Over a three-month period, contributed to LedgerHQ/app-ethereum by delivering nine new features focused on EIP-7702 authorization and advanced Ethereum transaction support. Developed end-to-end authorization flows, device-specific smart contract whitelisting, and robust UI enhancements, using C, Python, and JavaScript across embedded and backend systems. Improved security and interoperability by implementing TLV/DER-based signing authorization encoding and activation flag gating, while expanding test coverage for multiple hardware devices. The work included removing legacy device dependencies, refining user-facing authorization messaging, and strengthening CI/build automation. These efforts provided a stable, extensible foundation for secure Ethereum smart contract interactions and streamlined developer onboarding.
