Beyond Basic Infrastructure: The SubQuery Data Layer for Web3
In blockchain development, the greatest bottleneck isn't creativity—it's data access. Developers spend excessive resources building and maintaining custom backend systems to query on-chain information. SubQuery, co-founded by Ian He and James Bailey, directly solves this by providing a decentralized, open-source data layer. It functions as a unified marketplace for indexed data and reliable RPC access, abstracting infrastructure complexity so teams can concentrate on core application logic and user experience.
How SubQuery's Decentralized Network Operates
The SubQuery Network is not a single service but a coordinated ecosystem. It connects three key participants: Consumers (developers), Indexers, and Delegators. Indexers operate nodes, using the open-source SubQuery SDK to transform raw blockchain data from supported chains—like Ethereum, Polkadot, or Cosmos—into rich, queryable GraphQL APIs. This process, known as blockchain data indexing, turns unstructured on-chain logs into structured datasets ready for DeFi dashboards, NFT explorers, or complex analytics tools.
The Technical Edge: Indexer SDK & Multi-Chain Support
The SubQuery Indexer SDK is a foundational tool for data engineers. It allows for the creation of custom data extraction and transformation scripts, defining exactly which events, extrinsics, or smart contract calls to capture. This granular control is crucial for applications requiring specific data sets, such as tracking liquidity pool metrics across multiple decentralized exchanges or aggregating cross-chain user activity. By supporting nearly 300 blockchain ecosystems, including EVM chains (Base, Arbitrum) and Substrate-based networks, SubQuery ensures developers aren't locked into a single protocol.
Decentralized RPC: Mitigating Single Points of Failure
Beyond data indexing, SubQuery addresses another critical pain point: Remote Procedure Call (RPC) reliability. A decentralized application's performance hinges on its connection to blockchain nodes. SubQuery's decentralized RPC service distributes requests across a global network of independent node operators. This load balancing enhances uptime, reduces latency, and eliminates the risk associated with relying on a single centralized RPC provider, which can be a target for censorship or a bottleneck during network congestion.
The SQT Token: Fueling Network Incentives and Governance
The SubQuery Token ($SQT) is the utility token at the heart of the network's economic security and governance. Its primary functions are:
Payment for Services: Developers use $SQT to pay Indexers for queries and RPC access.
Indexer Incentives: Indexers earn $SQT rewards for providing accurate, high-uptime data services. They must stake $SQT as collateral, which can be slashed for malicious behavior, aligning economic incentives with data integrity.
Community Governance: $SQT holders can participate in protocol upgrade votes and parameter changes, fostering a decentralized, community-led evolution. The strategic allocation of the 10 billion total supply focuses on long-term network growth and operator support.
Building for the Future: AI Framework and Strategic Vision
Looking ahead, SubQuery's AI App Framework provides a blueprint for building machine learning applications in a decentralized context. This allows for the creation of AI agents or analytical models that can process indexed on-chain data in a trust-minimized environment, opening doors for predictive analytics, automated risk assessment, and intelligent dApp interactions.

For developers, the question is no longer whether to build on multi-chain infrastructure, but how to do it efficiently. By providing a robust, decentralized data layer, SubQuery removes a significant barrier, allowing innovation to scale.
