∂₀ Sepolia Historical Archive – Decoded ERC-20/ERC-721 events from 286M Sepolia blocks

Summary: This archive provides 286 million decoded Ethereum events from Sepolia’s early blocks (genesis to ~3M) in query-ready Parquet files, focusing on ERC-20 and ERC-721 transfers and approvals for ML, compliance, or indexing.

What it does

It converts raw Ethereum event data into clean, flat Parquet files covering transfers and approvals, enabling efficient querying without running an archive node or paying per RPC call.

Who it's for

Developers and analysts needing historical decoded Sepolia event data for machine learning, compliance analysis, or building blockchain indexers.

Why it matters

It eliminates the need to maintain archive nodes or costly RPC queries by providing a ready-to-use dataset of early Sepolia blockchain events.
