# RPC Infrastructure ## Overview RPC endpoints are the primary way your application interacts with the Pharos Network. They allow you to send transactions, query on-chain data, and communicate with the network programmatically. As a developer, you’ll use RPCs to connect your frontend, backend, or scripts to the blockchain during development and in production. ## What You Can Do with RPC * Send transactions to the network * Read on-chain data (balances, contract state, logs) * Interact with smart contracts * Listen to events and track activity * Power applications, scripts, and integrations ## Why It Matters RPC endpoints act as the bridge between your application and the blockchain. Choosing the right provider and configuration is important for performance, reliability, and scalability. ## Available RPC Providers Pharos supports multiple RPC providers for both Mainnet and Testnet environments. * ZAN RPC * Nirvana RPC * Alchemy RPC --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
