Hi @Abd-Standard, I'd like to work on this issue.

I've reviewed the requirements and understand that the goal is to provide maintainers with clear visibility into the indexing pipeline, including synchronization progress and processing latency.

My approach would be to:

• Build a dashboard view that surfaces key health metrics such as indexed block height, latest processed block, synchronization status, and processing delays.
• Present metrics in a clear and responsive layout using reusable dashboard components.
• Include loading, empty, and error states to ensure the interface remains informative under all conditions.
• Add visual indicators for lag or unhealthy states so maintainers can quickly identify issues.
• Ensure the dashboard updates in near real time and remains performant as metrics change.
• Keep the implementation scoped and aligned with the existing project structure and UI patterns.

I'll validate the displayed metrics carefully and ensure all acceptance criteria are satisfied before submitting a PR.
