Responsibly shaping a new technological paradigm.


As stewards of the interchain, we fund and advance the creation of an interoperable, sustainable, and community-owned decentralized ecosystem.


Our core teams maintain the protocols and applications Cosmos Hub, Cosmos SDK, CosmWasm, CosmJS, IBC, and CometBFT. Learn about our ecosystem and the Interchain Stack.



and interoperability.

Work on the Interchain

Our team and community are building a future in which interoperable sovereignty can thrive, with incentive-aligned public goods development, and a future-proof decentralized tech stack.
