Tangem co-founder says Ledger security incident reinforces risks of added device complexity

Tangem co-founder Andrey Lazutkin said a recent security incident involving Ledger has again highlighted a core security-engineering principle: complexity expands the attack surface. In a post on X, Lazutkin argued that each added hardware component or software layer can create new failure points and vulnerabilities. He specifically listed screens, buttons, batteries and firmware as examples of elements that can raise the number of risks that must be identified and mitigated. Lazutkin used the incident to defend Tangem’s minimalist card-based design. He said the product is built only around a secure chip and an antenna, framing that structure as a deliberate security choice rather than a stripped-down feature set. According to his post, the recent Ledger event strengthened his view that this design philosophy is the right one. The comments were cited by ChainCatcher in a brief report published under its technology news category.
