Leo delivered a focused configuration update to the lifinance/contracts repository, enhancing security by extending the WHITELIST in Config.sol to include the Diamond proxy and VM entrypoint. This change enabled more controlled cross-contract interactions, reducing the attack surface and supporting future integrations with minimal overhead. Working primarily with Solidity and leveraging skills in configuration management and smart contract development, Leo implemented the update through a targeted commit, ensuring that only designated contracts could interact with sensitive components. The work demonstrated a clear understanding of secure contract architecture and provided a maintainable path for future governance and integration within the codebase.
