Worked on the matter-labs/zksync-sso-clave-contracts repository, focusing on security hardening, code quality, and maintainability for smart contracts. Addressed audit findings by refining contract architecture, improving signature decoding, and clarifying event names, while standardizing API naming for K1 owner management to enhance clarity. Integrated Slither static analysis into the CI/CD pipeline using GitHub Actions and YAML, enabling automated vulnerability detection on pull requests. Additionally, contributed to developer guidance by adding safety warnings in Solidity interfaces to highlight risks in module unlinking scenarios. The work emphasized backend development, security auditing, and refactoring, resulting in a streamlined, more maintainable codebase.

May 2025 monthly summary for matter-labs/zksync-sso-clave-contracts: Delivered a safety-oriented code comment in the IValidatorManager.sol interface to alert developers to risks associated with unlinking modules and potential uncleared account data if a validator is re-attached after unlinking. While this month did not include runtime feature changes or bug fixes, the enhancement strengthens maintainability and risk visibility in the contract surface.

February 2025 monthly summary for matter-labs/zksync-sso-clave-contracts: Focused on security hardening, API clarity, and code quality driven by OZ audit findings. Delivered architecture refinements, signature decoding improvements, and clearer event names in SsoAccount and OwnerManager; implemented authentication refactor across the system. Standardized K1 owner management API naming to improve maintainability. Cleared deprecated code paths and artifacts to streamline the codebase. Integrated Slither static analysis into the CI/CD pipeline to detect vulnerabilities on PRs. Addressed major OZ audit items (early results and subsequent findings: N-07, N-05, N-08, L-03) with targeted fixes. Impact: reduced attack surface, easier maintenance, faster secure PR reviews, and higher CI quality gates. Technologies: Solidity contract changes, signature decoding, event naming, authentication refactor, Slither CI integration, audit-driven development.
