Create trustless applications that interact with Web APIs

Leading blockchain oracle provider delivering fast, gas-efficient, cross-chain data feeds
RedStone solves the critical problem of getting reliable, real-time financial data onto blockchains for decentralized applications. Traditional oracle solutions are either too slow, too expensive, or can't support the diverse range of assets that institutional DeFi requires. RedStone's modular architecture allows protocols to access over 1,200+ price feeds, enabling everything from DeFi lending platforms to verify collateral values, to tokenized asset protocols requiring accurate pricing for real-world assets like treasuries and private credit. Our infrastructure serves as the official oracle for major institutional players, including BlackRock's BUIDL fund, making it simple for developers to integrate production-grade oracle solutions that scale with their needs.
