## Oracle Failure Risks

Oracle failure risks refer to the vulnerabilities inherent in decentralized finance protocols that rely on external data feeds to trigger smart contract executions. These systems depend on oracles to bridge real-world asset prices to the blockchain.

If the oracle provides inaccurate, delayed, or manipulated data, the protocol may execute incorrect liquidations, allow under-collateralized borrowing, or fail to process trades accurately. This risk is often amplified by low liquidity on the source exchanges the oracle monitors.

Furthermore, centralized oracle nodes can become single points of failure if they are compromised or go offline. Sophisticated attackers may manipulate thin order books on centralized exchanges to trigger specific price feeds that exploit a protocol.

Mitigation strategies involve using decentralized oracle networks that aggregate data from multiple independent sources. Reliance on a single data point is considered a critical security flaw in high-leverage derivative environments.
