Source: https://altcatalog.com/alternatives/keystone/ Category: Hardware wallets ## Where Keystone stands out - **Air-gapped / QR signing** — 4 of 12 apps with a verified answer have this ## Overview - **Who it's for**: 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. - **What you get**: 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. - **How it works**: 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. ## Profile - **License**: MIT (verified 2026-07-12) - **Pricing model**: One-time (verified 2026-07-12) - **Starts at**: $149 (verified 2026-07-12) - **Platforms**: iOS, Android - **Status**: active (verified 2026-07-12) ## Ranked alternatives | # | App | Alt Score | Licence | Platforms | |---|-----|-----------|---------|-----------| | 1 | [OneKey](https://altcatalog.com/alternatives/onekey.md) | 93 | GPLv3 (firmware); companion apps under OneKey Source License v1.1 (non-OSI) | Windows, macOS, Linux, iOS | | 2 | [Trezor](https://altcatalog.com/alternatives/trezor-suite.md) | 89 | GPLv3 | Windows, macOS, Linux, iOS | | 3 | [Blockstream Jade](https://altcatalog.com/alternatives/blockstream-jade.md) | 81 | MIT | Windows, macOS, Linux, iOS | | 4 | [Ledger](https://altcatalog.com/alternatives/ledger-live.md) | 81 | Proprietary | Windows, macOS, Linux, iOS | | 5 | [BitBox02](https://altcatalog.com/alternatives/bitbox02.md) | 78 | Apache License 2.0 | Windows, macOS, Linux, Android | | 6 | [Ellipal](https://altcatalog.com/alternatives/ellipal.md) | 78 | Proprietary | iOS, Android | | 7 | [SafePal](https://altcatalog.com/alternatives/safepal.md) | 78 | GNU General Public License v3.0 | iOS, Android, Browser extension | | 8 | [Cypherock](https://altcatalog.com/alternatives/cypherock.md) | 70 | MIT (with Commons Clause License Condition v1.0) | Windows, macOS, Linux | | 9 | [Coldcard](https://altcatalog.com/alternatives/coldcard.md) | 66 | MIT (with Commons Clause License Condition v1.0) | Windows, macOS, Linux, iOS | | 10 | [GridPlus Lattice1](https://altcatalog.com/alternatives/gridplus-lattice1.md) | 59 | Proprietary | Web, Browser extension | | 11 | [Tangem](https://altcatalog.com/alternatives/tangem.md) | 55 | Proprietary (source-available) | iOS, Android | Alt Score = Verified coverage (90%) + Visibility (10%).
