The Cosmos SDK is a framework for building blockchain applications.CometBFT (BFT Consensus) and the Cosmos SDK are written in the Go programming language. Cosmos SDK is used to buildGaia, the implementation of the Cosmos Hub.

WARNING: The Cosmos SDK has mostly stabilized, but we are still making some breaking changes.

Note: Always use the latest maintainedGo version for building Cosmos SDK applications.

To learn how the Cosmos SDK works from a high-level perspective, see the Cosmos SDKHigh-Level Intro.

If you want to get started quickly and learn how to build on top of Cosmos SDK, visitCosmos SDK Tutorials. You can also fork the tutorial's repository to get started building your own Cosmos SDK application.

For more information, see theCosmos SDK Documentation.

SeeCONTRIBUTING.md for details on how to contribute and participate in ourdev calls.If you want to follow the updates or learn more about the latest design then join ourDiscord.

The Cosmos ecosystem is vast.Awesome Cosmos is a community-curated list of notable frameworks, modules and tools.

The IBC module for the Cosmos SDK has its owncosmos/ibc-go repository. Go there to build and integrate with the IBC module.

The version matrix below shows which versions of the Cosmos SDK, modules and libraries are compatible with each other.

Core dependencies are the core libraries that an application may depend on.Core dependencies not mentioned here as compatible across all maintained SDK versions.

Module Dependencies are the modules that an application may depend on and which version of the Cosmos SDK they are compatible with.

Note: The version table only goes back to 0.50.x, as modules started to become modular with 0.50.z.X signals that the module was not spun out into its own go.mod file.N/A signals that the module was not available in the Cosmos SDK at that time.

This Cosmos SDK project is not related to theReact-Cosmos project (yet). Many thanks to Evan Coury and Ovidiu(@skidding) for this Github organization name. As per our agreement, this disambiguation notice will stay here.
