Oracles

zkLend uses the industry standard decentralized oracle Chainlink as its primary oracle which provides highly secure and reliable, tamper-resistant data feeds. By aggregating data from multiple high-quality sources and utilizing its Decentralized Data Model, Chainlink ensures accurate price updates that meet the protocol’s stringent requirements for security and transparency. Chainlink’s feeds have been adopted by leading DeFi platforms like Aave and Synthetix and now play a key role in zkLend’s ecosystem, enhancing the robustness and scalability of our platform as we continue to serve the Starknet community.

zkLend currently consumes Chainlink price feeds for the following assets: ETH, wBTC, wstETH, STRK, DAI, USDC, and USDT.

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.
