ZKsync Era

Open Source

Matter Labs' EVM-compatible ZK rollup, with its zkEVM circuits, prover (Boojum), and node software fully open source.

About

ZKsync Era is the EVM-compatible zero-knowledge rollup built by Matter Labs, whose sequencer, zkEVM circuits, and Boojum proving system are published as open source. It is security-relevant both as widely used infrastructure and as a case study: ChainLight's 2023 discovery of an under-constrained circuit bug in Era's proof system (responsibly disclosed and paid via bounty) is one of the best-documented ZK circuit vulnerabilities in a production system. The codebase is a common reference for engineers studying production zkEVM circuit design and its failure modes.
