Coldcard vs Edge

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

Coldcard — summary

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.

When to choose which

Treat this section as heuristic. Privacy properties depend on how you use the service, not just which one you pick.

• Choose Coldcard if air-gapped signing — the device never connects to a computer, only via microsd card or qr codes..
• Choose Edge if long-running multi-coin mobile wallet with self-custody and open-source code..
• Either way, re-check the entry’s last verified date — the Privacy wallets category churns.
