cryo is a Rust-based CLI tool (also available as a Python package) that extracts Ethereum/EVM blockchain data into parquet, csv, , or Python dataframes. It offers flexible options for filtering, formatting, and controlling extraction from an RPC node.
Use cases
- extract all ethereum logs between two block ranges to parquet
- download blocks transactions and traces as csv files
- pull all USDC contract events into a python dataframe
- export blockchain data to for analysis
- backfill missing datasets like blocks txs and traces from an archive node
- extract only specific columns from blockchain datasets
When to choose
- you need bulk EVM blockchain data in parquet/csv//dataframe formats
- you run your own node or archive node and want fast local extraction
- you want a simple CLI or Python API for blockchain ETL
When to avoid
- you only have a third-party RPC provider without careful rate limiting, since default settings can overwhelm it
- you need non-EVM blockchains
- you need a fully stable production tool, as it is an early work-in-progress
