Tangem Tangem Wallet (2 carte)
A plan byTangem
Tangem is a card-shaped NFC hardware wallet: no cables, battery or screen — you tap your smartphone against the card to sign transactions via the Tangem app. It is built around a Common Criteria EAL6+ certified secure element and supports over 90 networks and 14,000+ assets (multichain). Its distinctive feature is the 'seedless' option: keys can be generated by the hardware TRNG and stay forever inside the chip, with no seed phrase to write down (a BIP-39 12/24-word seed remains available as an option). The entry set is the 2-card pack (≈€50, $54.90); a 3-card pack (≈€64, $69.90) is also offered for redundancy. Companion app: Tangem.

Verdict
Score 4.1/5, very strong profile. In its favour: eAL6+ certified secure element; seedless option (no seed phrase to safeguard); battery/cable-free NFC card form factor; multichain (90+ networks, 14,000+ assets); low entry price (≈€50). The trade-off to weigh: the secure element firmware is closed-source (only the apps are open-source); the seedless model ties recovery to physical redundancy of the cards; requires an NFC smartphone for every operation; no on-device screen for independent verification.
On the Sovereignty lens the score is 4.2/5 (very strong): the strength is privacy & anonymity (5.0/5), while trustless / auditability (2.5/5) is the weak link.

FAQ
How much does Tangem cost?
The entry set is the 2-card pack, about €50 ($54.90). The 3-card pack, offering more redundancy if a card is lost, costs about €64 ($69.90).
Does Tangem work without a seed phrase?
Yes: the recommended option generates keys via the hardware TRNG and keeps them forever inside the secure element, with no seed phrase to write down. Alternatively you can generate a BIP-39 12/24-word seed. Redundancy is provided by buying multiple cards sharing the same key.
Is Tangem open-source?
Only partly: the mobile apps are open-source, but the secure element firmware is closed-source. That's why we classify it as partially open-source.
