Solana Stream SDK Adds Geyser gRPC Rust Client – Over 200ms Faster than Node.js

2025.06.22
ELSOUL LABO B.V. (Headquarters: Amsterdam, Netherlands; CEO: Fumitake Kawasaki) and Validators DAO are pleased to announce the addition of the highly anticipated Geyser gRPC Rust client to the Solana Stream SDK. This new Rust client achieves an average latency improvement of over 200ms compared to the Node.js version.

Why is the Geyser gRPC Rust Client Important?

Geyser Rust Client
Speed is a critical requirement when using Solana's real-time data streams. The previously popular Node.js-based client offered ease of implementation but left room for performance improvement.
The newly released Rust client is optimized specifically for developers and applications prioritizing performance. It achieves more than 200ms lower latency on average compared to the Node.js client for Geyser gRPC connections.
In the image above, the left console shows the Rust client, while the right shows the Node.js client. The Rust client clearly demonstrates significantly faster responses, with latency improvements of over 200ms.

Key Features of the Geyser gRPC Rust Client

Solana Stream SDK
  • Over 200ms Faster: Outperforms Node.js, making it ideal for trading and real-time analytics.
  • Ready Out-of-the-Box: No special configurations required; immediate usability.
  • High Stability and Low Latency: Rust’s native performance ensures stable operation even under heavy load.
  • Enhanced Multi-Platform Support: Complements existing TypeScript (NPM) with advanced Rust (Crates.io) development options.

Immediate Access and Setup

The Solana Stream SDK is publicly available via GitHub and Crates.io. Detailed usage instructions and sample code for the Rust client can be found through the links below:

Further Integration with SLV

Going forward, the Solana Stream SDK will integrate even more closely with SLV, allowing developers to set up their development environment quickly through a simple, one-command operation. Continued platform-wide optimizations and expansions of open-source resources will ensure easier and faster access to Solana's high-speed streams for all users.

Geyser gRPC Free Trial and Validators DAO Community

Geyser gRPC
Validators DAO actively seeks feedback from the community. We invite you to share your thoughts and requests through our official Discord.
Additionally, the same official Discord offers a 7-day free trial for ERPC. Use this opportunity to experience the speed of Solana streams firsthand and begin developing high-performance applications. We believe this experience will spark inspiration for your projects.
We will continue advancing and refining open-source tools to enhance the Solana ecosystem and provide you with superior development environments.
Thank you for your continued support.
