Gate News message, March 31, Jan Setina, Trezor’s firmware product director, said at EthCC[9] that his team is moving the firmware architecture from a monolithic design to a modular application platform. The initiative is intended to address structural bottlenecks from the past, including slow integration caused by the internal teams needing to review all code, as well as limitations in hardware storage. Developers can now use its SDK and emulator to develop, publish, and maintain applications on their own. This round of firmware modularity supports applications with on-demand dynamic loading, and each application runs in its own isolated sandbox, ensuring that a vulnerability in a single application will not affect other applications. It improves the flexibility of feature expansion while maintaining security.
