DIA was able to provide us with fast-updating DFYN price oracle which will find its use-case in many applications like borrowing/lending and prediction markets. We look forward to working with Dia for building new products for the long-tail and mid-tail of the crypto market.

DIA's data journey on Ethereum. From left to right: data sourcing from DEX and CEXs, computation in Oracle Platform (DIA), Price feed creation , and delivery on Ethereum via oracles

How does DIA ensure data accuracy and reliability?
DIA ensures accuracy through a multi-layered approach, starting with granular data collection from 90+ exchanges, followed by sophisticated data cleaning and outlier detection. By applying advanced pricing methodologies, customizable for any specific use case, DIA provides high-quality, resilient price feeds crucial for DeFi and NFTfi applications.
Can DIA create price feeds for tokens on any blockchain and integrate them into Ethereum-based DeFi apps?
Yes, DIA specializes in building price oracles for assets native to over 40 different chains. By scraping trade data directly from native exchanges and providing inter-ecosystem price feeds, DIA enables the listing and utility enhancement of these tokens in Ethereum DeFi and NFTfi protocols, facilitating a truly cross-chain experience.
How adaptable are DIA's data feeds for different DeFi application needs?
DIA's data feeds are highly customizable, with tailor-made feed construction (in terms of sources, filters, computation) as wel as update triggers (like request-based, time-based, and deviation-based options). This adaptability ensures that Ethereum developers can configure data refresh mechanisms that best suit the specific needs of their DeFi applications, whether it's for high-frequency trading platforms or low-liquidity asset tracking.
