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: .

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

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.
