Discover Avalanche, a fast and scalable blockchain with RPC access. Build dApps using its customizable subnets and comprehensive documentation.
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.
