Cross-chain oracles act as bridges between decentralized networks and the real world, enabling communication between chains.
They provide data to multiple blockchains, supporting interoperability and use cases across ecosystems.
Leading cross-chain oracle providers include Chainlink CCIP, Band Protocol, API3, Witnet, and UMA, each with its own architecture and supported chains.
Use cases for cross-chain oracles span across DeFi, insurance, gaming, cross-chain governance, and stablecoin issuance, enhancing the reliability and composability of decentralized services.
