Decoded Contracts

In addition to raw blockchain events, Nansen Query also host the largest collection of decoded smart contract information in conjunction with our open source work at Blockchain-ETL.
Example decoded smart contract from Arbitrum
These decoded contract information are a collaboration between Nansen and the open source community. Anyone is free to contribute via the Blockchain-ETL project.
These decoded smart contracts can be accessed via selecting the blockchain-etl project within the Nansen Query webapp, or from within the Google BigQuery console.
