About Bitcoin
Bitcoin’s RPC documentation offers developers a comprehensive guide to programmatically interact with the original blockchain network. This documentation details the API endpoints needed to query transaction data, submit new transactions, and manage wallets. Operating on a proof-of-work (PoW) consensus mechanism, Bitcoin ensures security and decentralization at scale. Developers can utilize the RPC gateway to build applications such as payment gateways and wallets while leveraging Bitcoin’s global recognition and robust infrastructure.

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