## Price Oracle Feed

A Price Oracle Feed is a service that provides external data to a smart contract, specifically delivering real-time asset prices from off-chain sources to on-chain environments. Because blockchains are isolated networks, they cannot natively access external information, such as the price of a token on a centralized exchange.

The oracle acts as a bridge, fetching data from multiple sources, aggregating it, and pushing it to the blockchain. This process is critical for decentralized finance applications, as these protocols rely on accurate pricing to trigger liquidations, execute trades, and calculate collateral values.

If an oracle feed is manipulated or becomes stale, it can lead to catastrophic financial losses within a protocol. Therefore, many systems use decentralized oracle networks to ensure data integrity and prevent single points of failure.
