Best open-source hardware wallets

Trezor Safe 7 is Trezor's premium flagship for users who want auditable secure-element architecture, post-quantum firmware authentication, Bluetooth, wireless charging, a large touchscreen, and optional Bitcoin-only firmware, but it is expensive and not air-gapped.

Blockstream Jade Plus is the stronger current Jade choice for Bitcoin users who want open-source verification, a larger screen, improved camera, QR/JadeLink air-gapped signing, air-gapped firmware updates, multisig, and stateless workflows.

Blockstream Jade Core is the simplified $99 Jade for Bitcoin beginners: open-source, battery-free, USB-C/Bluetooth based, and easy to pair with the Blockstream app, but it lacks Jade Plus's camera, QR air-gap, and JadeLink features.

Trezor Safe 5 is one of the strongest balanced hardware wallets for users who want open-source firmware, secure-element protection, a color touchscreen, haptic confirmation, privacy tooling, and advanced backup options without relying on Bluetooth or proprietary wallet lock-in.

Passport Prime is Foundation's premium open-source Bitcoin and personal-security platform, adding KeyOS, touchscreen UX, QuantumLink Bluetooth, NFC KeyCards, FIDO2, 2FA codes, encrypted storage, and app sandboxing while introducing more complexity than Passport Core.
