# Polymarket indexers and on-chain data tools

Use indexed blockchain activity without building the whole indexing pipeline yourself. Tools turn contract events into datasets, queries or streams for prediction-market applications.

How to choose on-chain data

## Choose the data workflow

-   Query decoded trades and market events.
-   Track positions and participant activity.
-   Deliver indexed changes to an application or warehouse.

## Check what the source represents

Compare contract coverage, response schema, historical reach and delivery method. An on-chain trade stream describes different data from the exchange’s resting order book. Select the source needed by your application rather than substituting one for the other.
