Hardware Wallets, Model by Model

Entry-level. No Bluetooth, no touchscreen. Solid for users who want a simple device for storing Bitcoin or a small number of assets. The storage limit means you can't install all apps simultaneously - you swap them as needed (assets remain safe regardless).

Mid-range with a touchscreen and Bluetooth. Bluetooth signing via Ledger Live mobile is convenient, but it introduces a wireless channel that the Nano S Plus avoids.

Designed for regular dApp interaction. E Ink screen is more readable in daylight and persists without power, which has practical advantages for checking addresses.

Premium form factor. Same security chip as the Flex. You're paying for the curved display and wireless charging, not a higher security level. NFC adds another connection surface to consider.

Entry-level open-source hardware wallet. The Optiga Trust M (Infineon) provides EAL6+ security. Supports passphrase (25th word) for hidden wallets. Fully open source from firmware to the Suite desktop app.

Mid-range. The TROPIC01 chip is Trezor's own design, open-sourced. This means the security can be verified from hardware level upward - no proprietary chip black boxes.

IP67 water and dust resistance. Post-quantum cryptography ready, meaning it already supports CRYSTALS-Dilithium signatures if/when the Ethereum or Bitcoin networks upgrade. The TROPIC01 chip is the same open-source design as Safe 5.

Each card contains a Samsung S3D350A secure element (EAL6+). During setup, the card generates a key pair inside the chip. The key never leaves the chip in any form - there is no seed phrase. You authorize transactions by tapping the card to your NFC-enabled phone. The second card is your backup: tap it during setup to create a second card that shares the same keys.

Same chip, same design, three cards. The third card gives you an additional backup and the option to distribute cards geographically. Common setup: one card in your wallet, one at home, one in a safety deposit box.

The Ring contains the same Samsung EAL6+ chip embedded in a ceramic/titanium wearable. Tap your phone to your ring finger to sign transactions. The two included backup cards share the same keys. Practical for daily spending on small amounts; store large holdings in cold cards separately.

The Titan 2.0 is the flagship. Its defining feature is the anti-tamper mechanism: if the case is opened or physically attacked, the device erases its keys. Combined with the zero-wireless-connection design, this is designed for adversarial physical environments. 10,000+ supported tokens. The USB port charges the device but carries no data.

Same air-gap principle, smaller form factor. For users who want the security of full air-gap at lower cost and in a pocketable size.

Higher cert level than the Titan lineup. Card-sized with the same QR-only communication. The EAL6+ chip is a notable upgrade for institutional or high-value use cases.

Air-gapped via QR code. CC EAL5+. 30,000+ tokens. The S1 is the most affordable air-gapped hardware wallet on the market. Binance backed, which is either reassuring (institutional backing) or concerning (centralization) depending on your perspective. The X1 model adds Bluetooth, breaking the air-gap principle.

CC EAL7 - the only consumer device at this certification level. Air-gapped, fingerprint authentication, 4" touchscreen. The GRAPHENE metal plate for seed storage is sold as a companion product. For users with high-value holdings who want the highest available certification and are willing to pay for it.

Credit card form factor that fits in a standard wallet. CC EAL5+. Bluetooth connectivity. The convenience of card form factor comes with the trade-off of Bluetooth as the communication channel. No air-gap. Well suited for daily spending wallets with small balances.

The only hardware wallet with a built-in fingerprint sensor. CC EAL5+. Bluetooth and USB. The fingerprint template stays inside the secure element and never transmits. Solid for users who want biometric authorization and are comfortable with Bluetooth connectivity.

Bluetooth and USB. CC EAL5+. Primarily adopted in Asian markets. Mobile-first design. Strong for users already in the Asian crypto ecosystem. Limited DeFi integration compared to Ledger or Trezor.

KeepKey was originally developed independently, then acquired by ShapeShift. When ShapeShift went fully decentralized in 2021 and eliminated its corporate structure, KeepKey's development support became unclear. As of 2026, verify current firmware update status and community support before purchasing. A hardware wallet with uncertain maintenance is a security liability regardless of the hardware quality.

Bluetooth and USB. CC EAL5+. Touchscreen. Cross-platform support. No affiliate program available. Reasonable mid-tier option for users wanting Bluetooth convenience without the Ledger price premium.
