Designed to match the exact dimensions of a standard credit card, carrying an embedded microchip that establishes a highly secure, encrypted connection with your mobile device via high-frequency NFC.

Zero-Trust Protocol

No middlemen, no servers.

Traditional wallets rely on central servers or vulnerable recovery sheets. Tangem operates on a direct peer-to-peer cryptographic protocol between the card chip and the blockchain network.

The companion application functions solely as a secure visual interface. Your private keys never leave the silicon, ensuring absolute sovereignty over your digital assets.
