Interchain Foundation funds the development of the interchain stack: open source protocols, libraries, and tools for interconnected chains. In addition to the foundational IBC protocol, our teams maintain Cosmos SDK, CometBFT, IBC, CosmWasm, and CosmJS.
Interchain Stack
The interchain stack is an architecture for scalable, secure, and interconnected blockchain-based apps and services. It utilizes IBC, the best-in-class bridging technology, and libraries for chain interoperability.
Cosmos SDK
The world's most popular framework for building application-specific blockchains.
