Early-block NFTs approvals from 286m decoded Ethereum events

We decoded 286 million raw Ethereum events from Sepolia's early blocks (genesis through ~3M) into clean, query-ready Parquet files. The focus is on ERC-20/ERC-721 transfers and approvals — the kind of data you'd need for ML training, compliance analysis, or building indexers. Getting historical decoded event data usually means running your own archive node or paying per-RPC-call. We had the infrastructure from another project, so we packaged the output as a flat file.
This is the 2nd launch from ∂₀ Sepolia Historical Archive. View more
