BitBox02 vs Coldcard

Both are listed in Privacy wallets. The table below pulls directly from each service’s data sheet; see each entry for sourcing.

BitBox02 — summary

BitBox02 is the Swiss open-source hardware wallet from Shift Crypto.

+ Open-source firmware with reproducible builds.
+ Two product lines — BitBox02 Multi-edition (BTC + others) and Bitcoin-only edition.
+ Swiss operator; cryptography reviewed publicly.
− Shipping address binds the device to a physical location.
− Smaller ecosystem of third-party wallet integrations than Trezor or Ledger.
− Swiss operator jurisdiction.

Coldcard is the air-gapped Bitcoin-only hardware wallet.

+ 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.
− 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.
