Overview

​

What is Solana RPC?

RPC (Remote Procedure Call) nodes are the gateway to interacting with the Solana blockchain. They allow applications to:

• Read blockchain data like account balances and transaction history
• Submit new transactions to the network
• Subscribe to events and updates
• Query current network status and performance

Without RPC nodes, applications couldn’t communicate with the Solana blockchain. These nodes maintain a full copy of the blockchain and expose standardized APIs that developers can use to build applications.

Types of Helius RPC Nodes

Helius offers two types of RPC node solutions to meet different needs:

​

RPC Nodes

RPC nodes are our standard offering that provides high-performance, reliable access to the Solana blockchain at an affordable price point.

Key benefits:

• Cost-effective solution for most projects
• No setup or maintenance required
• Globally distributed for low-latency access
• Automatic routing to the nearest node
• Flexible pay-as-you-go pricing

​

Dedicated Nodes

Dedicated nodes provide a private, exclusive environment optimized for gRPC streaming applications. These nodes are ideal for real-time data streaming, trading applications, and analytics that require ultra-low latency blockchain data feeds.

Key benefits:

• Primary use case: High-performance gRPC streaming via Yellowstone Geyser
• Exclusive access with no resource competition
• Ultra-low latency for real-time data feeds
• Enhanced security and isolation
• Predictable billing regardless of usage patterns

Important: Dedicated nodes should be combined with a shared plan for full functionality, as they do not support archival data. While sendTransaction and getProgramAccounts are supported, they are not optimized - sendTransaction will cause most transactions to not land, and heavy getProgramAccounts usage can impact node performance or cause node failure.
