Sui has activated GraphQL subscriptions on its mainnet, allowing developers to stream checkpoints, transaction blocks and events through persistent WebSocket connections. The service supports GraphQL-based filtering, automatic reconnection and cursor-based backfilling, enabling applications to recover missed data before resuming live updates. The rollout completes Sui's migration from JSON-RPC: GraphQL RPC entered beta in 2025, became generally available in early 2026, and JSON-RPC was fully phased out on Foundation nodes in late July 2026. The feature is aimed at real-time applications, including agentic finance and decentralized finance products. The report also listed Sui at $0 with no significant trading volume during the previous 24 hours, while noting that developers and traders will monitor adoption and engagement after the launch.
