Index Price Sources

Accurate and reliable index prices are crucial for our platform. We source index price data from multiple reputable sources via APIs to ensure robustness and reduce the risk of price manipulation and sustain availability. Accurate and up-to-date index prices are essential for Rails core services such as funding and trading metrics calculations.

To ensure reliability and availability, our system uses a multi-sourced cascading fallback approach for index pricing, detailed below:

Primary Source	Secondary Source	Tertiary Source
Coindesk Aggregate Index API - CCIX	CoinDesk Aggregate Index API - CCCAGG	Kraken's Ticker (Level 1) API
Our primary source of index prices.	Our secondary source, should our primary source become unavailable.	Our tertiary fall back source to maintain price availability if other sources fail.
