{% hint style="info" %}
**Understanding the vulnerabilities:** In the ever-evolving world of decentralized finance (DeFi), oracles have emerged as a cornerstone, bridging the gap between off-chain data and on-chain smart contracts. As blockchain systems are deterministic and cannot access data outside their network, oracles play the critical role of delivering external data (such as price feeds) to these systems. However, as with any innovative technology, oracles come with their own set of vulnerabilities. The complex interplay between oracles and the underlying blockchain structure makes for a fertile ground for potential pitfalls. By understanding these vulnerabilities, we can ensure a more secure and reliable decentralized future.
