Mainnet is the live network: every write is final and carries real value, so it is the right choice once your integration is tested and ready for production traffic, or whenever you only need to read live state such as balances, blocks, or confirmed transactions.
Testnet mirrors the same interface but runs on a network built for experimentation, funded with free test tokens that have no market value. Point your local development environment at testnet first so you can retry failed calls, simulate edge cases, and iterate on contract logic without financial risk, then switch the RPC URL to mainnet once your code is stable.
The interface names shown above (JSON-RPC (C-Chain), JSON-RPC (P-Chain), JSON-RPC (X-Chain)) follow different conventions worth knowing before you integrate. JSON-RPC exposes a single HTTP endpoint that accepts method calls in a JSON envelope, and most Web3 libraries speak it natively. REST exposes resources over standard HTTP verbs, which is often simpler for services outside the Web3 stack to consume without a specialized client. gRPC uses binary protobuf messages over HTTP/2, trading a generated client for lower latency and smaller payloads. Pick whichever interface matches the tooling your stack already uses.
The Avalanche RPC documentation provides developers with a detailed guide to interact programmatically with the Avalanche network. This guide covers the various API endpoints for managing blockchain data, executing smart contracts, and submitting transactions across the C-Chain (EVM-compatible), X-Chain, and P-Chain. With its high throughput and customizable subnets, Avalanche offers a scalable environment for building decentralized applications. The RPC documentation includes best practices and examples to simplify integration with the Avalanche blockchain ecosystem.

Everything you need to know about Avalanche RPC endpoints
RPC (Remote Procedure Call) is the standard way to interact with the network programmatically - reading on-chain data, submitting transactions, and deploying smart contracts through JSON-RPC calls. The free tier ships 5 requests per minute with no registration required, which covers most learning and testing workflows. Production applications typically move to Tatum Premium for 200 requests per second and enterprise-grade reliability.
