ERPC announces Solana Stream Bundles: born from real-world demand, with multiple Shredstreams and Geyser gRPC included

ELSOUL LABO B.V. (Headquarters: Amsterdam, the Netherlands; CEO: Fumitake Kawasaki) and Validators DAO, which operate ERPC, announce the new product Stream Bundles. It includes multiple Shredstreams and Geyser gRPC, as well as RPC and SWQoS access, allowing the entire flow from detection to confirmation to be completed under a single contract. Stream Bundles was born from real-world demand and is designed for professionals who need both speed and stability.

Shredstream is delivered over UDP and is the fastest, but it can be unstable, making a single subscription insufficient. In practice, subscribing to multiple Shredstreams and adopting the one that arrives first has proven effective. Adding gRPC for confirmation builds a two-step workflow that shortens the time from detection to confirmation and reduces false positives.

Many top traders and ultra-low-latency trading platforms do not rely on Shredstream or gRPC alone. Because Shredstream can vary in results depending on the moment, sometimes A is fastest, sometimes B, and in some cases a shared endpoint even outpaces a dedicated Shredstream. To address this reality, a way to bundle multiple streams together is needed. Stream Bundles responds directly to this demand.

Stream Bundles includes multiple Shredstreams by default, together with gRPC, RPC, and SWQoS access. This enables the standard operational flow of detecting signals with multiple streams and confirming them with gRPC, all under one plan. With the same account available from development through production, it ensures consistency in deployment and operation.

A dedicated Shredstream supports UDP forwarding and can use both UDP and gRPC simultaneously. This makes it possible to leverage three Shredstreams in practice, maintaining lower latency even during peak times. For shared Shredstreams, ERPC applies a large number of nodes to suppress jitter. By combining shared and dedicated streams, projects can balance both speed and stability.

Shredstream is suited for early signal detection, while gRPC is suited for confirmation. Stream Bundles is designed with this two-step process in mind, shortening the path from detection to confirmation. It reduces false positives and missed signals, while allowing development and production to run under the same environment, making the path from testing to deployment smoother.

We have built zero-distance oriented networking and dedicated infrastructure to eliminate the factors that hinder “speed” and “stability” in real Solana operations. From Shredstream to bare metal for applications in the same network, and Geyser gRPC operations, we optimize the entire stack to minimize latency and reduce variance.

Through the development of Epics DAO, an open-source Solana NFT card game project, we experienced firsthand the difficulty of accessing a high-quality, low-latency Solana environment. We built our own platform, and ERPC and SLV are provided based on that knowledge.

Financial applications are especially mission critical, where latency and errors directly affect user experience. With distributed validators and Web3-specific mechanisms layered together, it is often difficult to grasp the whole picture, and many projects have struggled with delays and instability.

We provide the high-performance foundation that is required, and contribute to better development and user experience across the Solana ecosystem. ERPC and SLV are positioned as part of that effort.
