Band Protocol serves as a cross-chain data oracle solution that bridges the gap between real-world data and on-chain applications. It does so by connecting APIs to smart-contracts, enabling the seamless exchange of information between on-chain and off-chain sources. This ability to provide trustworthy and verifiable real-world data to blockchains expands the horizons for developers, who can now incorporate a variety of real-world data into their decentralized applications (DApps), such as sports statistics, weather updates, random numbers, price feed data, and more.
