How our 4 spring integrations are wired into the RPC Fast infrastructure

Every one of the four spring 2026 partnerships directly influences how RPC Fast manages data delivery, routing, and execution under congestion. OrbitFlare, Corvus Labs, Astralane, and bloXroute are reputable alone, but together they make RPC Fast a Solana SaaS and data streaming platform ideal for latency-sensitive teams.

If you want to understand what runs under the hood of RPC Fast, this is a good place to start.

OrbitFlare: Raw shreds from one more top-of-Turbine source

OrbitFlare is an enterprise-grade Solana infrastructure provider running Shredstream-optimized RPC nodes, real-time gRPC, raw UDP shred delivery, and a JITO-enabled validator across 11 global regions. 

Their Shredstream product forwards raw Solana shreds from top-of-turbine validators directly to downstream infrastructure via UDP—before those shreds reach any RPC or gRPC endpoint.

RPC Fast has integrated OrbitFlare as an additional raw shred source in our data pipeline. Their shreds are forwarded directly to our infrastructure via UDP from top-of-turbine validators, giving our users access to some of the earliest on-chain signals available on Solana. Earlier shred visibility means tighter reaction windows for trading bots, MEV searchers, and any strategy where slot-level timing matters.

• Raw UDP shreds from top-of-turbine validators;
• Data delivery before any RPC or gRPC layer;
• Frankfurt geo (other locations may be added later).

Corvus Labs: A high-performance routing path inside Beam

Corvus Labs operates high-performance Solana RPC and gRPC endpoints designed to stay fast under load. Their infrastructure spans five regions—Frankfurt, Amsterdam, London, New York, Tokyo—with JSON-RPC, WebSocket, Yellowstone gRPC, Shredstream, and an aRPC variant offering decoded shreds with an 8ms latency advantage over standard shred delivery.

This partnership adds a direct routing path through Corvus into RPC Fast Beam, our unified transaction sender. Beam handles all submission logic automatically—you do not switch endpoints or rewrite integration code.

• Direct-to-leader delivery with tip support;
• Stake-weighted propagation;
• JSON-RPC, HTTP, and QUIC submission paths;
• No public RPC bottlenecks in the routing chain;
• Frankfurt geo (other locations may be added later).

Astralane: Reliable execution when the network is congested

Astralane builds low-latency middleware for high-frequency Solana operations. Their core product, Iris, is a lightweight TPU client that tracks the Solana leader schedule in real time and sends transactions directly to upcoming leaders using staked connections and SWQoS-aware routing. The result is 0–1 slot P90 execution under normal and congested conditions.

RPC Fast partnered with Astralane to strengthen Beam's execution layer during high-traffic events. When network congestion spikes and standard routing paths degrade, Astralane's direct-to-leader delivery maintains landing rates where other paths would drop transactions.

• TPU-direct submission tracking the live leader schedule;
• Partners' network of staked connections across the Solana validator set;
• Staked connection usage via SWQoS for priority execution;
• Optimized fee and tip structures to reduce overspending;
• Frankfurt geo (other locations may be added later).

Beam sender is free on any RPC Fast plan. You cover only priority fees and provider tips.

bloXroute: Global BDN routing joins the Beam stack

bloXroute operates the Blockchain Distribution Network, a global low-latency transaction propagation layer that routes transactions through a purpose-built private network rather than the public internet. It is one of the most established names in HFT and MEV infrastructure across multiple chains.

With bloXroute inside Beam, RPC Fast users get multi-path transaction execution under a single interface. Beam routes across providers automatically—no manual configuration, no choosing between endpoints.

• Lower latency propagation through bloXroute's global BDN, reducing variance versus public internet paths;
• Better landing rates under load via SWQoS-optimized propagation;
• Multi-path execution across multiple propagation channels for redundancy;
• Real-time data streams—transactions, blocks, and events—for faster execution loops;
• MEV-aware routing with leader-aware, multi-path submission to reduce frontrunning exposure;
• Frankfurt geo (other locations may be added later).

What these integrations mean in practice

Four new partners for RPC Fast mean four additional layers in your routing stack. OrbitFlare and the raw shred pipeline push data arrival earlier. Corvus Labs, Astralane, and bloXroute give Beam more paths to reach leaders faster, with higher reliability under congestion.

More integrations are coming!
