About Subsquid

Subsquid is a decentralized data lake and indexing network that provides scalable access to on-chain data for Web3 apps and AI systems. Developers can create custom APIs and subgraphs using its modular framework.

blockchain data indexing open-source API

Subsquid (SQD) is a cutting-edge decentralized data infrastructure designed to meet the high-performance needs of the modern AI and Web3 ecosystems. Described as the Data Lake for AI Agents, Subsquid provides permissionless access to petabytes of on-chain data, enabling real-time, scalable, and cost-efficient querying for developers, AI agents, and enterprises.

With the rise of autonomous systems, traditional data indexing solutions can no longer meet the demands of billions of AI agents operating at internet scale. Subsquid solves this by creating an open, emergent, and composable database network backed by the $SQD token. From Solana to Ethereum, Base to Polygon, the protocol indexes across multiple blockchains to serve as the foundational trustless data infrastructure of the AI era.

Subsquid was born out of a growing need for fast, decentralized, and developer-friendly access to blockchain data. As dApps and AI agents scale across chains, they require low-latency, high-throughput systems that don’t rely on centralized APIs. Subsquid emerged as a powerful response to this challenge by creating a decentralized indexing protocol that aggregates, stores, and serves blockchain data with high reliability.

At its core, Subsquid Network uses a modular architecture that separates data extraction, processing, and storage. Developers use the Squid SDK to define custom indexers and deploy them in a few lines of code. The protocol supports EVM chains, Solana, Polkadot/Substrate, Fuel, Starknet, and more, providing developers with an easy way to access multi-chain data without managing their own infrastructure.

Subsquid’s evolution from a niche Substrate indexer to a multi-chain powerhouse is evident in its mainnet launch on Arbitrum and support for Solana’s SVM. The platform has over 2480 workers and serves nearly 10 terabytes of data daily, with more than 250 million $SQD tokens staked. This level of decentralization ensures the network can meet the performance requirements of emerging AI use cases.

Through its Data Lake for AI Agents vision, Subsquid enables self-sovereign access to data — meaning that AI agents and applications can directly manage their data flow without human mediation. The protocol is already used by indexing applications for Arbitrum, Solana, Ethereum, Polygon, and more.

Competitors in this space include The Graph, Nansen, and Flipside Crypto, but Subsquid stands out through its unique blend of decentralization, speed, cost-efficiency, and AI compatibility. Its acquisition by Rezolve AI signals strong future alignment with AI-driven data infrastructure development.

Subsquid provides numerous benefits and features that position it as a leader in the decentralized data indexing and AI infrastructure space:

Subsquid FAQ

Subsquid is designed as a Data Lake for AI Agents, enabling autonomous systems to access multi-chain blockchain data at massive scale. It achieves real-time access through a decentralized network of nodes and workers that serve structured data directly to agents without relying on centralized APIs. By processing ~10TB of requests in 24 hours, Subsquid provides the infrastructure needed for billions of AI agents to independently manage their data streams.
The Squid SDK empowers developers to create custom blockchain indexers with minimal configuration. It supports multiple blockchain ecosystems including Ethereum, Solana, Polkadot, and Starknet. Developers can deploy light indexers tailored to specific smart contracts or event logs, giving AI agents and dApps instant access to verified, indexed data. The SDK integrates seamlessly into backends, making Subsquid’s SDK a vital tool for building AI-native Web3 applications.
$SQD is the native token of the Subsquid Network, used for staking, delegating, and data consumption. Anyone — human or AI — can use $SQD to request access to data indexed across supported blockchains. Token holders can run nodes, earn rewards, and contribute bandwidth or processing power. This decentralized incentive layer ensures that the network remains open, trustless, and scalable as more agents and developers rely on it for data delivery.
Yes, Subsquid offers the infrastructure for AI agents to autonomously access and analyze blockchain data in real time. Whether for DeFi trading bots, DAO governance agents, or RWA analysis tools, AI developers can build decision-making systems that leverage indexed, verified, and up-to-date on-chain data. With support from partners like Scade.pro and the AI Agent Grant Program, Subsquid is positioned as a foundational layer for AI-powered automation in Web3.
Subsquid allows indexing of smart contract events, transactions, balances, and custom application data across more than 30 blockchains. It supports EVM-compatible chains, Substrate-based chains, Solana’s SVM, and newer protocols like Fuel and Starknet. Whether a project needs ERC-20 transfers, NFT minting activity, DAO voting data, or custom DeFi metrics, Subsquid’s modular architecture ensures that any relevant on-chain data can be indexed and served efficiently.
