Dream. Build. Decentralize.

It's nice to meet you.

We're Greymass, an imaginative team of developers and researchers who are paving the way to a better decentralized internet.

Who do we serve?

Everyday users.

Our guiding vision is an easy Web3 user experience for everyone, whether you're a power user or just starting out. Our Anchor and Unicove products are designed to be both intuitive and safe.


As developers ourselves, we create open-source tools that we want to use and share with others. We believe that a simple development experience attracts more talent to the blockchain space.

The Antelope community.

We've been active participants in the community since Day 1, both as block producers and developers. Everything we build works with all Antelope-based blockchains including EOS, FIO, Proton, Telos, and WAX.
