About Binance Smart Chain
Binance Smart Chain’s (BSC) RPC documentation serves as a detailed resource for developers to interact programmatically with the BSC blockchain. The API endpoints provided allow for querying blockchain data, submitting transactions, and managing smart contracts, leveraging BSC’s proof-of-staked authority (PoSA) consensus. BSC’s compatibility with Ethereum’s tooling, along with its fast finality and low transaction fees, make it an ideal platform for DeFi, NFT, and gaming dApps. The documentation also includes best practices for integration and scalability.

How do I connect to Binance Smart Chain 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 Binance Smart Chain 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 Binance Smart Chain RPC free forever?
Yes! Our free tier Binance Smart Chain 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 Binance Smart Chain RPC?
If you exceed 5 requests per minute on the free tier Binance Smart Chain 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 Binance Smart Chain RPC endpoints with MetaMask?
Yes! You can configure MetaMask to use our Binance Smart Chain 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 Binance Smart Chain.
Are the Binance Smart Chain RPC endpoints secure?
Yes, all our Binance Smart Chain 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 Binance Smart Chain mainnet and testnet RPC endpoints?
Mainnet endpoints connect to the live Binance Smart Chain 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 Binance Smart Chain testnet before deploying to mainnet.
How do I troubleshoot Binance Smart Chain RPC connection errors?
If you're experiencing connection errors with Binance Smart Chain 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 Binance Smart Chain 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 Binance Smart Chain 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.
