Upon successful retrieval, the Stork oracle price is compared against the Pyth oracle price. In the event that the stork price and Pyth price are not similar to a certain threshold, which varies per asset, the system will stop all processes that require an accurate price. The systems will stay offline until the prices are within the threshold. In such an event, the Stork price is used. For collateral assets, an accurate price is less critical, outside the 8am price fixing. In this case, the price used depends on if the oracle provider supports a price for that asset, and a manual check is conducted by the Rysk team at price fixing during a 5-minute smart contract enforced dispute period. * **Stork:** [https://stork.network](https://www.stork.network) * **Pyth:** * Pendle: the Pendle API is used directly to price pendle assets.
