Contracts

All Props Oracle contracts live on Polygon mainnet. The oracle uses USDC.e as its bond token for UMA assertions, which is the same token Polymarket and most Polygon-deployed UMA products use.

Contract	Address	Purpose
EventRegistry	0x… (published at launch)	Maps canonical event IDs to single-slot assertion streams such as player stats, lines published, game outcomes, and voids. Bucketed MARKET_RESOLUTIONS claims do not write here.
UMA Optimistic Oracle V3	0x… (UMA deployment)	Stores assertion state and emits the AssertionMade log containing the market-resolution payload. Consumers read logs, not storage, for the payload itself.
USDC.e (bond token)	0x2791bca1f2de4661ed88a30c99a7a9449aa84174	Bond token for all Props Oracle assertions. Consumers do not interact with this directly.

The EventRegistry ABI is published in the repository and is intentionally minimal. For registry-backed streams, the main method is events(bytes32 canonicalEventId), which returns the RegisteredEvent struct containing assertion IDs and finalization flags. For MARKET_RESOLUTIONS, consumers should use UMA OOV3 assertion IDs discovered from logs or an indexer.

The UMA OOV3 address listed above is UMA's own canonical deployment on Polygon, not a Props Oracle contract. Consumers that want to subscribe to AssertionMade events or verify assertion state independently should use that address directly per UMA's own documentation.
