Developed a new sync_states RPC method for the RoochRpcClient within the rooch-network/rooch repository, enabling clients to perform filtered queries on state changes and enhancing state synchronization workflows. Focused on API development and RPC design using Rust, the work improved developer tooling by allowing more flexible and efficient interactions with the Rooch network’s state data. The implementation aligned with repository standards to support future enhancements and maintainability. No major bugs were addressed during this period, with efforts concentrated on feature delivery and client-side improvements, laying the groundwork for ongoing performance and integration advancements across the Rooch ecosystem.
