB.

## Threat-model fit

When Bitcoin-only and air-gapped are both binding requirements.
