Both wallets are Bitcoin-first, but they reach the air-gapped goal differently. Coldcard Mk4 at $148 uses microSD cards for PSBT signing and supports deep multisig coordination. Blockstream Jade at $64 uses a camera to scan QR codes for air-gapped signing. Mk4 has more advanced features; Jade wins on price.

Pick the Coldcard Mk4 if you want microSD-based PSBT workflows and advanced multisig support. Pick the Jade if you only hold Bitcoin (or Liquid), want camera-based QR signing, and prefer a $64 entry point over $148.
