Is the Tangem Wallet Electra Sea secure?

Yes, the Tangem Wallet Electra Sea uses a Samsung-developed secure element chip with EAL6+ certification, the highest security level available. It has open-source, independently audited firmware, and with over 1.6 million Tangem cards sold there have been zero security breaches.

How does the Tangem Wallet Electra Sea work?

Download the Tangem app on your iOS or Android device, then tap your card to activate it via NFC and you're ready to manage crypto. The embedded chip generates a random private key during activation that never leaves the card and cannot be extracted, so no charging, wires, or seed phrases are needed.

Does Tangem hold or control my cryptocurrency?

No, Tangem AG provides only hardware wallets and non-custodial software, and never holds, custodies, or controls your assets. You keep complete ownership and control, with private keys generated and stored only on your own card.
