## Stork Oracle

RISEx uses [Stork](https://stork.network) for price feeds. Stork is a high-frequency oracle network designed for DeFi applications requiring realtime pricing.

***

## Update Frequency

Prices are updated **onchain once per second**.

This frequency ensures:

* Accurate mark prices for margin calculations
* Fair liquidation triggers
* Reliable funding rate computations

***

## How It Works

Stork aggregates prices from multiple sources and publishes them onchain with cryptographic attestations. The oracle network is designed for low-latency delivery, matching the performance requirements of realtime trading.
