DIA Data

Oracles have been black boxes for too long. Billions in DeFi TVL rely on oracles delivering opaque and unverifiable data. DIA is built to address this issue.

DIA Oracles Overview

**DIA Lumina is a new oracle architecture with an ETH layer-2 at its core**.

How it Works

Explore the chains where Lumina oracles are live and start integrating them.

Integrated Chains

DIA token price feeds provide smart contracts with real-time price information of cryptocurrencies, transparently sourced from high-volume DEXs and CEXs.

Token Price Feeds

Seamlessly define, deploy, and manage price oracles tailored to your specific needs.

Oracle Builder (Beta)

Stake DIA

DIA offers highly customizable oracles that are individually tailored to each dApp’s needs. Each oracle can be customized in several ways, ensuring that the data and oracle remain robust and resilient to market volatily.

The table outlines the differences between Nexus and Lumina, which are both oracle solutions supported by DIA:

Nexus vs. Lumina

This page provides a comprehensive list of all the blockchain networks where DIA Nexus is accessible.

DIA xMarket feeds provide smart contracts **real-time price information of 3,000+ cryptocurrencies**, transparently sourced from 80+ trusted, high-volume DEXs and CEXs.

DIA xReal is designed for Real-World Asset (RWA) applications, bringing hundreds of data feeds for stocks, commodities, FX rates, and more on-chain.

RWA Price Feeds

**DIA xRandom provides smart contracts with unpredictable random numbers**.

Randomness

DIA xFair is a new oracle product that provides DeFi protocols with **transparent and collateral-proofed price feeds for illiquid assets** such as LSTs, computed through on-chain collateral ratio checks.

Fair-value Feeds

The `DiaAssetSpecificCallingConvention` contract is compatible with `AggregatorV3Interface`, allowing developers to read price data from a DIA oracle contract deployed for each asset by calling `latestRoundData()` and returning the latest available price of that specific asset.

Migrate to DIA

Oracles require a constant stream of updates, thus gas costs reimbursement for updates is needed. To achieve this, all oracles deployed by DIA have a dedicated wallet which calls oracle contracts for updates. This is referred to as the "gas wallet".

Fund the Oracle

DIA offers highly customizable oracles that are individually tailored to each dApp’s needs. Each oracle can be customized in several ways, including but not limited to price feeds, data sources, data cleaning filters, pricing methodologies, and oracle update mechanisms. This ensures that the data and oracle remain robust and resilient to the market conditions and provide a global market as well as a specific individual or cross-chain market prices.
