Sui GraphQL

November 11th, 2026

Sui GraphQL is now available on Tatum for Mainnet, Testnet and Devnet. Request exactly the fields you need and resolve related data (address → balances → objects → transactions) in a single query, all against one typed, self-documenting schema. Together with Sui gRPC, GraphQL is the supported way to read Sui data now that Sui has deprecated JSON-RPC.

Try Sui GraphQL

Sui GraphQL endpoints

What you get

  • Exact field selection: Return only the fields you need, which keeps payloads small and responses fast.
  • Fewer round trips: Resolve nested data, such as an address with its balances, owned objects and transactions, in one request.
  • Broad coverage: Query objects, transactions, checkpoints, epochs, events, coin metadata, Move packages and SuiNS name records.
  • Write and simulate: Execute signed transactions with the executeTransaction mutation, dry-run them with simulateTransaction, and check signatures with verifySignature.
  • Self-documenting schema: Introspect the schema to discover every query, type and argument, then generate typed clients.
❓

GraphQL or gRPC?

GraphQL endpoints don't support WebSocket subscriptions. For real-time checkpoint streaming, use Sui gRPC and its SubscriptionService.

Migrating from JSON-RPC?

Still calling Sui JSON-RPC methods? The JSON-RPC to GraphQL migration guide maps each sui_ and suix_ method to the GraphQL field that replaces it.
