ERPC Upgrades Network Architecture Supporting Solana HTTP / WebSocket / gRPC Traffic in Frankfurt

ERPC, operated by ELSOUL LABO B.V. (Headquarters: Amsterdam, the Netherlands; CEO: Fumitake Kawasaki) and Validators DAO, has implemented a large-scale upgrade to the network architecture handling HTTP / WebSocket / gRPC traffic in the Frankfurt (FRA) region.

This upgrade has already been applied to the production environment, and all traffic currently using the Frankfurt region is being processed under the new front-layer network architecture.

The reason usage continues to concentrate in the Frankfurt region on the ERPC platform is that the conditions required for stable and consistent results in real-world Solana operations are structurally easier to satisfy in this region.

Frankfurt is a region where major Solana validators and stake are densely concentrated. This concentration represents more than simple geographic proximity; it provides structural advantages in which observation, follow-up, Shreds reception, and state updates can be completed over shorter and more consistent network paths.

Solana operates under an execution model where leaders rotate at short intervals, and block production, Shreds propagation, voting, and state updates proceed continuously with minimal gaps. In this model, results are determined not by average response speed, but by how well latency variance is suppressed and how reliably follow-up remains intact when external disturbances occur.

Frankfurt benefits from a long history of mature interconnection developed for financial use cases, resulting in a network environment with high route stability and predictability. With fewer segments traversing the public internet and close proximity to major aggregation points, the structure is inherently resistant to incidental jitter affecting outcomes.

As these conditions have accumulated over time, Frankfurt has come to be chosen not as a region that is temporarily fast, but as one where high performance is easier to sustain consistently.

ERPC has continuously monitored traffic paths in the Frankfurt region. Through this observation, it became clear that load was not concentrating on the RPC and gRPC nodes themselves, but rather on the proxy layer positioned in front of them.

All HTTP / WebSocket / gRPC traffic passes through this front-layer proxy. In situations where concurrent connections increase and sustained communications overlap, the processing capacity and behavior of this layer directly affect overall communication stability. If processing becomes congested at the proxy layer, the impact propagates downstream, reducing transaction success rates and follow-up reliability.

Because Frankfurt is the region with the highest demand concentration, this front-layer proxy emerged clearly as the next structural constraint. ERPC recognizes this not as an incidental issue, but as an architectural challenge.

In this upgrade, ERPC fully renewed and expanded the front-layer proxy network in the Frankfurt region. Rather than simply increasing the number of machines, the hardware architecture at the traffic entry point was fundamentally re-evaluated to raise both processing headroom and stability.

The front-layer proxy must sustain uninterrupted processing even under consecutive short-term peaks. To meet this requirement, CPU and memory generations were upgraded to the latest available, resulting in a configuration that remains stable under sustained load.

This upgrade is not intended to marginally improve average response times. Instead, it strengthens the underlying foundation required to maintain stable transaction execution conditions under increased demand.

The upgrade is already active in the production environment. All HTTP / WebSocket / gRPC traffic in the Frankfurt region is currently handled by the new front-layer proxy network architecture.

With improved stability at the entry layer, downstream RPC and gRPC nodes can remain focused on their core processing responsibilities. By suppressing fluctuations at the ingress point, overall communication conditions are less likely to degrade.

As part of this upgrade, migration to a new endpoint is required only for the Geyser gRPC service. There are no changes to HTTP or WebSocket endpoints.

The legacy Geyser gRPC endpoint is scheduled to be removed in approximately two weeks. Users currently relying on the old endpoint are requested to complete migration within this period. Details regarding the new endpoint and migration steps are provided via the official Validators DAO Discord.

The open sale pricing for RPC and gRPC services in January 2026 will end in three days. Contracts initiated within this period will retain the open sale pricing for as long as the contract remains active. Details and conditions are available via the official Validators DAO Discord.
