About us

OpenZeppelin is a leading cybersecurity company that provides security products to build, automate, and operate decentralized applications.

With a mission to protect the open economy, our team created the most popular open source library for smart contract development with over 4 million downloads. Our unique expertise subsequently allowed us to uncover major security vulnerabilities for the Ethereum Foundation, MakerDAO, and Facebook’s Libra, and conduct security audits for many top blockchain companies including Coinbase, Brave, Compound, Aave, and Augur.

Building on this experience, we recently launched a platform to help teams automate their Ethereum operations and securely ship products faster: OpenZeppelin Defender.

With the success of our products, security audit work, and open source educational efforts, we are setting industry standards for building secure systems in a fast-growing industry that is creating an open financial system for the world.
