SubQuery is a developer toolkit designed to facilitate the construction of Web3 applications. It provides a complete API to organize and query data from Layer-1 and Layer-2 chains. Currently, it services a variety of blockchain projects including Ethereum, Polygon, BNB, NEAR, Polkadot, Avalanche, Algorand, Cosmos, Arbitrum, and Flare. The primary aim of SubQuery is to allow developers to focus on their core use case and front-end without the need to build a custom backend for data processing activities. In the future, the SubQuery Network intends to replicate this scalable and reliable solution in a completely decentralized manner.
Functionality and Services
Operating between layer-1 blockchains and decentralized apps (dApps), SubQuery is an open-source indexer that organizes and serves Web3 data over GraphQL. It aggregates and organizes data from various projects, offering well-structured data for developers to utilize for different projects. This is achieved by four tools offered to the developers: the SDK, SubQuery Projects, SubQuery Explorer, and the upcoming SubQuery Network.
The SDK, created through the platform’s involvement in the Web3 Grants Program, enables users to generate their own SubQuery Project and defines how the Indexer should traverse and aggregate their protocol. SubQuery Projects is an online managed service where users can publish their SubQuery Projects for public or private consumption. They are hosted on SubQuery’s hosting service. On the other hand, SubQuery Explorer is an online managed service that provides access to published, SubQuery Projects that are made by contributors in the community. Users can test queries in their browsers using the playground, or get GraphQL API endpoints for each project.
SubQuery is not only a current solution but also a future-oriented project. The SubQuery Network, which is still in development, aims to be the future of web3 infrastructure. It will facilitate an open web3 data revolution by allowing users to completely decentralize their infrastructure stack. The SubQuery Network will be the most open, performant, reliable, and scalable data service for dApps. This represents a significant step forward in the field of blockchain data management and offers a robust solution to potential data processing needs in Web3 projects.
SubQuery is a significant player in the Web3 infrastructure, providing a unique solution for data indexing and querying. By offering a suite of tools and services, it enables developers to focus on their core use case and front-end, reducing the need for complex and expensive data pre-processors. With its open-source nature and future plans for a decentralized network, SubQuery is poised to play a crucial role in the development and success of Web3 applications.
