Smart contracts are only as good as the data they use. Oracles bridge that gap, feeding real‑world prices, events, and randomness into chains. In DeFi, price oracles keep lending rates accurate, while event oracles trigger automated actions. Chainlink, Band Protocol, and Tellor illustrate how decentralized oracles reduce single‑point failures, yet they also introduce new attack surfaces that users must monitor. Dive into oracle design to understand DeFi resilience.
