What is a dedicated Solana RPC node and when should you use one?

Dedicated Solana RPC node decision checklist

Before you commit to a dedicated Solana RPC node, run through this checklist to make sure it is the right fit for your workload.

What is a dedicated Solana RPC node?

A dedicated Solana RPC node is a Solana RPC endpoint that is reserved exclusively for your application or team. Instead of sharing infrastructure with many other projects, you get a node instance that only processes your requests. This gives you full control over the node's configuration, resource allocation, and client version.

In contrast, a shared Solana RPC node is a cluster of nodes that multiple customers use. Shared nodes are cost-effective and easy to start with, but they can suffer from rate limits and performance variability when other users spike.

A dedicated node is not a separate type of Solana node; it is the same validator or RPC node software, but deployed in a single-tenant environment. You can think of it as renting a dedicated server instead of sharing a virtual machine.

How does a dedicated Solana RPC node work?

Solana applications communicate with the blockchain through RPC nodes. When your app sends a JSON-RPC request, it goes to an RPC node, which processes the request and returns the result. A dedicated node runs the same Solana client (e.g., Agave) but is configured to serve only your traffic.

Here is a simple example of a JSON-RPC request to get the latest blockhash:

curl https://api.mainnet-beta.solana.com -X POST -H "Content-Type: application/json" -d '
  {
    "jsonrpc": "2.0",
    "id": 1,
    "method": "getLatestBlockhash",
    "params": []
  }
'

With a dedicated node, you would replace the public endpoint with your own endpoint, such as https://solana-dedicated.example.com. The request format is identical, but the infrastructure behind it is dedicated to you.

Dedicated vs shared Solana RPC nodes: key differences

The main differences between dedicated and shared nodes are performance isolation, customization, and cost.

• Performance isolation: Dedicated nodes give you consistent performance because you do not compete with other tenants for CPU, memory, or network bandwidth. Shared nodes can experience latency spikes during peak usage.
• Customization: Dedicated nodes allow you to install plugins, choose client versions, and tune node parameters. Shared nodes offer a fixed set of features.
• Cost: Dedicated nodes are more expensive, often starting at hundreds of dollars per month, while shared plans can be free or low-cost.
• Operational overhead: With a dedicated node, you are responsible for monitoring, updates, and failover unless you use a managed service. Shared nodes are fully managed by the provider.

When should you use a dedicated Solana RPC node?

Dedicated nodes are not for everyone. They are most valuable when you have specific requirements that shared nodes cannot meet.

High-throughput dApps and DeFi protocols

If your application sends a high volume of RPC requests, a shared node may throttle you or return errors. A dedicated node gives you the headroom to handle spikes without hitting rate limits.

Trading bots and market makers

Trading applications need low latency and reliable transaction submission. A dedicated node can reduce the variability in request processing, but you also need to consider transaction landing. Many trading teams combine a dedicated node with a transaction sending service or Jito to improve landing rates.

Real-time data streaming

Solana's Geyser plugin allows you to stream account updates, transactions, and blocks in real time. This is useful for analytics, monitoring, and indexing. Dedicated nodes are often required to run Geyser plugins because they need custom configuration and high bandwidth.

Custom node configurations

If you need to run a specific Solana client version, enable experimental features, or install custom plugins, a dedicated node is the only way to get that level of control.

When a dedicated node is not the right choice

Dedicated nodes are overkill for many projects. If you are just building a dApp, running a small bot, or doing occasional reads, a shared node is more cost-effective and easier to manage.

Also, a dedicated node does not automatically solve transaction landing issues. Solana's transaction processing is complex, and even with a dedicated node, you may need to use additional services to ensure your transactions land reliably. For most developers, a shared node with a good provider is sufficient.

How to choose a dedicated Solana RPC provider

If you decide that a dedicated node is right for you, the next step is choosing a provider. Here are the key factors to evaluate:

• Node performance: Look for providers that offer high-performance hardware and low-latency network connections. Ask about their infrastructure and where their nodes are located.
• Customization options: Check if you can choose your Solana client version, install plugins, and configure the node to your needs.
• Managed services: Some providers offer fully managed dedicated nodes, where they handle monitoring, updates, and failover. This can save you a lot of operational overhead.
• Pricing: Compare pricing models. Some providers charge a flat monthly fee, while others charge based on usage. Make sure you understand what is included.
• Support: Look for providers with responsive support and clear SLAs. You want to know who to contact if something goes wrong.

OnFinality offers dedicated node infrastructure for Solana and other networks. You can explore dedicated node options and RPC pricing to see if it fits your needs. We also support Solana mainnet and devnet endpoints.

Common pitfalls and how to avoid them

1. Underestimating operational complexity

Running a dedicated node is not set-and-forget. You need to monitor disk space, CPU usage, and network health. If you do not have the team to handle this, consider a managed service.

2. Ignoring transaction landing

A dedicated node does not guarantee that your transactions will land. Solana's transaction forwarding and block production are separate concerns. Use a transaction sending service or Jito if you need reliable landing.

3. Not planning for failover

If your dedicated node goes down, your application loses access to the network. Set up a failover strategy, such as a backup shared node or a multi-node cluster.

4. Overpaying for unused capacity

Dedicated nodes are expensive. If you are not consistently using the capacity, you may be better off with a shared plan. Start with a shared node and scale up only when you see real demand.

How to test a dedicated Solana RPC node

Before committing to a dedicated node, you should test it with your workload. Here is a simple way to benchmark latency:

# Measure the time to get the latest blockhash
curl -w "Time: %{time_total}s\n" -o /dev/null -s https://your-dedicated-endpoint.com -X POST -H "Content-Type: application/json" -d '
  {
    "jsonrpc": "2.0",
    "id": 1,
    "method": "getLatestBlockhash",
    "params": []
  }
'

Run this multiple times and compare the average latency with a shared endpoint. Also test under load to see how the node behaves when you send many requests in parallel.

Key Takeaways

• A dedicated Solana RPC node is a single-tenant endpoint that gives you performance isolation and customization.
• It is best for high-throughput dApps, trading bots, and real-time data streaming.
• Dedicated nodes are more expensive and require more operational effort than shared nodes.
• A dedicated node does not solve transaction landing; you may need additional services.
• Choose a provider that offers the right balance of performance, customization, and management.
• Start with a shared node and scale to dedicated only when you have clear evidence of need.

Frequently Asked Questions

What is the difference between a dedicated and a shared Solana RPC node?

A dedicated node is reserved exclusively for your application, giving you full control and consistent performance. A shared node is used by multiple customers and is more cost-effective but can have rate limits and performance variability.
