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.

RPC Gateway for Cosmos blockchain
Cosmos RPC networks
Connect to Cosmos and Fetch the Latest Block
This widget lets you instantly query the latest block height (or equivalent) for Cosmos using a chain-specific RPC method like eth_blockNumber, getblockcount, or getBlockHeight. Useful for connectivity checks, uptime monitoring, or API testing.
Retrieve Cosmos Node Status or Client Version via RPC
Use this pre-configured request to get version or status information for your connected Cosmos node. Whether it's web3_clientVersion, getblockchaininfo, or chain-specific endpoints, the method is optimized for each supported blockchain.
Test Cosmos RPC Methods in Postman
Explore and test Cosmos blockchain methods instantly using our pre-configured Postman collection. Perfect for developers who want to experiment with Cosmos RPC endpoints, validate API responses, or integrate Cosmos into their applications.
How to use the Cosmos Postman Collection
- Get your API key: Visit Tatum Dashboard to obtain your free API key
- Import the collection: Click the "Run in Postman" button below to import the Cosmos collection
- Configure your environment: Update the
gateway-api-keyvariable in the Tatum Gateway environment - Start testing: Execute any Cosmos RPC method and see real-time responses
Available Cosmos interfaces and methods
Each Cosmos network and interface below exposes its own set of RPC methods, listed live from Tatum's RPC Gateway. Query these endpoints for any interface to explore what it supports:
