Smart contracts can only act on on‑chain data, but real‑world events happen off‑chain. Oracles bridge that gap by delivering verified external information—prices, weather, election results—to the blockchain. In DeFi, oracles enable stablecoins, futures, and lending protocols to stay accurate and secure. Without reliable oracles, automated finance would be blind, exposing users to mispricing and fraud.
