Tangem Wallet Pack of 2
Tangem Wallet uses a private key generated and stored entirely on the card, eliminating exposure to online threats. It carries top-tier certification (EAL6+) and has firmware audited by Kudelski Security and Riscure, emphasizing strong, externally verified security. The card supports a wide range of tokens across multiple blockchains and enables DeFi, NFT, and DeEx activities without wires, Bluetooth, or computers. To transact, users simply tap the card to their mobile device and use the Tangem app for buying, selling, and interacting with dApps via WalletConnect.
ELLIPAL X Card
The ELLIPAL X-Card is a true air-gapped wallet that generates and stores the seed phrase within the device, never exposing it to the outside world. It carries a CC EAL6+ certified secure element and supports one-tap crypto transactions through the Ellipal app, including buying, selling, staking, swapping, and dApp access via NFC taps. Backup options are flexible: seed phrases can be stored across multiple X-Cards or imported from other BIP39-standard wallets. The card-to-device workflow ensures end-to-end cold storage protection while still enabling convenient interaction with digital assets.
Tangem Wallet Pack of 3
This larger Tangem pack follows the same secure by-design model: the private key never leaves the card, and no wires or batteries are required. The pack expands token coverage and use across wallets and DeFi platforms, with the same NFC tap setup to access the Tangem app for transfers, purchases, and dApps. The emphasis remains on hot-wallet convenience with cold-storage security, so long-term asset protection is the primary goal.
ELLIPAL Titan 2.0
The Titan 2.0 uses an air-gapped, fully internet-isolated design and a CC EAL5+ secure element to maximize security. It is a fully metal, anti-tamper device with a 4-inch touchscreen for account setup and management, supporting up to 10 accounts and quick microSD-assisted updates. Transactions rely on QR codes, ensuring no online exposure during signing. The Titan 2.0’s emphasis is robust physical and cryptographic security for long-term storage of thousands of tokens and NFTs.
Ellipal X Card Pack of 3
ELLIPAL X Card packs extend the air-gapped security approach across multiple devices, allowing seed phrase backup and secure storage across several cards. The X-Card design supports one-tap crypto transactions via NFC and maintains strong security through CC EAL6+ trusted components. If a seed phrase is needed from another wallet, X-Card models can import it, provided the seed follows the BIP39 standard, enabling flexible, multi-device recovery.
Trezor Safe 3
Trezor Safe 3 combines NDA-free security with a Secure Element (EAL 6+) and a clear OLED screen for on-device confirmations. It supports thousands of coins and tokens, providing a robust interface for managing digital assets in a single wallet. The Safe 3 is designed for users who value transparent security and simple, on-device verification when sending or signing transactions, while maintaining broad compatibility with major networks.
Buying Guide: Key Considerations For Card-Based Crypto Wallets
- Security architecture: Look for air-gapped designs, secure elements (EAL ratings), and independent seed storage. The higher the certification (EAL6+ vs EAL5+), the stronger the hardware-backed protection against extraction and tampering.
- Seed phrase handling: Decide whether you prefer seed phrases stored on-device (air-gapped) or managed via multiple backup cards. Seed phrase storage should minimize exposure and support straightforward recovery without compromising security.
- Connectivity and interaction: Card wallets range from NFC-based tap interactions to QR-code signing. Consider how you plan to interact with DeFi platforms, exchanges, or NFT ecosystems and whether you require Google/Apple Pay or card-to-device transactions.
- Token support and scope: Check the number of supported tokens and blockchains, as well as compatibility with DeFi, NFT marketplaces, and WalletConnect integrations. If you hold diversified assets, broader coverage may be advantageous.
- Physical build and durability: Metal bodies, anti-tamper features, and resistance to physical damage matter for long-term storage, particularly for high-value holdings. Consider models with a robust chassis and minimal exposed ports.
- Recovery and compatibility: Some wallets offer multi-card backup, direct imports from other wallets, or straightforward recovery via seed phrases. Ensure recovery methods align with your risk tolerance and backup strategy.
- Ease of use vs. security trade-offs: Some options emphasize seamless daily use with occasional access to hot wallets, while others prioritize strict offline storage with less frequent transactions. Balance convenience with security needs.
- Customer support and ecosystem: A strong support channel and ongoing firmware updates improve long-term reliability. Compatibility with widely used apps and wallets can influence your experience during transfers and staking.
Choosing the right card-based crypto wallet depends on your security priorities, asset mix, and transaction frequency. The options listed span both ultra-secure air-gapped designs and highly versatile, user-friendly cards, offering a spectrum of protection levels and usability to help you safeguard your digital assets.
