🗃️Data Sources

Where does Nansen get its data.

Blockchain ETL

Nansen's founders created the Blockchain ETL project in order to facilitate data science using blockchain data. The source code for the Blockchain ETL project is located here: https://github.com/blockchain-etl.

Blockchain ETL extracts data from different blockchain nodes and applies smart contract specific processing to convert blockchain data into data that can be stored in and processed with different types of data warehouses.

Supported Blockchains

Nansen Query supports 20+ blockchains and is constantly in the process of adding more chains. If you'd like support for a new chain, please provide feedback to us here. If you work at a blockchain and would like to speak with us about integration with Nansen, please contact us here.

As of Q1 2023, Nansen Query provides data coverage for 95+% of on-chain total value locked (TVL), which can provide a true picture of the actual state of blockchain usage, as well as deeper insights into sector trends and capital movements.

Some blockchains may have more comprehensive data than others. We're working on making sure all blockchains have the same level of comprehensive data.
