Own the first signal on Solana

Shreds. Geyser.
Deterministic delivery.
One unified stack.

Docs

Designed for systems that measure performance in milliseconds

Solana produces blocks every ~400ms. HTTP polling and JSON parsing waste that window. We built a multi-layer streaming stack that surfaces transaction flow closer to propagation and keeps delivery stable under load.

Why RPC Fast Streaming Wins

Shred-Level Visibility

See transactions during propagation, not after block formation. Earlier reaction window for HFT and liquidations.

Validator
Memory Feeds

Yellowstone gRPC directly from Geyser. Structured, high-throughput streams without JSON overhead.

Unified Streaming Stack 

Shreds + gRPC + Aperture delivery combined inside SaaS. No fragmented add-ons.

Transparent Throughput

Defined stream capacity per tier. No surprise throttling during volatility.

One Streaming Stack. Three Execution Layers.

Instead of offering one streaming method as an expensive add-on, we integrate all major approaches:

Shred-Level Data Streaming

See transaction flow during propagation, not after block formation.
Shorter signal distance = higher same-block reaction probability.
Built for desks where 50–100ms changes outcomes.

Pre-block shred visibility

Earlier inclusion window

No premium add-on gate

Yellowstone gRPC

Structured transaction and account streams tuned for execution systems.
Lower overhead than JSON RPC. Stable p95 under burst load.

Ordered transaction feeds

Account + slot streams

Fine-grained filters

Aperture gRPC

Aperture is RPC Fast’s optimized gRPC layer designed to protect throughput, manage concurrency, and keep reaction latency predictable. Built in-house to control filtering, routing, and burst behavior so your feed stays stable when the network gets chaotic.
