zkSync Era

What is zkSync Era?

zkSync Era is a Layer 2 ZK rollup, a trustless protocol that uses cryptographic validity proofs to provide scalable and low-cost transactions on Ethereum.

ZK Chains

ZK chains are high performance, verifiable, modular rollups and validiums powered by zkSync. United in an elastic network, ZK chains can be added or expanded to handle increased transaction volume without affecting costs or hardware requirements for verification.

ZK Stack

zkSync offers secure one-tap onboarding via FaceID/Passkeys, eliminating the need for seed phrases and reducing the risk of hacks. By automatically creating modular smart accounts at the protocol level, zkSync enables a delightful, customizable UX, allowing users to seamlessly access all ZK chains with what feels like a single account directly from their application.
