Implement comprehensive event indexing and analytics dashboard

[Yusufolosun]

Problem Statement

Currently, users have limited visibility into historical payment flows and distribution patterns within SplitStream contracts. While events are emitted on-chain, there's no easy way to query, aggregate, or visualize this data for operational insights or compliance reporting.

Proposed Solution
Develop a complete event indexing system and analytics dashboard that provides:

Backend Infrastructure

• Event listener service that monitors all SplitStream contract instances
• Database schema for storing historical payment data
• GraphQL/REST API for querying indexed data
• Real-time WebSocket updates for live monitoring

Analytics Dashboard Features

• Total volume processed per contract
• Payment distribution breakdown by payee
• Timeline visualization of payments received vs. released
• Average time-to-withdrawal metrics
• Gas cost analytics per operation
• Export functionality (CSV, JSON) for accounting purposes

Technical Requirements

• Support for multiple contract instances
• Historical data backfill from contract deployment
• Efficient querying with pagination and filtering
• Mobile-responsive dashboard UI
• Authentication for private contract monitoring

Success Criteria

• Index 100% of PaymentReceived and PaymentReleased events
• Query response time < 500ms for typical date ranges
• Dashboard loads and displays data within 2 seconds
• Support concurrent monitoring of 10+ contracts
• Zero data loss during indexer restarts

Implementation Tasks

• Design database schema for event storage
• Build event indexing service (Node.js/Python)
• Create API layer for data access
• Develop frontend dashboard (React/Next.js)
• Add authentication and access control
• Write integration tests for indexer
• Deploy to production environment
• Create user documentation
