Aperture gRPC (Beta)

Ultra-Low Latency Solana Data, Forged in Performance.

In the high-stakes arena of Solana trading and data analytics, standard data streams are a bottleneck. You don't need another generic feed; you need a tactical advantage.

Aperture gRPC by RPC Fast is an optimized gRPC layer designed to protect throughput, manage concurrency, and keep reaction latency predictable. It integrates raw Solana shreds with the high-performance Yellowstone gRPC framework.

Currently in Beta – available on request within the Aperture Plan.

Designed for HFT teams, searchers, and real-time analytics platforms, Aperture delivers blazing-fast block, transaction, and account-level data directly from Solana’s validator pipeline – with consistency, resilience, and seamless developer ergonomics.

Aperture converts the data into Yellowstone gRPC' compatible stream, so you can use "transactions" filter for subscription, and use sub-filters such as account_include where you can specify, let's say, pump.fun programs ids.

Architecture

Aperture solution embraces the best of both architectures, solving both latency and integration pains.

• The raw speed of shreds

• The developer-friendliness + extensibility of Yellowstone gRPC

Our deep integration of the raw Solana shreds ensures you receive data at the network's physical limit – direct from the leader's shreds, not through slower, processed blocks. Along with that, we eliminated the integration complexity, giving you immediate access to shredstream's low-latency benefits without the development overhead.

Note: Aperture doesn’t include the transaction execution layer, hence the data is incomplete, compared to Yellowstone gRPC feed.

Solution Benefits

Unlike generic RPC polling or delayed WebSocket feeds, Aperture taps into native raw shred ingestion and wraps it into a clean, production-ready gRPC interface compatible with the Yellowstone ecosystem.

This solution ensures:

• Sub-millisecond data propagation from Solana validators

• Ordered, loss-resistant block and transaction streams

• Flexible real-time subscriptions (transactions, accounts, slots, blocks, logs)

• Multi-node redundancy ensuring no gaps even under heavy chain load

• Drop-in integration for existing Geyser/Yellowstone-based systems

Built in-house by RPC Fast engineers, Aperture inherits our production-grade networking, observability, failover, and multi-region infrastructure – engineered specifically for high-throughput, latency-sensitive workloads.
