The Cosmos SDK is a modular framework for building blockchain applications in Go. Gaia, the implementation of the Cosmos Hub, is built with the Cosmos SDK.

Client Libraries

Go Ignite CLI - All-in-one platform to build, launch, and maintain any crypto application on a sovereign and secured blockchain. Quickly bootstraps a new Cosmos SDK blockchain with UI and support to create new and work conveniently with existing Cosmos SDK modules.

JavaScript

cosmos/cosmjs - The Cosmos JavaScript library.

telescope - Typescript library generator built on top of CosmJS. chainapsis/cosmosjs - Chainapsis Signing & API Library.

cosmos-client/cosmos-client-ts - JavaScript / TypeScript client for Cosmos SDK blockchains.

cosmos/sig - Cosmos Signing Library.

cosmology-tech/chain-registry - A npm package for the official Cosmos Chain Registry.

strangelove-ventures/graz - Collection of React hooks to interact with wallets, signers, signing clients, etc.

cosmology-tech/create-cosmos-app - A npm package to bootstrap a Cosmos Web UI.

Python cosmospy - Tools for Cosmos wallet management and offline transaction signing.

cosmpy - A Python client library for interacting with blockchains based on the Cosmos-SDK.

pyCosmicWrap - A python3 wrapper around Cosmos API/RPC.

Rust CosmWasm/cosmwasm - WebAssembly Smart Contracts for the Cosmos SDK.

iqlusioninc/stdtx - A collection of open source Rust crates from iqlusion.

peggyjv/ocular - A client library for Cosmos SDK chains focusing on pleasant UX.

Block Explorers

• ATOMScan
• Big Dipper - Source
• IOBScan
• Mintscan
• Mintscan for Cosmos Hub Testnet
• NG Explorers
• Ping.pub - Source
• Stake ID

Visual Block Explorers View Inter-Blockchain Communication (IBC) transfer activity. The map traces IBC transactions between different blockchains (called zones in the Cosmos Hub) to display accurate aggregate information about the pulse of the entire Cosmos ecosystem.

• Map of Zones - Source
• Mintscan - Interchain Explorer by Cosmostation.

Chain Registry

A registry containing standardized metadata from most Cosmos chains.

• cosmos/chain-registry
• Cosmos Directory - Source
• cosmology-tech/chain-registry - A npm package for the official Cosmos Chain Registry.

Validators

Popular block explorers provide a list of active validators. The easiest entry point to view validator profiles is from a block explorer:

• List on Mintscan
• List on ATOMScan
• List on BigDipper
• List on Kujira POD

DYOR when choosing a validator. Consider delegating your tokens to validators outside of the top 20 to increase the decentralization of the network. This is also a good pratice to avoid 0% commission validators and exchange validators.

Cosmos SDK Modules

The best place to find an accurate list of the Cosmos SDK modules is the project repository:

• For a list of production-grade modules, see the List of Modules.
• For a list of well-known third-party modules, see the Ecosystem section of the Cosmos SDK documentation.

Some modules are important but may still lack official documentation, like the genutil module that is essential to launch a chain. Please consider contributing documentation to the Cosmos SDK to help fill these gaps.

To share a module that you want the community to know about and use, add it here. You can also create a pull request (PR) to add the module to the official project.
