About Ethereum Classic

The Ethereum Classic RPC documentation offers a detailed guide for developers to interact programmatically with the Ethereum Classic blockchain. This immutable network preserves the original Ethereum chain after the DAO fork, supporting smart contracts and dApps through the EVM. Developers can leverage the RPC endpoints to query the blockchain, submit transactions, and manage smart contracts. With its proof-of-work (PoW) consensus, Ethereum Classic offers a secure and decentralized environment for building reliable applications.

FAQ

Frequently Asked Questions

Everything you need to know about Ethereum Classic RPC endpoints

Quick Answer: What is Ethereum Classic RPC?

Ethereum Classic RPC (Remote Procedure Call) is an interface that allows developers to interact with the Ethereum Classic 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.

What is Ethereum Classic RPC?

How do I connect to Ethereum Classic 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 Ethereum Classic 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 Ethereum Classic RPC free forever?

Yes! Our free tier Ethereum Classic 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 Ethereum Classic RPC?

If you exceed 5 requests per minute on the free tier Ethereum Classic 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 Ethereum Classic RPC endpoints with MetaMask?

Yes! You can configure MetaMask to use our Ethereum Classic 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 Ethereum Classic.

Are the Ethereum Classic RPC endpoints secure?

Yes, all our Ethereum Classic 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 Ethereum Classic mainnet and testnet RPC endpoints?

Mainnet endpoints connect to the live Ethereum Classic 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 Ethereum Classic testnet before deploying to mainnet.

How do I troubleshoot Ethereum Classic RPC connection errors?

If you're experiencing connection errors with Ethereum Classic 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 Ethereum Classic 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 Ethereum Classic 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.
