Overview
Editorial assessment
Keystone 3 Pro combines a touchscreen with QR signing and several compatible wallet apps. The coins and functions available depend on the firmware and app. The manufacturer lists both mobile apps and desktop wallets such as Sparrow.
BIP39 and Shamir backup are documented. Before restoring, the backup format, required shares and firmware must match. A fingerprint sensor does not replace a recoverable backup.
The device suits a deliberately configured QR workflow. Before buying, check the specific combination of asset, wallet app and platform. It has no Bluetooth; the available USB connection does not establish support for every wallet app.
A larger screen provides space to review the recipient, amount and other transaction details. What matters is what the app actually displays and what you confirm on the device. A long asset list does not establish support for every transaction type or the same functions in all apps.
Opposite OneKey Pro Keystone shares the touch and QR approach but offers no Bluetooth. Its firmware is classified as partly open in the dataset. If you already use a particular wallet app, check its specific integration before choosing a hardware wallet by individual features.
The Direct comparison ELLIPAL Titan 2.0 vs Keystone 3 Pro puts the two QR devices side by side. The feature table brings together connections, backups and list prices; the linked manufacturer sources explain each workflow.
Pros
- Air gap via QR and microSD
- Touch display and battery
- Multiple Secure Elements with CC-EAL5+ manufacturer information
- Multi-chain including Solana
- Fingerprint sensor and multi-seed
Cons
- Larger touchscreen device; no Bluetooth
- A compatible wallet app is required for each asset; not every integration supports every feature
- Check the backup format and firmware version before restoring
Suitable for whom?
- If you want to combine Bitcoin, Ethereum/EVM and Solana with air gap according to characteristics.
- If iOS is supposed to be supported according to the features and you can get by without Bluetooth and without NFC.
- If a client's open source characteristics are important to you and firmware is partially open source (partially) sufficient.
Who is it not for?
- If you require an official desktop companion app for Windows/macOS/Linux - not intended according to the characteristics (not the same as "desktop unusable").
- If you expect completely open source firmware - according to characteristics only partial.
- If you require Bluetooth or NFC - according to the features, no.
