Latency matters a lot especially in high-frequency trading (HFT). Traders compete with each other based on their access to fast market data, by receiving and processing faster market data, they can have an edge in the market.
An efficient way to deliver such real-time data with laser like accuracy is through gRPC streaming. It is a high-performance, real-time communication protocol that enables bidirectional streaming between clients and servers using HTTP/2 and Protocol Buffers (Protobuf) for data serialization.
In this article, we’ll explore the best gRPC streaming providers that provide users access to high-speed trading data.
Bitquery gRPC Streams, also known as Smart gRPC Streams or CoreCast , provide users low-latency, context-aware, topic-wise event delivery from blockchain data.
Why Bitquery gRPC?
Bitquery gRPC streaming has the following features:
- Ultra Low latency : Stream RPCs for real-time delivery
- Strong typing : Protobuf contracts for stable schemas and efficient encoding
- Efficient : Binary protocol that’s faster than JSON-based alternatives
Bitquery exposes multiple topics so users can subscribe only to what they need:
- transactions : Finalized transactions with instructions, logs, and status
- transfers : All token transfers with token context
- dex_trades : DEX trade/swaps across supported protocols
- dex_orders : Order lifecycle updates where applicable
- dex_pools : Pool creation/updates and liquidity changes
- balances : Balance updates for tracked accounts and mints
These are filters required to use Smart gRPC Streams. Users must specify at least one filter per subscription; empty filter sets are rejected. Select exactly what to stream by combining filters. Examples include:
- addresses: senders, receivers, owners, program_ids
- tokens: Mint addresses (e.g., WSOL, USDC) and token standards
- value thresholds: Minimal amounts in native or token units
- markets/pools: By protocol, pool, or market identifiers (for DEX topics)
- Filters are applied server-side to reduce bandwidth and speed up downstream processing.
Bitquery’s gRPC streams provide powerful real-time capabilities for copy trading and monitoring trades at scale across blockchain networks, particularly excelling on Solana with platforms like Pump.fun and LetsBonk.fun.
Copy Trading Capabilities

The Yellowstone Geyser gRPC plugin is part of Solana’s real-time infrastructure that provides users access to ultra-fast on-chain data.
Key features include:
- Streams block, transaction, and account updates directly from Solana nodes.
- Provides sub-second updates, ideal for low-latency trading bots and real-time dashboards.
- It allows developers to build trading systems that respond instantly to liquidity changes, arbitrage opportunities, or MEV signals.
This is a very good gRPC streaming plugin for High-Frequency Trading as it connects directly to validators, providing unmatched data freshness, which is important for trading systems operating on the Solana blockchain.
Shyft extends Solana’s Geyser plugin with a managed API and hosted infrastructure, making it easY for developers to access gRPC data without maintaining nodes.
Key features:
- Provides managed Solana gRPC endpoints.
- Offers advanced filtering options and load balancing for scalability.
- Handles reconnections and data recovery for uninterrupted streams.
It saves users time and infrastructure costs by allowing them to subscribe to high-speed Solana gRPC streams while Shyft handles node maintenance, uptime, and optimization.
QuickNode is a leading blockchain infrastructure provider that also offers Yellowstone gRPC access as a part of its Solana node service.
Key features:
- Ready-to-use gRPC endpoints powered by the Yellowstone plugin.
- Built on QuickNode’s low-latency global infrastructure.
- Offers RPC + gRPC + WebSocket combined for flexibility.
- Integrates well with Solana-based analytics or HFT tools.
- It optimizes data routing, so developers can achieve consistent latency across regions.
In high-frequency trading, speed and precision define success. The faster traders have access and react to market data, the stronger their competitive edge. gRPC streaming stands out as a powerful technology for offering real-time, low-latency communication through efficient binary serialization and bidirectional data flow.
Whether you’re building decentralized trading bots, real-time market monitors, or analytical dashboards, the gRPC streaming providers covered in this article gives you the infrastructure needed to operate with millisecond-level accuracy.
