Indexers play a crucial role in organizing and optimizing data retrieval across various systems. They serve as navigational guides, enhancing the efficiency of data access by creating structured indexes. Within the domain of databases and information management, indexers improve query performance by providing a roadmap to swiftly locate specific blockchain data entries.

In the context of blockchain and decentralized applications, indexers take on an even more pivotal role. Blockchains do not natively support complex queries as seen in traditional databases. This particular niche is where indexers come into play. They facilitate streamlined access to on-chain data, encompassing transaction histories, smart contract states, and event logs. In the dynamic and decentralized blockchain ecosystem, indexers ensure real-time data updates and seamless functionality for an array of applications and platforms.

There are a number of indexer solutions available, each offering unique advantages in terms of decentralization, ease of development, and performance. These solutions act as intermediaries, providing efficient assistance in the indexing process specifically for Peaq by enabling swift and effective data access and query functionality.


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 many ecosystems including Peaq, 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.

Running and Hosting your Peaq 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 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 Peaq from launch.
