Summary
ZKsync Era is one of the largest Ethereum Layer-2 rollups by total value locked, yet comprehensive empirical data about its operation has been scarce. We present a public dataset that captures 18 months of ZKsync Era transactions, blocks, and protocol events, comprising over 300 million transactions. The dataset includes detailed information about transaction types, smart contract interactions, L1-to-L2 messaging, and proof submissions. We demonstrate the utility of the dataset through several case studies: analyzing the adoption of ZKsync's native account abstraction features, measuring the cost of privacy on Layer 2, and characterizing the behavior of MEV extractors within the rollup environment. This dataset, which we commit to maintaining and updating, provides a foundation for empirical studies of ZK-rollup economics, security, and user behavior.
