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

Quick recommendation: Is a dedicated Solana node right for you?

Before diving into the details, here's a quick way to decide if a dedicated Solana node is the right investment for your project. Answer these three questions:

1. Do you need consistent, low-latency access to Solana data? If your application depends on real-time price feeds, order book updates, or frequent account polling, a dedicated node can provide more predictable performance than a shared endpoint.
2. Are you hitting rate limits or experiencing throttling on shared RPCs? If your traffic is bursty or you're running high-frequency trading bots, a dedicated node removes the contention caused by other users on the same infrastructure.
3. Do you need custom configuration or plugins? Dedicated nodes often allow you to enable features like Geyser plugins for streaming data, or to tune the node client to match your workload.

If you answered yes to any of these, a dedicated Solana node is worth considering. If your application is in early development or has modest traffic, a shared RPC endpoint may be sufficient and more cost-effective. You can always start with a shared endpoint and migrate to a dedicated node as your usage grows.

For a managed solution, OnFinality offers dedicated nodes on Solana, with the flexibility to scale as your project evolves. You can also compare RPC pricing and see the full list of supported networks.

What is a Solana dedicated node?

A Solana dedicated node is a single-tenant RPC endpoint that runs a Solana node exclusively for your application. Unlike shared RPC endpoints, where multiple projects use the same node and compete for resources, a dedicated node gives you a private, isolated environment. This means you don't have to worry about other users' traffic impacting your performance, and you have more control over the node's configuration.

Dedicated nodes are often used for:

• High-frequency trading: Applications that need to submit transactions and read state with minimal latency.
• Data analytics: Platforms that process large volumes of on-chain data and require consistent throughput.
• Real-time monitoring: Services that track account balances, token transfers, or other events in real time.
• Production dApps: Applications with a large user base that need reliable, predictable RPC access.

How does a Solana dedicated node differ from shared and self-hosted nodes?

To understand the value of a dedicated node, it helps to compare it with the other two main options: shared RPC nodes and self-hosted nodes.

Shared RPC nodes

Shared RPC nodes are the most common way to access Solana. Providers like OnFinality offer public and shared endpoints that are easy to use and require no infrastructure management. However, because these endpoints are shared among many users, they can experience rate limiting and performance degradation during peak usage.

Self-hosted nodes

Running your own Solana node gives you full control over the hardware, software, and configuration. This is the most flexible option, but it comes with significant operational overhead. You need to manage the server, keep the node synchronized, handle upgrades, and ensure high availability. For most teams, this is not a good use of engineering time.

Dedicated nodes (managed)

A dedicated node from a provider like OnFinality sits between shared and self-hosted. You get a private node that is managed for you, so you don't have to worry about the underlying infrastructure. This gives you the performance and control of a self-hosted node without the operational burden.

Here's a comparison table to summarize the key differences:

When should you choose a dedicated Solana node?

A dedicated node is not the right choice for every project. Here are some scenarios where it makes sense:

• You need low latency: If your application is latency-sensitive, such as a trading bot that needs to react to price changes in milliseconds, a dedicated node can reduce the time it takes to get a response.
• You have high throughput requirements: If you're making thousands of requests per second, a shared endpoint will likely throttle you. A dedicated node can handle this volume without issues.
• You need to run custom plugins: Some use cases, like streaming data via Geyser, require a dedicated node because shared endpoints don't support custom plugins.
• You want predictable performance: With a dedicated node, you don't have to worry about other users' traffic affecting your application. This is important for production applications that need to meet SLAs.

How to evaluate a Solana dedicated node provider

If you've decided that a dedicated node is right for you, the next step is choosing a provider. Here are the key factors to consider:

• Performance: Look for providers that offer low-latency connections to the Solana network. You can test this by making requests from your own infrastructure and measuring the response time.
• Reliability: Check the provider's uptime track record and whether they offer any SLAs. A good provider should have redundant infrastructure and a plan for handling node failures.
• Support: Make sure the provider offers responsive support, especially if you're running a production application. You'll want to be able to get help quickly if something goes wrong.
• Pricing: Compare pricing models. Some providers charge a flat monthly fee, while others charge based on usage. Make sure you understand what's included in the price, such as bandwidth and request volume.
• Features: Consider what features you need, such as WebSocket support, archive data, or Geyser plugins. Not all providers offer the same set of features.

Setting up a Solana dedicated node with OnFinality

OnFinality makes it easy to get a dedicated Solana node. You can provision one through the OnFinality dashboard in just a few minutes. Here's a general overview of the process:

1. Create an account on OnFinality and navigate to the dedicated node section.
2. Select Solana as the network and choose your desired configuration, such as the node type and region.
3. Review the pricing and confirm your order. OnFinality offers flexible plans to suit different workloads.
4. Once your node is ready, you'll receive an RPC endpoint that you can use in your application.

For example, you might get an endpoint like https://solana.api.onfinality.io/public for shared access, but your dedicated node will have a unique URL that is private to you.

Connecting to your dedicated node

Once you have your dedicated node endpoint, you can connect to it using any Solana RPC client. Here's a simple example using @solana/web3.js:

import { Connection, clusterApiUrl } from '@solana/web3.js';

// Replace with your dedicated node URL
const endpoint = 'https://solana.api.onfinality.io/public';
const connection = new Connection(endpoint, 'confirmed');

async function getBalance(publicKey) {
  const balance = await connection.getBalance(publicKey);
  console.log(`Balance: ${balance} lamports`);
}

You can also use WebSocket for real-time subscriptions. OnFinality provides a WebSocket endpoint for Solana, which you can use for things like account updates and transaction notifications.

Common pitfalls and how to avoid them

Even with a dedicated node, there are some common mistakes that developers make. Here are a few to watch out for:

• Not using WebSocket for real-time data: If you're polling the RPC for updates, you're wasting resources. Use WebSocket subscriptions to get push notifications instead.
• Ignoring rate limits on other APIs: Even with a dedicated node, you may still be subject to rate limits on other APIs you use, such as Jupiter or Helius. Make sure you understand the limits of all the services you depend on.
• Not monitoring your node: Even though a dedicated node is managed, you should still monitor its performance to ensure it's meeting your needs. Set up alerts for high latency or errors.
• Choosing the wrong node type: Solana nodes come in different flavors, such as validator nodes and RPC nodes. Make sure you choose the right type for your use case.

Key Takeaways

• A Solana dedicated node provides exclusive access to a Solana node, offering better performance and control than shared RPC endpoints.
• It's ideal for high-throughput, latency-sensitive applications like trading bots and data analytics.
• When choosing a provider, evaluate performance, reliability, support, pricing, and features.
• OnFinality offers managed dedicated nodes for Solana, simplifying the process of getting your own node.
• Start with a shared endpoint if you're just getting started, and migrate to a dedicated node as your needs grow.
