About the company
Espresso's mission is to bring Web3 applications like decentralized finance, NFTs, and DAOs to the mainstream by making them cheaper, scalable, and more private for users.
Espresso is focused on achieving cheaper transactions than any other blockchain scaling solution through a new proof-of-stake protocol that integrates a decentralized ZK-Rollup.
This protocol acts as both as a standalone platform and also a solution to be used by existing blockchains like Ethereum.
In addition to scalability, Espresso supports applications with greater privacy guarantees than exist in today's smart contract ecosystems.
Leveraging zero-knowledge proofs, Espresso has developed the Configurable Asset Privacy (CAP) protocol that allows developers to determine what transactional data remains private and for whom.
Contributors to Espresso comprise a diverse team located around the world. We are passionate about building a better infrastructure for how we transact and interact online.
We are builders, designers, researchers, and hackers and have contributed in academia, in open source communities, in policymaking, and beyond.
We are backed by over $30mm in funding from leading investors in technology and crypto including Greylock Partners, Electric Capital, Sequoia Capital, and Polychain Capital.
