About The Open Network
The TON API documentation provides developers with the tools to interact programmatically with The Open Network blockchain. It covers fetching account information, calling smart contract `get methods` for precise data retrieval, and fetching account transactions. The API utilizes HTTP-based JSON-RPC endpoints, with TON Center being a recommended provider. This interface is essential for building decentralized applications that need to read and interact with the TON blockchain efficiently.

FAQ
Frequently Asked Questions
Everything you need to know about The Open Network RPC endpoints
What is The Open Network RPC?
The Open Network RPC (Remote Procedure Call) is an interface that allows developers to interact with the The Open Network blockchain. It enables you to read data, send transactions, and deploy smart contracts programmatically using standard JSON-RPC methods.
How do I connect to The Open Network 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 The Open Network 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 The Open Network RPC free forever?
Yes! Our free tier The Open Network 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's the difference between mainnet and testnet?
Mainnet is the live The Open Network 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.
