Solana RPC Endpoints & API | OnFinality

Solana RPC Endpoints on OnFinality

Solana is a high-performance blockchain designed for decentralized applications and crypto-native products. Its proof-of-stake consensus and parallel transaction processing enable fast, low-cost interactions. For developers, reliable RPC access is critical to building responsive wallets, DeFi platforms, NFT marketplaces, and backend services.

OnFinality provides managed Solana RPC endpoints for mainnet, giving teams authenticated access to the Solana JSON-RPC API over HTTP and WebSocket. Whether you are prototyping or running production workloads, OnFinality offers a scalable path from shared endpoints to higher-capacity plans.

Why Use OnFinality for Solana RPC?

• Authenticated Access: Get a dedicated API key and endpoint through the OnFinality dashboard, avoiding the rate limits and instability of public endpoints.
• Archive Support: Access historical state data for analytics, compliance, or debugging — available depending on your plan.
• Observability: Monitor request volume, error rates, and usage patterns to optimize your application.
• Global Regions: Endpoints available in N. Virginia and Hong Kong to reduce latency for your users.
• Production Ready: OnFinality endpoints are designed for team projects, backend services, and higher-volume workloads.

Solana RPC Methods You Can Use

OnFinality supports the full Solana JSON-RPC API. Common methods include:

• getBalance – Check SOL balances.
• getAccountInfo – Retrieve account data.
• getTransaction – Fetch transaction details.
• sendTransaction – Submit signed transactions.
• getEpochInfo – Get current epoch information.
• getProgramAccounts – Query accounts owned by a program.

For a complete list, refer to the Solana RPC HTTP Methods documentation.

How to Connect

1. Create or sign in to your OnFinality account.
2. Select Solana from the supported networks list.
3. Create an API endpoint (shared or dedicated).
4. Test your connection using getEpochInfo or getHealth.
5. Monitor usage and scale as needed.

Public vs Private Solana RPC

Public endpoints (e.g., https://api.mainnet.solana.com) are suitable for lightweight testing but often suffer from rate limits and lack of support. OnFinality's authenticated endpoints provide clearer limits, request analytics, and a path to dedicated infrastructure.

Get Started

OnFinality makes it easy to integrate Solana RPC into your stack. Start with a free tier to evaluate performance, then upgrade as your project grows. No need to run your own node — focus on building.
