SubQuery Indexer

note

This article has been kindly provided by the SubQuery team.

Intro​

SubQuery is a leading blockchain data indexer that provides developers with fast, flexible, universal, open source and decentralised APIs for web3 projects. SubQuery SDK allows developers to get rich indexed data and build intuitive and immersive decentralised applications in a faster and more efficient way. SubQuery supports 100+ ecosystems including Vara, Polkadot, Cosmos, Ethereum, Polygon, Algorand, NEAR, and Avalanche.

Another Subquery's competitive edge lies in the capacity to consolidate data, not just within a single blockchain but across multiple blockchains within a unified project. This facilitates the development of comprehensive dashboard analytics, cross-chain block scanners, or initiatives aimed at indexing XCM messages across parachains.

Other advantages include superior performance with multiple RPC endpoint configurations, multi-worker capabilities and a configurable caching architecture. To find out more, visit our documentation.

Running and Hosting your Vara SubQuery APIs​

SubQuery is open-source, meaning you have the freedom to run it in the following three ways:

  • Locally on your own computer (or a cloud provider of your choosing), view the instructions on how to run SubQuery Locally.
  • You can publish it to SubQuery's enterprise-level Managed Service, where we'll host your SubQuery project in production ready services for mission critical data with zero-downtime blue/green deployments. There even is a generous free tier. Find out how.
  • You can publish it to the decentralised SubQuery Network, the most open, performant, reliable, and scalable data service for dApp developers. The SubQuery Network indexes and services data to the global community in an incentivised and verifiable way and supports Vara from launch.
