About DIA

DIA is Redefining Cross-Chain Oracles for Web3

What is DIA?

DIA is a blockchain oracle platform that fuels DeFi application data. Our mission is to enable a safe and efficient DeFi ecosystem by delivering price data for any asset on any chain: transparent, trustless, and verifiable.

DIA pioneers a new approach towards sourcing and delivering data. Instead of aggregating opaque third-party sources, DIA sources first party data directly from around 100 decentralized and centralized trading venues. This approach enables web3 projects to effortlessly power their applications while getting a full picture about where the raw data is sourced, how it is computed and delivered and enabling them to swiftly react to dynamically changing market situations.

Now a trusted resource for hundreds of dApps, DIA’s library features data for over 20,000 digital assets, RWAs, random number generation, contract state data for bridges and liquid staking protocols, advanced tooling to create and monitor data feeds and much more.


DIA’s oracles unlock a number of use-cases across EVM, WASM, and many more environments, powering countless transactions and securing many millions of dollars in TVL.

An all-in-one oracle suite

DIA acts as an orchestration layer for Web3 data and oracle needs. The platform assembles a range of best-in-class infrastructure modules across the data and oracle value chain from sourcing, storing, computing data to verification and delivery across more than 50 L1s and L2s.

First-Party Data Sourcing

DIA's data sourcing approach centres around first-party data, meaning that raw trade data is sourced directly from 100+ trading venues. This ensures that protocols always know what data they ingest.

Tailored to any Use Case

Every use case is different and every asset is different. DIA’s modular infrastructure stack enables dapps to define what is most suitable for them including the sources they use, the computation methodology, update frequency, delivery method and more.

Real-Time Monitoring and Adaptive Security

DIA offers advanced monitoring tools to ensure real-time tracking of oracles and data quality. DIA’s dynamic security logic enables quick reaction to unexpected changes in market conditions such as liquidity changes or deviating prices signals.


With the range of integrations that the ecosystem offers, DIA will play an important role in supplying Fantom developers with a highly-performant oracle service that is accurate and flexible. We’re extremely happy to be working with them.

Our top priority is to reduce frictions from developers’ on Polygon and onboarding oracle providers like DIA is a very crucial step for that. With DIA, developers do not have to set up their own data ingestion infrastructure and can start focusing on their end users’ needs from the get go.

It’s exciting to see DIA integrate on zkSync, their focus on price feeds for both long-tail assets as well as larger projects will enhance the diversity of the ecosystem and enable interesting new use cases in DeFi, NFT and their combination.
