+# Perp Data
+
+Free, daily-updated perpetuals market data intended for quant research, backtesting, and market microstructure analysis.
+
+This repository is initialized for **chain-derived perp DEX data**, starting with Hyperliquid. The public dataset must only contain records whose provenance is public chain/archive state, not venue REST API resale. The first production feed will publish Hyperliquid funding, trades, and open interest as partitioned Parquet, under an explicit `hyperliquid_chain/` provider partition.
+
+## Status
+
+Initialized. Data publication starts after the Hetzner chain-derived `hyperliquid_chain` sink is live.
+
+## Planned Layout
+
+```text
+hyperliquid_chain/
+  funding/date=YYYY-MM-DD/part-0000.parquet
+  trades/date=YYYY-MM-DD/part-0000.parquet
+  open_interest/date=YYYY-MM-DD/part-0000.parquet
+_schema.json
+_manifest.json
+```
+
+## Quickstart
+
+```python
+import pandas as pd
+
+repo = "Chainticks/perp-data"
+url = f"https://huggingface.co/datasets/{repo}/resolve/main/hyperliquid_chain/funding/date=YYYY-MM-DD/part-0000.parquet"
+funding = pd.read_parquet(url)
+print(funding.head())
+```
+
+## Provenance
+
+Eligible public rows use one of these `source_kind` values:
+
+- `on_chain_event`
+- `chain_rpc`
+- `hypercore_s3`
+
+API-sourced internal research rows are intentionally excluded from this public dataset.
