Discover Cosmos, a blockchain designed for interoperability. Build cross-chain decentralized applications using its RPC gateway.
Cosmos Blockchain RPC documentation serves as a comprehensive guide for developers to interact with the Cosmos network, enabling them to build and manage decentralized applications (dApps) on the Cosmos ecosystem. The documentation provides detailed information on available RPC endpoints, methods, and parameters necessary for performing tasks such as querying blockchain data, managing accounts, and broadcasting transactions. Cosmos is designed for interoperability and scalability, making it ideal for developers looking to build cross-chain decentralized applications.
