Over a three-month period, Nicolas Bacca developed and enhanced EIP-7702 authorization features for the LedgerHQ/app-ethereum repository, focusing on secure smart contract workflows and device compatibility. He implemented end-to-end authorization flows, including UI and CLI integration, and expanded support for new Ethereum transaction types using C and Python. His work included TLV/DER-based signing authorization encoding, device-specific feature gating, and comprehensive test infrastructure improvements. By removing legacy device dependencies and introducing activation flags, Nicolas increased stability and interoperability. The depth of his contributions is reflected in robust code quality, expanded test coverage, and improved developer and user experience across supported hardware.
