DIA

Overview

DIA is a cross-chain oracle platform for Web3. It serves as an ecosystem for transparent financial data within a smart contract environment dedicated to finance. DIA's mission is to foster a collaborative environment among data analysts, providers, and consumers. Essentially, DIA offers a trustworthy and verifiable conduit linking external data from diverse origins to on-chain smart contracts, facilitating the creation of a myriad of financial decentralized applications. DIA is architected as a hybrid framework, integrating off-chain mechanisms for the storage and manipulation of extensive datasets, with on-chain elements that supply data to financial smart contracts.

DIA's Oracle

Here is an overview of the deployed oracle contracts on each supported chain.

DIA Development Oracle contracts are smart contracts that offer a selected range of asset prices for live testing on our Mainnet and Testnet. These contracts are regularly updated and replaced, not maintained indefinitely.

DIA Development Oracle contracts are not meant to be integrated into a dApp. DIA creates specific contracts for dApps. To request a dedicated oracle, please contact the team on their website Discord or the DIA DAO Forum.
