## Oracle-Based Price Feeds

Oracle-based price feeds are the external data sources that provide smart contracts with real-world price information for assets. Because blockchains cannot natively access off-chain data, oracles act as a bridge, delivering accurate and timely price data required for protocol operations.

In rebase tokens, these feeds are the heartbeat of the system, determining when and by how much the supply should be adjusted. Security is paramount, as a compromised or manipulated oracle feed can lead to catastrophic failure, such as an incorrect rebase or a total loss of value.

Many protocols use decentralized oracle networks to aggregate data from multiple sources, reducing the risk of a single point of failure. The latency and frequency of these updates are critical factors in the protocol's responsiveness to market volatility.

Maintaining trust in these feeds is a fundamental challenge in the development of reliable decentralized financial derivatives.
