Polymarket Indexers & Oracles
Indexers and oracles form the foundational infrastructure of Polymarket. Indexers (subgraphs, custom data pipelines) make historical and real-time on-chain data efficiently queryable. Oracles (primarily UMA's Optimistic Oracle) resolve markets by bringing real-world information on-chain. These tools are essential for developers building deeply integrated Polymarket applications.

Frequently Asked Questions
What oracle does Polymarket use for resolution?▼
Polymarket uses UMA's Optimistic Oracle (OO) for market resolution. The OO uses an optimistic mechanism where proposed resolutions are accepted unless disputed within a challenge window. UMA token holders vote to resolve disputes.
What is a Polymarket subgraph?▼
A subgraph is a data indexing service (typically built on The Graph protocol) that indexes Polymarket smart contract events into a queryable GraphQL API. Subgraphs make it much faster to access historical trade data than querying the blockchain directly.
Do I need to understand oracles and indexers to build on Polymarket?▼
For most applications (trading bots, analytics dashboards, portfolio trackers), you do not need to interact with oracles or indexers directly — the Polymarket REST APIs abstract this. Oracles and indexers matter if you are building protocol-level infrastructure or custom data pipelines.
