Question 1

Solana Public RPC Endpoints

Accepted Answer

Solana public RPC endpoints are free, shared JSON-RPC gateways that let developers read network state, send transactions, and subscribe to updates without running their own node. The mainnet endpoint is `https://api.mainnet-beta.solana.com`; Devnet uses `https://api.devnet.solana.com`. They require no API key and support standard Solana RPC methods, which makes them convenient for prototyping, development, and low-volume testing. Public endpoints are shared across all users, so the operator enforces rate limits and can change them without notice. They do not provide archive data by default, WebSocket capacity is shared, and there is no uptime guarantee. That makes them unsuitable for production dApps with real users or high request volumes. For development, use Devnet and test SOL from the official faucet. For production, a managed Solana RPC service or dedicated node provides predictable capacity, HTTP/WebSocket access, archive support, and a support path. Before choosing, estimate request volume, required RPC methods, and latency expectations. Always check the current Solana cluster documentation before relying on a public endpoint.

Question 2

Solana RPC Providers for Mainnet, Devnet & Testnet

Accepted Answer

A practical Solana RPC setup covers more than one endpoint. Mainnet is the production cluster where real SOL and user traffic live. Devnet is the development cluster for testing programs and transactions with free test SOL from the official faucet at https://faucet.solana.com. Testnet is a separate cluster used for validator performance, network upgrades, and release exercises; it is not a general application testing environment. Public endpoints—https://api.mainnet-beta.solana.com for mainnet and https://api.devnet.solana.com for devnet—are available, but they are rate-limited and best for light tests. Managed RPC providers can offer authenticated endpoints, clearer limits, WebSocket support, and better observability across environments. Evaluate providers by whether they support the exact environments your team uses, match your RPC method mix, and provide a path from shared to dedicated capacity. OnFinality maintains Solana mainnet and Devnet resources; check the current plan for testnet coverage. Start with Devnet for iterating, use Mainnet for production, and keep environment configuration separate. Always verify current rate limits and endpoint availability in official or provider documentation, because they can change.

Question 3

Solana Devnet RPC: Endpoint, Faucet & Developer Setup

Accepted Answer

Solana Devnet is a public test cluster for building and testing Solana programs with free test SOL—no real value. The primary public RPC endpoint is `https://api.devnet.solana.com`, with WebSocket support at `wss://api.devnet.solana.com`. This endpoint is free but shared, and Solana enforces rate limits that can change; for heavy development, QA, or CI pipelines, a managed RPC provider is often more reliable.

To get started, request test SOL from the official faucet at `https://faucet.solana.com` or use the Solana CLI airdrop. Configure the Solana CLI with `solana config set --url devnet`, or in JavaScript/TypeScript create a `Connection` using the Devnet URL via `@solana/web3.js`. For production-like testing or repeated runs, evaluate a managed Devnet RPC endpoint such as OnFinality’s Solana Devnet offering—check the [network page](/networks/solana-devnet) for current endpoint options and WebSocket access. Remember: Devnet is for development and testing only; never deploy production workloads there. Choose a setup that matches your request volume, observation needs, and path to mainnet.

Question 4

How should developers evaluate RPC endpoints across Sepolia, Polygon, Solana Devnet, Base Sepolia, and peaq?

Accepted Answer

Choosing the right RPC endpoint is critical for dApp performance and reliability. This guide walks through key evaluation criteria—rate limits, chain IDs, testnet reliability, and when to upgrade to managed or dedicated infrastructure—across five popular networks: Ethereum Sepolia, Polygon, Solana Devnet, Base Sepolia, and peaq. Whether you're prototyping on a testnet or scaling on mainnet, understanding these factors helps you avoid bottlenecks and ensure smooth development.

In practice, the useful question is not just whether an endpoint exists. Teams should check Solana methods, devnet support, request patterns, and whether shared or dedicated access fits the workload. That turns the page from a definition into a decision tool: it helps you decide what to test first, what belongs in staging, and when a production workload may need stronger isolation or clearer request visibility. If you already know the network you need, open /networks/eth-sepolia after using this checklist so you can test the endpoint against your real methods.

Question 5

5 Best Solana RPC Providers in 2026: Pricing & Features Compared

Accepted Answer

Compare OnFinality, Chainstack, Helius, Alchemy and QuickNode for Solana RPC. Start with the methods your wallet, application or indexer needs, then compare request budgets, WebSocket subscriptions, historical queries and streaming options. OnFinality combines managed Solana JSON-RPC and WebSocket access with usage visibility and dedicated-node options; specialized streaming products require a separate comparison.
