What Is the UMA Oracle?

UMA (Universal Market Access) is a decentralized oracle that resolves subjective real-world outcomes on-chain: sports, elections, awards, and anything requiring human judgment.

How It Works

  1. Proposal: anyone stakes UMA tokens and submits a result claim
  2. Dispute window: 24 to 48 hours to challenge
  3. Vote: UMA holders decide if disputed
  4. Settlement: final result sent to smart contract for automatic execution

Why UMA?

  • Decentralized: no single entity controls settlement
  • Economic incentives ensure honest reporting
  • Handles any real-world event type
  • Fully auditable on-chain
