SubQuery#

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

Another of SubQuery’s competitive advantages is the ability to aggregate data not only within a chain but across multiple blockchains all within a single project. This allows the creation of feature-rich dashboard analytics and multi-chain block scanners.

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

Running and Hosting your Concordium 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 SubQuery will host your SubQuery project in production-ready services for mission critical data with zero-downtime blue/green deployments. There is even a generous free tier. Find out how.

  • You can publish it to the decentralized 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 incentivized and verifiable way and supports Concordium from launch.
