Open-source tools that turn raw blockchain data into clean, documented tables in a warehouse you own, and the open datasets they produce. Built in Cape Town.
Raw blockchain data to clean dimensional tables in your own warehouse, from one command. Ethereum, Base, Bitcoin and Solana into DuckDB or Postgres, as a tested dbt star schema of transfers, fees, wallets, tokens and dates. You bring the RPC, or try it on free public endpoints; nothing passes through us.
