About Polygon
The Polygon RPC documentation provides developers with the necessary tools to interact with the Polygon blockchain, a Layer 2 scaling solution built on Ethereum. The documentation includes API endpoints for querying blockchain data, managing transactions, and deploying smart contracts. Polygon uses sidechains and rollups to achieve fast and low-cost transactions, making it ideal for decentralized finance (DeFi), gaming, and NFTs. Developers can leverage Ethereum-compatible tools while benefiting from enhanced scalability using Polygon’s RPC gateway.

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