What is Oracle Risk?
Oracle risk refers to vulnerabilities arising from blockchain oracles—services that feed external data to smart contracts. If oracle data is wrong or manipulated, protocols may execute incorrectly.
Types of Oracle Attacks
- Price manipulation: Flash loan attacks distorting prices
- Stale data: Outdated prices during high volatility
- Oracle downtime: Data feeds becoming unavailable
- Centralization risk: Single oracle point of failure
Mitigating Oracle Risk
- Use decentralized oracle networks (Chainlink, Pyth)
- Implement TWAP (time-weighted average prices)
- Add circuit breakers for extreme price movements
- Use multiple oracle sources
