Our oracle provider Pragma, leverages state-of-the-art zero-knowledge cryptography to deliver decentralized and transparent price feeds on chain. Pragma partners with the biggest market makers and the most liquid exchanges who sign and timestamp their own high-quality, robust data and send it directly on-chain. Their feeds live on Starknet mainnet and Goerli, where they are powering the next generation of ambitious protocols such as zkLend, CurveZero, FujiDAO, and more. Their code has been audited by leading security researchers at Zellic and they have more audits coming up soon.
