zkSync ERA is a Layer-2 protocol that uses ZK technology to scale Ethereum while maintaining its values of freedom, self-sovereignty, and decentralization. Its goal is to achieve hyper scalability by processing unlimited transactions without compromising security or cost. It focuses on self-custody and intuitive UX to onboard the first billion users to web3. Over 200 projects have registered their interest in deploying on zkSync ERA, and it has raised capital from top investors in the industry and is backed by Matter Labs.
