Alternatives to Keystone
Air-gapped QR-signing hardware wallet
Keystone ranks #3 of 12 in Hardware wallets, with an Alt Score of 85. It is licensed under MIT, sold as a one-time purchase from $149 and available on iOS and Android. 12 of 12 checklist rows are verified against a public source.
Crypto holders and institutions who want maximum protection for private keys and are willing to pay $149+ for a dedicated, fully air-gapped hardware wallet instead of a USB/Bluetooth device.
The Keystone 3 Pro: an air-gapped cold wallet with three independent EAL6+ certified secure element chips, a 4-inch touchscreen for on-device transaction verification, open-source firmware, passphrase/hidden wallet support, Shamir and multi-seed backup, BIP-129 multisig support, and the Keystone Nexus companion app (iOS/Android) plus QR-based integration with MetaMask and other software wallets covering 5500+ cryptocurrencies.
All signing happens offline: transactions are transferred to and from the device exclusively via animated QR codes (no USB, Bluetooth, or WiFi for transaction data), so private keys never touch an internet-connected machine. Users pair the device with the Keystone Nexus mobile app or third-party wallets like MetaMask, Sparrow, or Electrum, review full transaction details on the device's own screen, and scan a QR code back to broadcast the signed transaction.
