# Security and audits

## Oracles

Sturdy is oracle-agnostic and utilizes various oracles for different markets. The specific oracles used for a given market can be checked in the app. On Mode, all markets are secured by [RedStone](https://redstone.finance/) or [API3](https://api3.org/). The eBTC feed is provided by [eOracle](https://www.eoracle.io/).
