Question 1

How Do You Evaluate Geo-Distributed Solana RPC Services for Production?

Accepted Answer

Geo-distributed Solana RPC matters because Solana's slot times and confirmation windows are short, so the physical distance between your users, your backend, and the validator set directly shapes how fast transactions land. A single-region endpoint can look fine in a dashboard while users on other continents absorb the latency.

This article explains how to evaluate geo-distributed Solana RPC services: what to measure, how to test failover across regions, and where shared endpoints stop being enough. It also covers when a dedicated node or a managed RPC API such as OnFinality is the better fit for your workload.

Question 2

Free Solana RPC nodes: when are they enough for your app?

Accepted Answer

Free Solana RPC nodes are public or shared endpoints that let you read chain data and submit transactions without a paid plan. They are useful for prototypes, local development, wallet setup, and low-volume scripts, but they usually come with shared capacity, request limits, and no operational guarantees. This page explains how to connect to a free Solana endpoint, what breaks first under load, and when to move to a managed or dedicated node. OnFinality offers a public Solana endpoint plus managed RPC API and dedicated node options when your workload outgrows free access.

Question 3

Solana Validator Setup: What to Prepare Before You Stake SOL

Accepted Answer

Running a Solana validator means operating a voting node that participates in consensus, which requires careful hardware planning, key management, and a reliable RPC connection for monitoring and operations. This guide walks through the practical preparation steps, the tradeoffs between running your own validator versus delegating, and how to keep your node observable once it is live.

You will find a decision-oriented checklist, hardware and network requirements, key generation and vote account setup, monitoring signals, and common failure modes. Where a managed RPC or dedicated node helps, we point to OnFinality's Solana infrastructure as an option for the RPC and observability side of your setup.

Question 4

PublicNode Solana RPC Endpoint: How to Connect and What to Expect

Accepted Answer

PublicNode offers free Solana RPC endpoints for developers who want to test applications without committing to paid infrastructure. This article explains how to find and use the PublicNode Solana RPC endpoint, what rate limits and reliability to expect, and when to move to a managed or dedicated RPC provider like OnFinality for production workloads.

Question 5

How do I use the Solana explorer API to inspect transactions and accounts?

Accepted Answer

The Solana explorer API is the JSON-RPC interface that powers block explorers and lets developers query transactions, accounts, and blocks. This article explains how to use it for debugging and analytics, and how to choose a reliable RPC provider for production workloads.

Question 6

How to Choose Solana RPC Providers for NFT Data APIs

Accepted Answer

Choosing the right Solana RPC provider for NFT data APIs means balancing read-heavy workloads, WebSocket subscriptions, and the need for reliable getAsset and getAssets responses. This guide explains what to evaluate—from rate limits and archive data to dedicated nodes—so you can match infrastructure to your marketplace, wallet, or analytics use case.

Question 7

Solana Endpoint Issues: How to Diagnose and Fix RPC Failures

Accepted Answer

Solana endpoint issues can stall dApps and trading bots. This article walks through common failure modes—timeouts, 429s, WebSocket drops, and slot lag—and shows how to diagnose them with curl and monitoring. It also explains when a public endpoint is the bottleneck and how a dedicated RPC node can stabilize your workload.

Question 8

What makes a Solana RPC fast, and how do you choose the fastest RPC for your app?

Accepted Answer

Solana's performance demands low-latency RPC infrastructure. The fastest RPC for your use case depends on workload type, geographic proximity, and whether you need shared or dedicated resources. This article explains the key factors that affect Solana RPC speed and how to evaluate providers.

Question 9

How do the rate limiting options compare among the top Solana RPC providers?

Accepted Answer

Solana RPC providers differ in how they enforce rate limits: some cap requests per second per IP, others meter by compute units or credits, and premium tiers offer higher throughput or dedicated nodes. This article compares the rate limiting models of leading providers and helps you choose the right plan for your workload.

Question 10

What is JSON RPC Solana and how do you use it?

Accepted Answer

Solana's JSON-RPC API is the standard way for applications to interact with the network—querying accounts, submitting transactions, and subscribing to real-time updates. This article explains the core methods, how to connect to an endpoint, and common pitfalls to avoid when building on Solana.

Question 11

How to Choose a Solana WebSocket Infrastructure Provider

Accepted Answer

Solana WebSocket infrastructure powers real-time account subscriptions, transaction monitoring, and order book streaming. Choosing the right provider depends on your workload: public endpoints are fine for prototyping, but production apps need managed or dedicated nodes with stable connections and low latency. This guide compares provider types and gives you a practical evaluation framework.

Question 12

Solana WebSocket API: How to Stream Real-Time Data from the Chain

Accepted Answer

The Solana WebSocket API lets you subscribe to real-time updates like account changes, transaction confirmations, and new slots without polling. This article explains the core subscription methods, how to connect to a WebSocket endpoint, and how to handle common failure modes in production.
