Telonex — Historical Polymarket data for backtesting and research

What is Telonex?

Telonex is a historical data service. Its channels include tick-level trades and book updates, top-of-book quotes, daily snapshots, on-chain activity and crypto reference prices. Coverage start dates vary by venue and channel; the long on-chain history should not be mistaken for equally long order-book capture.

Who it is for

  • Quants replaying market microstructure
  • Researchers studying wallet flow and execution
  • Developers building historical datasets in DuckDB, Polars or pandas

    What to check

    • Daily historical files are not a live execution feed.

    Our take on Telonex

    Daily files, event-level books and distinct data channels support reproducible historical research. Venue inception dates and personal/commercial licensing must match the intended analysis and reuse.
