About the Project

SubQuery is a data aggregation layer that operates between the layer-1 blockchains (Moonriver and Polkadot) and DApps. This service unlocks blockchain data and transforms it to a queryable state so that it can be used in intuitive applications. It 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.

About the Integration

SubQuery, the leading data indexing solution in Polkadot, has announced support of its services with Moonbeam’s and Moonriver’s Ethereum Virtual Machine (EVM). This allows Polkadot and Ethereum developers to seamlessly integrate both Substrate and EVM data into one place and query this single datasource using GraphQL.

Currently, there is no open-source tool which allows developers to flexibly collect and query data across both Ethereum and Polkadot/Kusama. This limitation can cause dApps solutions within Moonriver to be siloed into the smart contract layer and thereby limit their potential to consumers across both thriving networks. This integratoin with Moonbeam brings a complete and unified data indexing solution for all blockchain data within Moonriver and will greatly benefit Moonriver’s growing application ecosystem.

With SubQuery’s innovation, one tool can now query and filter EVM logs and transactions in addition to Substrate data sources. SubQuery introduces more advanced filters than other indexers, allowing filtering of non-contract transactions, transaction senders, contracts and indexed log arguments, so developers can build a wide variety of projects that cater to their specific data needs.
