To prevent flash loan-related price oracle attacks, it is strongly recommended that DeFi protocols utilize Chainlink Price Feeds as their source of validated market data. Chainlink’s decentralized oracle network aggregates price data from multiple independent data sources, providing full market coverage and mitigating the risk of price manipulation. Since flash loans only exist within the timeframe of a single on-chain transaction, any manipulation that occurs is reverted by the end of the transaction, making Chainlink Price Feeds immune to such attacks.
