Darwinia’s Network Data is Now Available for Free on SubQuery

3 min readJun 2, 2021


We are pleased to announce that SubQuery and Darwinia Network have formed a strategic partnership.

Darwinia recently released two new SubQuery projects, one for the mainnet and the other for Crab, the canary network of Darwinia. By exposing the data on SubQuery, Darwinia is opening the door for the application ecosystem to build more engaging applications on this free datasource.

“Using SubQuery to query Darwinia’s on-chain data has become very simple and flexible. SubQuery regards blockchain data as a graph, and leverages the extensibility of GraphQL to introduce additional functionality. We believe that in the future, the data interface on the substrate chain will mainly use GraphQL, SubQuery is making this a reality.” — Darwinia

Details of Cooperation

SubQuery’s service helps Darwinia unlock chain data and to make it more accessible for their application ecosystem. Applications, for example a NFT marketplace, could use the data from Darwnia’s SubQuery to show auction statistics, and could even extend the Darwinia SubQuery project to aggregate and transform data to provide even more unique data insights.

Thanks to SubQuery, we can easily query the transfer times of each account on the chain. For example, we can get the three account with the most sent and receive transactions through the query below:

Darwinia is using SubQuery Projects to manage their own project and make updates as required. The indexing and query services for this service is completely managed by SubQuery and provided to the Polkadot community for free in SubQuery’s Explorer. You can play around with the Darwinia SubQuery dataset here (and Darwinia’s Crab here) using the Explorer without implementing any code. As you wish, obtaining the records of a specific account would become very simple.

The query indicates that we need to get the latest 20 records whether is sending or receiving with the address 2pKfuFCEAw6acaYwu2cPEcD7mrnTW7dDrLgdMuSkk8BrU4q2.

About SubQuery

SubQuery is a data aggregation layer that will operate between the layer-1 blockchains (Darwinia) and DApps. The solution aggregates and organises data from Darwinia and other blockchains, serving up well-structured data for their dApp and for other developers to use in a wide array of projects. This service allows DApp developers to focus on their core use case and front-end, without needing to waste time on building a custom backend for data processing.
