# Oracles

Index and collateral prices for all markets are derived from trusted data sources.

Prices are retrieved via our oracle aggregator, which collects data from various providers. Supported external oracles currently include [Stork](https://www.stork.network/), [SEDA](https://seda.xyz/), [Pyth](https://www.pyth.network/price-feeds) and [Switchboard](https://switchboard.xyz/).
