Tangem
Tap-to-Sign Hardware Security
Tangem is a unique hardware wallet in the form of a credit card. It uses NFC technology to sign transactions through your smartphone, combining the security of hardware wallets with the convenience of mobile apps. The cards are water-resistant, durable, and have a 25-year lifespan.
XRPL compatibility
Tangem supports XRP natively in the Tangem app and stores your XRP address and balance directly on the card. Sending and receiving XRP is straightforward: pick the asset, enter the amount, and tap the card to your phone to sign. Trustlines and XRPL DEX trading are not exposed in the Tangem app, so power-users typically pair the card with Xaman for advanced XRPL features.
Security model
Each Tangem card contains an EAL6+ certified secure element that generates and stores private keys on-device. There is no seed phrase by default — instead you buy a 2- or 3-card set, and any card in the set can recover the wallet. Transactions are signed inside the chip after an NFC tap, so keys never touch your phone or the internet.
User experience
Setup is the fastest in the hardware-wallet space: scan a card, set a passcode, and you're done in under three minutes. The card-style form factor is waterproof, dust-proof, and survives being carried in a wallet. The trade-off is that signing requires your phone — there is no standalone screen on the card to confirm transaction details, so you rely on the Tangem app's UI.
Security trade-offs
Going seedless removes the single biggest cause of self-custody losses (lost or stolen recovery phrases) but it also means your backup strategy is physical: you must keep at least one extra card in a separate, safe location. The lack of an on-device screen also means you should treat the Tangem app on a clean, trusted phone as part of your security model.
Who it's best for
Tangem is the best pick for XRP holders who want true cold storage without managing a 24-word seed, and who are comfortable making your phone part of the security chain. If you want a screen-equipped device or full XRPL DEX/AMM workflows in the same app, Ledger Nano X paired with Xaman is the better blueprint.

In-Depth Review
Overview and First Impressions
Tangem has done something genuinely novel in the hardware wallet space: it took the security of cold storage and compressed it into a device the size and shape of a credit card. There is no screen, no battery, no USB port, and no Bluetooth radio. Instead, the Tangem card communicates with your smartphone via NFC — you simply tap the card against your phone to sign transactions. The result is a hardware wallet that you can carry in your physical wallet alongside your bank cards, making it one of the most portable secure storage solutions available.
The card itself is built to last. Tangem rates its chip lifespan at 25 years and the card body is IP68 water-resistant, dust-proof, and resistant to extreme temperatures. Each order comes with either two or three cards that share the same wallet, providing built-in redundancy. If you lose one card, the others still grant full access to your funds — and if someone finds your lost card, they cannot use it without your phone and PIN.
User Experience and Daily Use
Setting up Tangem is refreshingly simple. Download the Tangem app on iOS or Android, tap your card to your phone, set a PIN, and you are ready to go. There is no seed phrase to write down — the private key is generated on the card's secure element chip and never leaves the hardware. This is a deliberate design choice that eliminates the most common attack vector in crypto: compromised seed phrase backups. Your backup is the second (or third) physical card in your set.
Day-to-day use revolves around the companion app. The interface is clean and supports XRP along with thousands of other cryptocurrencies. To send a transaction, you enter the details in the app and then tap your Tangem card to physically authorize the signing. The NFC tap takes about one second and provides a satisfying confirmation that your keys are being used in a secure, air-gapped manner. For XRP holders specifically, Tangem supports native XRPL transactions including trustlines and token management, though it does not provide access to the XRPL DEX or xApps the way Xaman does.
Security Deep Dive
The security model of Tangem is fundamentally different from traditional hardware wallets. Because there is no screen on the card, transaction details are displayed on your phone — which means you are trusting the Tangem app to accurately show what you are signing. Tangem mitigates this by keeping the app open-source and undergoing regular third-party security audits. The card's chip is a Samsung S3D350A secure element, the same class of chip used in banking cards and passports, certified to EAL6+ on the Common Criteria scale.
The lack of a seed phrase is both Tangem's greatest strength and a point of concern for some users. If you lose all your cards, there is no way to recover your funds — period. This makes the multi-card backup system essential, and we strongly recommend storing at least one backup card in a separate physical location. For users who are disciplined about physical security but struggle with seed phrase management, Tangem's approach is arguably more secure in practice than a seed phrase written on paper.
Who Should Use Tangem
Tangem is ideal for users who want hardware wallet security without the bulk and complexity of a traditional device. It is particularly well-suited for people who travel frequently, want a backup cold storage solution alongside a software wallet, or are buying their first hardware wallet and want something that does not feel intimidating. The price point — starting at $54.90 for a two-card set — is also significantly lower than competing hardware wallets, making it an accessible entry point into self-custody.
Where Tangem falls short is for power users who want a complete XRPL ecosystem experience. It does not support dApp browsing, NFT management, or AMM participation the way Xaman does. For many users, the best setup is actually a combination of both: Xaman for daily XRPL interaction and Tangem for long-term secure storage of larger holdings.
