Question 1

Scalable Solana gRPC Endpoints for Enterprise Use: What to Evaluate

Accepted Answer

Solana's gRPC interfaces (Geyser plugin streams and the Yellowstone-style gRPC proxy) push account, slot, block, and transaction updates to your backend instead of forcing you to poll JSON-RPC. For enterprise workloads, the hard part is not finding a gRPC endpoint but finding one that scales with your subscriber count, keeps streams stable during congestion, and gives you a clear path to dedicated capacity when shared limits are not enough.

This article explains how Solana gRPC streaming differs from standard RPC, what to check before you commit to a provider, and how to combine a scalable gRPC stream with reliable JSON-RPC and WebSocket endpoints. OnFinality offers Solana RPC API access and dedicated node infrastructure, so you can start on shared endpoints and move to isolated capacity as your indexing or trading volume grows.

Question 2

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 3

How do Solana RPC providers compare on rate limits and usage tiers?

Accepted Answer

Compare Solana RPC providers by rate limits, usage tiers, and request types. Learn what to check before choosing a provider, and how to match your workload to the right plan.

Question 4

How to Choose a Solana RPC Provider with Competitive Pricing and Robust Developer Tools for Startups

Accepted Answer

Startups building on Solana need an RPC provider that balances predictable pricing with the developer tools that speed up iteration. This guide breaks down the key evaluation criteria—pricing models, rate limits, WebSocket support, archive data, and developer experience—so you can compare providers without overpaying or outgrowing your infrastructure.

We cover what to look for in a Solana RPC provider, how to match your workload to the right plan, and where OnFinality fits as a managed RPC option with transparent pricing and dedicated node support. You'll leave with a clear checklist to evaluate providers against your startup's actual needs.

Question 5

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 6

How do I connect to the Solana devnet API for testing?

Accepted Answer

The Solana devnet is a public test cluster where developers can deploy and test programs, run transactions, and validate client logic without risking real funds. Connecting to a reliable devnet RPC API is the first step for building and debugging Solana applications.

This guide explains how to configure your Solana tooling for devnet, get test SOL from the faucet, and choose an RPC endpoint that matches your development workflow. Whether you are using the Solana CLI, web3.js, or a custom backend, you will find practical setup steps and troubleshooting tips here.

Question 7

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 8

What is a Solana RPC service and how do you choose one?

Accepted Answer

A Solana RPC service provides the API endpoints your dApp, indexer, or trading bot needs to read chain state and submit transactions. Choosing the right service depends on your workload, traffic patterns, and whether you need dedicated capacity or shared public endpoints. This article explains what to evaluate and how to match a service to your use case.

Question 9

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 10

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 11

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 12

Solana Public RPC Endpoints: Which One Should You Use?

Accepted Answer

Solana public RPC endpoints let you query the network without running your own validator. This article compares the default public endpoint with managed options like OnFinality, explains rate limits and reliability tradeoffs, and shows how to connect via HTTP and WebSocket for production apps.
