Data Indexers


Welcome to the Analytics page, a comprehensive hub dedicated to interacting with data services, analytic tooling on ZKsync Era. Each guide includes hands-on examples, ensuring that both newcomers and experienced developers can seamlessly harness the power of the analytical tooling within the ZKsync Era.

For an extended list of options within the ZKsync ecosystem, feel free to explore the infrastructure and developer tools categories on Dappradar.


Covalent provides the industry-leading Unified API bringing visibility to billions of Web3 data points. Developers use Covalent to build exciting multi-chain applications like crypto wallets, NFT galleries, and investor dashboard tools utilizing data.


DipDup is a Python framework for building smart contract indexers. It helps developers focus on business logic instead of writing a boilerplate to store and serve data. DipDup-based indexers are selective, which means only required data is requested. This approach allows to achieve faster indexing times and decreased load on underlying APIs.


Dune is a powerful data indexing service for blockchain, providing a comprehensive platform to query, visualize, share, and export data across 30+ blockchains. It enables users to collaboratively build and analyze blockchain data with the support of Web3's largest data community, making it an essential tool for anyone involved in the crypto space.


Flair offers reusable indexing primitives (such as fault-tolerant RPC ingestors, custom processors, re-org aware database integrations) to make it easy to receive, transform, store and access your on-chain data.


Goldsky is a data indexer for web3 builders, offering high-performance subgraph hosting and realtime data replication pipelines. Goldsky offers two core self-serve products, Subgraphs and Mirror, that can be used independently or in conjunction to power your data stack.

Graph Network

The Graph is a decentralized protocol for indexing and querying blockchain data. The Graph makes it possible to query data that is difficult to query directly. Use The Graph network today to index protocol data on ZKsync!

Space & Time

Space and Time is the verifiable compute layer that scales zero-knowledge proofs on a decentralized data warehouse to deliver trustless data processing to smart contracts, LLMs, and enterprises. Space and Time joins indexed blockchain data from major chains with offchain datasets.

SubQuery Network

SubQuery is a fast, flexible, and reliable open-source data indexer that provides you with custom APIs for your web3 project across all of our supported chains.


Subsquid is a decentralized indexing toolkit optimized for batch extraction of large volumes of data. It currently serves historical on-chain data including event logs, transaction receipts, traces and per-transaction state diffs. Subsquid offers a powerful toolkit for creating custom data extraction and processing pipelines, achieving indexing speeds of up to 150k blocks per second.
