 USDC/USDT mint, burn, and bridge flow rows derived from public ERC-20 transfer logs.
 
+## Current Scope
+
+- **Coverage:** Ethereum stablecoin mint/burn/bridge-style transfer rows from public ERC-20 logs.
+- **Best for:** Stablecoin supply-flow features, liquidity-regime monitoring, and crypto market context for forecasting/research agents.
+- **Cadence:** append-only partitions, normally refreshed by the Chainticks nightly publisher.
+- **Timestamps:** UTC ISO-8601 strings when available. Null timestamp fields mean the source event did not include a timestamp at collection time.

 Rows must have `source_kind` in `['on_chain_event']`. Chainticks does not publish venue REST/API resale data in this dataset.
 
+## Known Limitations
+
+Current rows emphasize large, easy-to-classify public transfer patterns. It is not a complete stablecoin supply audit.
+
 ## Agent Prompt Snippet
 
 Use this dataset as append-only market context. Read `LATEST_DATE.txt`, inspect `_schema.json`, then load the relevant Parquet partition. Treat timestamps as UTC and preserve `source_kind` in downstream analysis.
