About Gnosis

The Gnosis mission has always been centered on building decentralized infrastructure for the Ethereum ecosystem. When Gnosis was founded in 2015, it focused on building prediction markets to enable worldwide access to accurate information. While creating the prediction market platform, it became clear that Gnosis needed to build the infrastructure required to support it.

As a DAO, Gnosis uses the products that it creates to transparently guide decisions on the development, support, and governance of its ecosystem.

Gnosis Safe (multisig and programmable account), Cow Protocol (formerly CowSwap and Gnosis Protocol), Conditional Tokens (prediction markets), Gnosis Auction, and Zodiac (standard and tooling for composable DAOs) are all products incubated by Gnosis. Their success is demonstrated by the recent spin-out of Cow Protocol and the formation of SafeDAO. By combining needs-driven development with deep technical expertise, Gnosis has built the decentralized infrastructure for the Ethereum ecosystem.
