SubQuery

SubQuery is a 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 decentralized applications more efficiently. SubQuery supports 100+ ecosystems including Linea, Ethereum, Polygon, Polkadot, Algorand, NEAR, and Avalanche.

One of SubQuery's key features is that it aggregates data across multiple blockchains within a single project. This allows you to create feature-rich dashboard analytics and multi-chain block scanners.

Other features include multiple RPC endpoint configurations, multi-worker capabilities and a configurable caching architecture.

Running and hosting Linea SubQuery APIs​

SubQuery is open-source, meaning you can run it in three ways:

  • Locally on your own computer (or a cloud provider of your choosing). View the instructions for running SubQuery locally.
  • Publish 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. A free tier is also available. Learn more..
  • Publish to the decentralized SubQuery Network, an open 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 Linea from launch.
