How can the authenticity of the Tangem firmware be verified?

Tangem uses a “security through obscurity” approach. Disclosing the source code will make its hardware wallets vulnerable. To prove that the Tangem firmware does not have backdoors or bugs that could lead to loss of funds, we went through two independent audits of the Tangem firmware.

The first audit was conducted in 2018 by the Swiss company Kudelski Security and the second in 2023 by the international security laboratory Riscure. 

Both audits confirmed the integrity of our system, establishing that the private key was generated using a hardware random number generator and that there were no backdoors or bugs that could lead to the loss of funds.

You can read the detailed reports of both audits. Kudelski Security's audit results are available here, and information about the second audit conducted by Riscure can be found here.
