BlueWallet — summary

BlueWallet is the long-running mobile Bitcoin wallet with both on-chain and Lightning support.

+ Mobile-first Bitcoin and Lightning self-custody.
+ Supports own-node connections (Electrum servers, LNDhub).
+ Multisig and watch-only wallet support.
− LNDhub mode is custodial — only the on-chain and own-node Lightning modes are self-custody.
− Integrated buy/sell uses third-party providers with their own KYC.

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.

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