During April 2025, Xixishidibei focused on improving code clarity and maintainability across multiple repositories, including kaiachain/kaia, filecoin-project/lotus, and elys-network/elys. They addressed documentation inconsistencies, refined test suite naming, and performed non-functional refactors using Go and GraphQL. In lotus, they refactored the TipSet.Equals method to leverage slices.Equal for CID comparison, enhancing readability without altering behavior. Across all projects, Xixishidibei corrected function comments and resolved minor bugs, ensuring documentation accurately reflected code intent. Their work emphasized code documentation, refactoring, and testing, ultimately reducing onboarding friction and making codebases more accessible for future contributors.
