Here's an overview of the Tangem Wallet's security features:
Anti-counterfeit Technology: The Tangem app verifies the authenticity of both the chip and the firmware. Full protection against counterfeiting and cloning of cards. The app confirms the cards’ authenticity when you tap them against your phone.
EAL6+ level: The Tangem chip has the highest chip security standard available. It is protected from invasive and non-invasive attacks. Private keys are generated inside the chip during wallet activation. Nobody has access to your private key, and it cannot be revealed under any circumstances.
Audited firmware: The Tangem firmware has two independent audits: one in 2018 by the Swiss company Kudelski Security and another in 2023 by Riscure, an international security lab. Both audits confirmed that the firmware has no backdoors or vulnerabilities, is not updatable, and contains no hidden algorithms.
Open-source app: The Tangem app is open-source on GitHub and has been verified by the community. There are no backdoors, and anyone can recreate the app if necessary.
Autonomy: Tangem doesn't collect personal data or run servers to conduct transactions on the blockchain. It's just your wallet, the app, and the blockchain.
Smart backup system. The chip in the card generates a random private key that never gets exposed. The cards establish a secure connection with each other and transfer your encrypted private keys. The keys are stored on three cards with no other copies in space and time.
Access code protection: Tangem cards are protected against unauthorized access and brute-force attacks by the user's access code or biometric authentication.
