Tangem co-founder Andrey Lazutkin stated that the recent Ledger security incident reinforces the engineering principle that complexity expands the attack surface. He argued that every additional component, including screens, buttons, batteries, and firmware layers, introduces new potential points of failure and vulnerabilities that require mitigation. Lazutkin cited this dynamic to defend Tangem’s minimalist card-based architecture, which relies solely on a secure chip and antenna. He asserted that the Ledger incident validates his judgment that reducing hardware complexity is the correct approach to minimizing security risks in self-custody solutions.
