Despite blockchain data being publicly available, practical challenges and high costs often hinder its effective use by researchers, thus limiting data-driven research and exploration in the blockchain space. This is especially true when it comes to Layer~2 (L2) ecosystems, and ZKsync, in particular. To address these issues, we have curated a dataset from 1 year of activity extracted from a ZKsync Era archive node and made it freely available to external parties. In this paper, we provide details on this dataset and how it was created, showcase a few example analyses that can be performed with it, and discuss some future research directions. We also publish and share the code used in our analysis on GitHub to promote reproducibility and to support further research.
