# UMA Oracle

**UMA (Universal Market Access)** is the oracle protocol Polymarket uses to resolve markets on its international platform. 

Here's how it works: 

When a market is ready to be resolved, users can propose an outcome through the UMA oracle by posting a **$750 bond**. If the outcome goes **unchallenged**, the market resolves to that outcome and the proposer earns their bond back plus a **$2 reward**. If it's **disputed**, it goes to a vote, where oracle participants decide how the market should resolve. If the proposer **loses**, they **lose their bond**.
