Stacks
dApps built on Stacks can leverage DIA oracles to access up-to-date asset price information.
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.

How to Access DIA Oracles?
You can query for assets like “STX/USD” or “stSTX/USD” in the get-value() read function. It returns two values:
