During April 2025, Wang Yusong developed a new sync_states RPC method for the RoochRpcClient in the rooch-network/rooch repository, focusing on enhancing state synchronization workflows. By implementing filtered state-change queries, Wang enabled clients to interact more flexibly with the Rooch network, improving developer tooling and integration. The work centered on API development and RPC design using Rust, with careful alignment to repository standards to support future enhancements. Although no major bugs were addressed during this period, the feature laid a foundation for faster and more adaptable state synchronization, reflecting a thoughtful approach to both client usability and maintainability.
