Hello Astar: DIA First Oracle to Integrate with the Polkadot Parachain

DIA is the first oracle provider to integrate its oracle infrastructure with the Astar Network, running in the Polkadot Relaychain. The oracle deployment will facilitate DeFi applications on Astar to easily connect to the outside world data.

Update April 18th, 2022: WASM-compatible oracles are live on Astar. Scroll down to learn more about the integration and test a demo oracle on Shibuya.

Introducing Astar Network

Astar Network, previously known as Plasm, is a dApp hub on Polkadot that supports Ethereum, WebAssembly, and layer 2 solutions like ZK Rollups. Astar aims to be a multi-chain smart contract platform that will support multiple blockchains and virtual machines. As the Polkadot Relay Chain doesn’t support smart contracts, Astar is working to provide a solution for all developers by parachain where EVM and WebAssembly smart contracts can co-exist and communicate with each other.

Astar Network won the 3rd Polkadot parachain auction on December 2, 2021, with block number #7927110 and onboarded to the Polkadot Relay Chain on December 18 2021.

Deploying the First Oracle on Astar

We are delighted to announce that DIA has integrated its decentralised oracle infrastructure with the Astar Network, running in the Polkadot Relaychain. The oracle deployment will facilitate DeFi applications on Astar to easily connect to the outside world data via DIA’s trusted oracles. As this is the first oracle integration on the network, DIA will enable the Astar ecosystem to access reliable financial data.

Maarten Henskens, VP of Growth of Astar Network comments:

“DIA was the first oracle on our canary network Shiden and now the first oracle on our mainnet, Astar. DIA gave great support to us and projects that are building in our ecosystem and looking for a trusted oracle. At Astar ecosystem, we offer our developers the best dApp platform inside the Polkadot ecosystem with the best tooling and integrations. DIA is one of those integrations we promote highly amongst our developer community.”

Thanks to Astar’s Ethereum and WebAssembly compatibility, DeFi applications can seamlessly be deployed on Astar’s parachain, where DIA will be able to feed them with accurate and transparent market data. DIA’s price feed oracles will fuel a range of use cases, such as lending and borrowing protocols, stablecoins, staking rewards and many more.

To build the data feeds, DIA simultaneously aggregates price data at a very trade level directly from centralised and decentralised exchanges. This decentralised approach to data sourcing provides highly accurate price feeds on-chain and reduces exposure to data manipulation.

Astar Network DIA Demo Oracle

Note: DIA Demo Oracle contracts are not intended to be integrated into dApps. DIA deploys dedicated contracts for dApps, please request a dedicated oracle. Learn more about DIA demo oracles on the DIA Documentation.

WASM Oracles live on Astar

Update April 18th, 2022

DIA has expanded its oracle capabilities on the substrate ecosystem by making its oracle infrastructure compatible with the WASM development language. The dApps on Astar, built on the WASM development toolkit language, can now access transparent and reliable price feeds with DIA oracles. Find all the details in the DIA Github repository.
