Summary

Implement a subgraph (The Graph) for indexing on-chain events, enabling efficient historical queries for trade history, positions, and market lifecycle.

Tasks

• Design subgraph schema: Market, Outcome, Position, Trade entities
• Implement AssemblyScript event handlers (ConditionPreparation, PositionSplit, Transfer, etc.)
• Deploy to The Graph hosted service or self-hosted graph-node
• Implement GraphQL queries for frontend (history, volume, charts, leaderboard)
• Add subgraph health monitoring
• Create migration plan from SyncService to subgraph-backed queries

Notes

• Complements but doesn't fully replace current SyncService
• Real-time data still needs WebSocket; subgraph is for historical queries
• Consider Goldsky for production reliability
