The Cardano RPC documentation provides developers with the tools to interact programmatically with the Cardano blockchain. The guide includes detailed API endpoints for querying blockchain data, managing transactions, and interacting with smart contracts on Cardano’s secure, proof-of-stake (PoS) network. Cardano’s dual-layer architecture, designed for scalability and security, supports the development of decentralized applications in a sustainable manner. Developers can use this documentation to efficiently build and deploy dApps while adhering to Cardano’s best practices.
