FAQ
Frequently Asked Questions
Everything you need to know about Celo RPC endpoints
Quick Answer: What is Celo RPC?
Celo RPC (Remote Procedure Call) is an interface that allows developers to interact with the Celo 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 Celo 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 Celo 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.
Is Celo RPC free forever?
Yes! Our free tier Celo 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 Celo RPC?
If you exceed 5 requests per minute on the free tier Celo 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 Celo RPC endpoints with MetaMask?
Yes! You can configure MetaMask to use our Celo 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 Celo.
Are the Celo RPC endpoints secure?
Yes, all our Celo 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 Celo mainnet and testnet RPC endpoints?
Mainnet endpoints connect to the live Celo 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 Celo testnet before deploying to mainnet.
How do I troubleshoot Celo RPC connection errors?
If you're experiencing connection errors with Celo 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 Celo 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 Celo 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.
