What Is the Role of an ‘Oracle’ in the Liquidation Process?
An oracle provides reliable, real-time external price data to the decentralized exchange or smart contract. In liquidation, a decentralized exchange's smart contract relies on the oracle's price feed to determine if a position's collateral has fallen below the required threshold.
A robust, decentralized oracle is crucial to prevent manipulation of the reference price, which could lead to unfair or unnecessary liquidations.
