Stacks Price Oracles

Introduction to DIA Oracles

DIA is a cross-chain oracle provider that sources granular market data from diverse exchanges, including CEXs and DEXs. Its data sourcing is thorough, enabling unparalleled transparency and customizability for resilient price feeds for 20,000+ assets. Its versatile data processing and delivery ensures adaptability and reliability for any decentralized application.

Usage of DIA Oracles on Stacks

dApps building on Stacks can utilize DIA oracles to obtain up-to-date asset price information. These deployed oracles are suitable for use in production environments. They come with a list of supported assets and settings. However, if dApps require a custom oracle with a different set of assets and configurations, they should contact DIA on Telegram.

Methodology: MAIR

The final price point for each asset is calculated by computing the assets' trade information across multiple DEXs and CEXs. This is done using a Moving Average with Interquartile Range (MAIR) methodology. Learn more about MAIR

Update frequency: 15-minute heartbeat

A consistent heartbeat refreshes all asset prices every 15 minutes.
