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.

Connect to Avalanche and Fetch the Latest Block

This widget lets you instantly query the latest block height (or equivalent) for Avalanche using a chain-specific RPC method like eth_blockNumber, getblockcount, or getBlockHeight. Useful for connectivity checks, uptime monitoring, or API testing.

Retrieve Avalanche Node Status or Client Version via RPC

Use this pre-configured request to get version or status information for your connected Avalanche node. Whether it's web3_clientVersion, getblockchaininfo, or chain-specific endpoints, the method is optimized for each supported blockchain.

Test Avalanche RPC Methods in Postman

Explore and test Avalanche blockchain methods instantly using our pre-configured Postman collection. Perfect for developers who want to experiment with Avalanche RPC endpoints, validate API responses, or integrate Avalanche into their applications.
