About Avalanche

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.

FAQ

Frequently Asked Questions

Everything you need to know about Avalanche RPC endpoints

Quick Answer: What is Avalanche RPC?

Avalanche RPC (Remote Procedure Call) is an interface that allows developers to interact with the Avalanche blockchain. It enables you to read data, send transactions, and deploy smart contracts programmatically using standard JSON-RPC methods. Our free tier provides 5 requests per minute with no registration required, perfect for testing and development. For production applications, upgrade to Tatum Premium for 200 requests per second and enterprise-grade reliability.

How do I connect to Avalanche using these RPC endpoints?

Simply copy the RPC endpoint URL from above and configure it in your Web3 library (ethers.js, web3.js), wallet (MetaMask, Trust Wallet), or development tool (Hardhat, Truffle). The endpoint works immediately with no registration required for the free tier.

What are the rate limits for free Avalanche RPC?

Free tier RPC endpoints are limited to 5 requests per minute. This is perfect for testing and development. For production applications, we recommend upgrading to Tatum Premium which offers 200 requests per second with no daily limits.

When should I upgrade to Premium?

Consider upgrading to Premium when you're moving to production, need higher rate limits (200 req/sec), require 99.9% uptime SLA, want access to archive nodes for historical data, or need advanced features like batch RPC calls, debug/trace methods, and priority support.

Is Avalanche RPC free forever?

Yes! Our free tier Avalanche RPC endpoints are free forever with 5 requests per minute. This tier is perfect for learning, testing, and small projects. There are no hidden fees or time limits on the free tier.

What happens if I exceed the free tier rate limit for Avalanche RPC?

If you exceed 5 requests per minute on the free tier Avalanche RPC, you'll receive an HTTP 429 (Too Many Requests) error. This is a standard rate limiting response. To avoid this, you can upgrade to Tatum Premium which offers 200 requests per second with no daily limits, perfect for production applications.

Can I use these Avalanche RPC endpoints with MetaMask?

Yes! You can configure MetaMask to use our Avalanche RPC endpoints. Simply copy the endpoint URL from above, go to MetaMask Settings > Networks > Add Network (or edit existing), and paste the RPC URL. This works with all EVM-compatible blockchains including Avalanche.

Are the Avalanche RPC endpoints secure?

Yes, all our Avalanche RPC endpoints use HTTPS encryption and follow enterprise-grade security practices. They're powered by Tatum's infrastructure which maintains 99.99% uptime and is trusted by thousands of developers worldwide.

What's the difference between Avalanche mainnet and testnet RPC endpoints?

Mainnet endpoints connect to the live Avalanche blockchain where real transactions occur with real assets. Testnet endpoints connect to a separate testing network with free test tokens. Always test your dApp on Avalanche testnet before deploying to mainnet.

How do I troubleshoot Avalanche RPC connection errors?

If you're experiencing connection errors with Avalanche RPC, check: 1) The RPC endpoint URL is correct, 2) You're not exceeding rate limits (5 req/min for free tier), 3) Your network allows HTTPS connections, 4) The Avalanche network is currently operational. For persistent issues, check our status page or contact support.

What's the difference between mainnet and testnet?

Mainnet is the live Avalanche blockchain where real transactions occur with real assets. Testnet is a separate network used for testing and development with free test tokens. Always test your dApp on testnet before deploying to mainnet.

Can I use these endpoints in production?

Free tier endpoints can be used in production for low-traffic applications (under 5 req/min). For production apps with higher traffic, we strongly recommend Tatum Premium for guaranteed uptime, faster rate limits, and enterprise SLA.
