Sui Blockchain Unleashes Full Beta gRPC Support—Turbocharging Data Access for DeFi & dApps

Sui just flipped the switch on full beta gRPC support—and the blockchain’s data pipes just got a lot wider. Here’s why it matters.

No More API Bottlenecks

Real-time queries, seamless dApp integrations, and institutional-grade data streams are now live. Sui’s move slashes latency for developers building everything from high-frequency DeFi to NFT marketplaces.

The gRPC Edge

Binary protocol efficiency meets Web3. Faster syncs, leaner payloads, and bidirectional streaming put Sui ahead of chains still wrestling with REST endpoints. TradFi middleware? Consider it outflanked.

A Cynic’s Footnote

Wall Street spends millions on ‘low-latency infrastructure.’ Sui just open-sourced it—with zero licensing fees. The irony? Priceless.

Sui Blockchain has announced the full beta launch of gRPC support on its Full Nodes, marking a significant advancement in its data infrastructure capabilities. This development aims to provide a faster, more reliable, and developer-friendly way to access blockchain data, according to sui Foundation.

gRPC: A New Era for Blockchain Data

gRPC, a high-performance communication protocol designed for modern distributed systems, is set to become the backbone of Sui's long-term data serving strategy. It offers several advantages over the traditional JSON-RPC, including strong typing, client generation support across multiple programming languages, and efficient binary serialization through Protobuf.

This beta release introduces a comprehensive suite of services, such as MovePackageService, SignatureVerificationService, and TransactionExecutionService, among others. These services are designed to support a wide range of developer needs, from transaction execution to real-time data streaming.

Benefits and Capabilities

The inclusion of a SubscriptionService within the gRPC framework allows for server-side streaming APIs, enabling developers to subscribe to real-time onchain activities. This feature is particularly beneficial for developers, exchanges, indexers, and RPC providers, offering them real-time data synchronization without the need for constant polling.

gRPC's introduction also signifies the beginning of a gradual phase-out of Sui's JSON-RPC, as gRPC is set to become the canonical API for Full Nodes. This transition promises lower latency, richer semantics, and a more scalable integration path.

Implications for Developers and Infrastructure

With gRPC, developers can build responsive applications powered by real-time data, simulate and execute transactions, and track live user activities more efficiently. Exchanges can benefit from faster transaction execution and verification, while indexers and data providers can maintain high-performance APIs by combining live subscriptions with batch queries.

This strategic shift aligns with Sui's vision of reimagining blockchain data serving and consumption. The roadmap includes a clear separation between raw data and derived data, support for real-time streaming alongside batch APIs, and the development of a next-generation indexer framework.

For developers eager to leverage these advancements, Sui provides comprehensive guides and proto files on GitHub to facilitate the transition to gRPC. This release represents a pivotal step toward establishing a faster, more scalable data LAYER for future Web3 applications.
