We're a global team united by a bold vision.

While we're distributed, we maintain a tight-knit culture. We look for people who are collaborative, think big, but stay grounded.

About us

Gnosis boasts an unparalleled track record of experimentation and 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. Today, as a DAO, Gnosis uses the products that it creates to transparently guide decisions on the development, support, and governance of its ecosystem. Safe, Cow Protocol, Conditional Tokens, Gnosis Auction, Zodiac, Agnostic Relay, and MEV Blocker are all products and protocols incubated by Gnosis.  

In November 2021, the xDai and GnosisDAO communities voted to combine their vibrant ecosystems to create the Gnosis Chain, an EVM compatible, community owned network that prioritizes credible neutrality. Secured by over 125k validators around the world, Gnosis Chain ensures a secure and resilient infrastructure. Users and developers on Gnosis Chain can also take advantage of familiar tooling and trust-minimized bridges to the Ethereum mainnet. Gnosis Chain employs the same execution and consensus layer clients as Ethereum, ensuring seamless integration with all future EIPs.

Most recently, we launched Gnosis Pay, the first decentralized payment network allowing web3 developers to integrate with a range of traditional payment schemes including Visa. Gnosis Pay allows users to spend their digital assets anywhere Visa is accepted with the same quick, seamless transactions they expect from a traditional debit card. 

Embrace the future of decentralized technology with Gnosis Chain, and join us as we continue to shape the next generation of web3 advancements. Together, we are building a decentralized ecosystem that empowers users and fosters global innovation.
