UMA is a decentralised finance protocol on Ethereum that provides an optimistic oracle for reporting data to smart contracts and tooling for creating synthetic assets.
Semantic Classification

- UMA, short for Universal Market Access, operates an optimistic oracle in which proposed answers are accepted unless disputed within a challenge window. Disputes are resolved by token holder voting, with economic incentives discouraging false reports.
- The oracle is used by other protocols to bring off-chain data and arbitrary truth claims on chain, and UMA also provides contracts for minting synthetic tokens whose value tracks a reference price.
