Following our recent deployment on Base Sepolia, DIA is bringing DIA Lumina to the Arbitrum testnet—another step forward on the Road to Mainnet. Each testnet deployment marks progress toward our goal of launching a fully decentralized, trustless oracle network on mainnet.
Advancing Fully On-Chain Oracle Infrastructure
Traditional oracles often depend on off-chain computation, introducing trust assumptions and limiting transparency. DIA Lumina changes this by ensuring that data sourcing, processing, and aggregation happen entirely on-chain. By eliminating off-chain intermediaries, DIA Lumina offers developers a fully verifiable and trustless oracle infrastructure—an essential step toward a robust and scalable mainnet deployment.
True On-Chain Oracles for Arbitrum
With the Arbitrum testnet deployment, developers can now experiment with DIA Lumina’s on-chain price feeds . Both pull-based and push-based oracle mechanisms are available, giving builders the flexibility to integrate transparent, decentralized data feeds seamlessly. This testnet phase is crucial in refining our technology and gathering feedback to optimize DIA Lumina before its mainnet launch.

Expanding the On-Chain Oracle Ecosystem
DIA Lumina’s deployment on Arbitrum represents another milestone on the Road to Mainnet. As we continue expanding across multiple ecosystems, each testnet integration brings us closer to delivering the most transparent and verifiable data infrastructure for Web3 applications.
