О UMA

UMA is an optimistic oracle that uses economic guarantees to secure markets. Unlike mechanically restrictive price feed oracles, UMA's oracle is able to serve any arbitrary data on-chain. It can be used for a variety of purposes, such as a cross-chain bridge, insurance, custom derivatives, and prediction markets.The UMA Protocol also provides various smart contract templates, which are automatically secured by its optimistic oracle. These include templates and integrations for creating synthetic tokens, prediction markets, "KPI options", and structured financial products.
