Sui gRPC

Sui gRPC is available on Tatum for teams that want a faster, more structured, and type-safe way to access chain data than legacy JSON-RPC over HTTP. With Sui gRPC, you work with strongly typed Protocol Buffers request and response messages across ledger, state, Move package, name service, signature verification, and transaction execution methods. That makes Sui a strong fit for backends, indexers, explorers, wallets, and internal services that value predictable schemas, generated client code, and efficient binary transport.

What you get

• Typed APIs: Sui gRPC exposes strongly typed Protobuf request and response messages across services such as LedgerService, MovePackageService, NameService, SignatureVerificationService, State methods, and TransactionExecutionService.
• Smaller payloads: gRPC uses Protocol Buffers, which are generally more compact and structured than JSON.
• Cleaner integrations: Generated gRPC clients reduce manual request building and response parsing across supported languages.
• Good fit for backend workloads: Ideal for objects, transactions, checkpoints, balances, Move package metadata, SuiNS queries, signature verification, and transaction execution or simulation.
• Live checkpoint streaming: Sui gRPC also supports real-time checkpoint subscription streaming through SubscriptionService.
