Solana RPC Endpoints & API for dApp Development

Solana RPC & API Access

Solana is a high-performance blockchain built for decentralized applications, DeFi, NFTs, and other crypto-native products. Its proof-of-stake consensus and parallel transaction processing keep fees low and throughput high—but only if your RPC connection keeps up.

OnFinality provides managed Solana API endpoints for mainnet. You get authenticated access to the Solana JSON-RPC API without running your own node. Start with a shared endpoint to prototype, then scale to a higher-capacity plan as your traffic grows.

What to check first

• Connection test: Use getHealth or getEpochInfo to confirm your endpoint is live.
• Balance & accounts: getBalance and getAccountInfo are the most common starting points.
• Transaction flow: sendTransaction and getTransaction cover the core send-and-verify loop.
• Program queries: getProgramAccounts is essential for dApps that need to scan program-owned accounts.
• Epoch data: getEpochInfo helps you align with Solana's slot schedule.

Planning for production

• Regions: Endpoints are available in N. Virginia and Hong Kong. Choose the region closest to your user base or infrastructure.
• Observability: The OnFinality dashboard shows request volume, error rates, and usage patterns—useful for tuning your app before launch.
• Capacity: Shared endpoints work for development and low-traffic apps. For higher throughput, review the available plans in the dashboard.

• Create a Solana API endpoint
• Review pricing plans

Solana RPC and developer resources

Solana workloads tend to be sensitive to fresh chain data and backend reliability, so the page should make connection checks, supported access, and growth paths easy to scan.

Best fit: mainnet production workflows for wallets, bots, and low-latency app backends.

What builders usually check first:

• Fetch recent block, account, and program data for apps, bots, and dashboards.
• Support wallet, DeFi, trading, or consumer-product backends that need frequent chain reads.
• Keep a clear upgrade path when request volume or operational sensitivity grows.

Supported capability notes:

• Authenticated Solana RPC/API access for wallets, bots, and low-latency app backends.
• HTTP and WebSocket support for app, backend, and integration workflows.
• Archive access for historical state, analytics, or compliance-style queries.

Decision notes:

• Environment: mainnet. Protocol family: Solana JSON-RPC.
• HTTP and WebSocket support is listed for supported app and backend workflows.
• Archive support is available for historical state or older chain-data queries.
• Available regions listed by the network spec include N.Virginia, Hong Kong.

A quick connection check usually starts with getEpochInfo, then moves into the exact methods your wallet, dashboard, bot, indexer, or backend service needs.

Planning the next step:

• Shared RPC is a practical starting point for integration, prototypes, dashboards, and many app backends.
• If your product becomes traffic-heavy or operationally sensitive, review the available upgrade path before relying on a single access pattern.
