ERPC Significantly Expands Solana Geyser gRPC Infrastructure in the Frankfurt Region. Scaling to Meet Surging Demand While Further Extending Industry-Leading Low-Latency Streaming

ERPC, operated by ELSOUL LABO B.V. (Headquarters: Amsterdam, the Netherlands; CEO: Fumitake Kawasaki) and Validators DAO, announces that it has completed network improvements and the addition of large-scale nodes for its shared Solana Geyser gRPC endpoint in the Frankfurt (FRA) region in response to rapidly increasing demand.

As a result of this upgrade, the Frankfurt-region Geyser gRPC endpoint has transitioned to an architecture capable of stably handling significantly larger volumes of traffic than before. It is now continuously delivering industry-leading low-latency streaming with strong stability characteristics across both latency and delivery consistency.

The Frankfurt region hosts the highest concentration of Solana validators globally and therefore has structural characteristics that naturally attract demand for real-time data delivery, including Geyser gRPC.

In Solana, block leaders rotate at very short intervals, causing the communication origin point to shift continuously. Under this model, operational performance is influenced less by proximity to a single fixed endpoint and more by the probability of remaining close to clusters of major nodes and validators. This probabilistic proximity directly affects practical metrics such as latency, retransmission rates, and failure rates.

As a result, use cases with diverse load characteristics—including indexers, trading systems, backend processing, and monitoring—have increasingly concentrated on the shared Geyser gRPC endpoint in the Frankfurt region. Recently, this led to a sharp increase in both connection counts and streaming requests.

During the period of rapid demand growth, intermittent block delays were observed at certain times.

ERPC conducted a comprehensive investigation across multiple layers, including Geyser gRPC delivery paths, internal proxy processing, and network control mechanisms. The results confirmed that these observations were not caused by outages or implementation defects. Instead, they were the result of a combination of factors.

The primary causes were a short-term concentration of load on shared resources due to surging Geyser gRPC stream demand in the Frankfurt region, along with the presence of a small number of connections that negatively impacted overall delivery quality.

These effects were localized to the Frankfurt region and did not propagate to other regions or affect ERPC’s global network infrastructure.

The measures implemented by ERPC were not temporary mitigations, but permanent infrastructure reinforcements designed with future demand growth in mind.

First, the network architecture supporting the shared Geyser gRPC endpoint in the Frankfurt region was refreshed, including a review of internal routing and control logic. This reduced path bias and processing variance under high-load conditions.

In parallel, new large-scale nodes were added, significantly expanding Geyser gRPC stream processing capacity. By strengthening the scaling characteristics of the shared endpoint, the system has transitioned to an architecture capable of stably handling higher levels of concurrent connections and data volume than before.

Connections identified during the investigation as problematic have already been fully cleaned up, and the service is currently operating in a comfortable and stable state. In addition, ERPC has implemented operational automation that enables immediate response when similar connections are detected in the future, ensuring rapid recovery should comparable situations arise.

Following the completion of these measures, ERPC has confirmed that the Frankfurt-region shared Geyser gRPC endpoint is stable across both latency and delivery consistency.

The previously observed intermittent block delays have been resolved, and the service is now continuously available under normal conditions, providing industry-leading low-latency Geyser gRPC streaming.

This Frankfurt-region infrastructure reinforcement is positioned as an extension of ERPC’s global Geyser gRPC infrastructure upgrade implemented in December 2025.

Through the refresh of streaming infrastructure across all regions and improvements to ERPC’s Rust-based global proxy, overall Geyser gRPC latency and variance have already been significantly reduced. The current initiative applies the same design philosophy to the Frankfurt region, where demand concentration is the highest.

ERPC consistently adopts a strategy of absorbing demand growth through infrastructure reinforcement, rather than through restriction or degradation of service.

New pricing for ERPC’s Solana infrastructure services, including Geyser gRPC, will take effect in February 2026.

January 2026 represents the final period during which new contracts can be initiated under the current open pricing. For users who begin contracts during this period, or who are already under contract, the same pricing will be maintained for as long as the contract remains valid.

Details of the new pricing are already available on the ERPC official website.

Confirmation of current open pricing, initiation of free trials, contract onboarding, and configuration consultations are all handled via the Validators DAO official Discord.

Individual consultations regarding optimal region configurations, selection between standalone gRPC plans and gRPC Bundle plans, and migration design from existing setups—including the Frankfurt-region shared Geyser gRPC endpoint—are available via the Validators DAO official Discord.
