  • Token launched: 2024 via CoinList public sale
  • Key tools: Squid SDK and Subsquid Cloud

Introduction

Subsquid is a decentralized data infrastructure protocol built for Web3 developers. It gives applications fast, permissionless access to on-chain data without relying on centralized intermediaries.

At its core, Subsquid operates as a distributed data lake and query engine, storing and serving blockchain data across a network of independent worker nodes. Developers can query this data efficiently, powering everything from DeFi dashboards to NFT explorers.

History & Background

Subsquid was founded in 2021 by Dmitry Zhelezov and Marcel Fohrmann with a mission to solve one of Web3's persistent infrastructure problems: reliable and scalable access to blockchain data.

The project raised initial funding through a seed round and later conducted a public token sale on CoinList. The SQD token officially launched in 2024, marking the transition to a fully token-powered decentralized network.

How Subsquid Works

Subsquid's architecture revolves around a decentralized data lake — a peer-to-peer network of worker nodes that store and serve raw blockchain data. This replaces centralized APIs with an open, distributed alternative.

The Squid SDK allows developers to build custom indexers and APIs on top of this data layer. For teams that prefer a managed experience, Subsquid Cloud offers a Platform-as-a-Service deployment option requiring no custom infrastructure setup.

The network uses zero-knowledge proof technology to verify data integrity, ensuring security without sacrificing performance.

Tokenomics

The SQD token is the economic engine of the Subsquid Network. Its utility spans several functions:

  • Staking: Node operators stake SQD to participate in the network and earn rewards for providing data services.
  • Delegation: Token holders can delegate SQD to node operators and share in their rewards.
  • Data access: Users lock SQD to increase their data bandwidth and access premium datasets.
  • Governance: SQD holders vote on protocol upgrades and future direction.

The token's economic design ties its value directly to real network demand, with enterprise data consumption driving a 'Revenue Pools' model introduced in late 2025.

Ecosystem & Use Cases

Subsquid serves a broad range of developer use cases across the Web3 space:

  • DApp development: Fast indexing of smart contract events for decentralized applications.
  • Analytics platforms: Historical and real-time data pipelines for blockchain analytics.
  • DeFi and NFT tooling: Custom APIs for tracking liquidity, trades, and NFT ownership.
  • Enterprise integrations: Connectors to tools like Kafka and Snowflake for large-scale data workflows.

The network spans over 200 blockchains including Ethereum, Polkadot, Solana, and other EVM-compatible chains.

Team, Governance & Community

Subsquid was co-founded by Dmitry Zhelezov and Marcel Fohrmann, who bring backgrounds in blockchain technology and data infrastructure. The team has grown to support a multi-chain protocol and a global developer community.

Governance is managed through SQD token voting, allowing the community to influence key protocol decisions. The project maintains active communities on Telegram and Twitter.

Advantages

  • Broad network coverage — supports 200+ blockchains in a single unified interface.
  • Modular and customizable — developers can tailor data pipelines to specific project needs.
  • Decentralized and permissionless — no centralized gatekeepers controlling data access.
  • Real-time indexing — enables low-latency access to the latest on-chain data.
  • Developer-friendly tooling — Squid SDK and Subsquid Cloud lower the barrier to entry.

Risks & Challenges

  • Competitive landscape — established players like The Graph offer similar indexing services with larger existing adoption.
  • Node operator dependency — network performance relies on sufficient worker node participation.
  • Token adoption — widespread SQD utility depends on growing developer and enterprise demand.
  • Complexity — building custom indexers can require significant technical expertise.

Long-Term Vision

Subsquid aims to become the foundational data infrastructure layer for Web3. As decentralized applications multiply across hundreds of blockchains, the demand for reliable, open, and scalable data access will only grow.

The protocol's roadmap focuses on expanding chain coverage, deepening enterprise integrations, and strengthening the token-incentive model to create a self-sustaining, permissionless data economy.

Frequently Asked Questions

Subsquid is a decentralized data lake and query engine that gives Web3 developers fast, permissionless access to blockchain data across more than 200 networks. It replaces centralized data APIs with a distributed network of worker nodes.

SQD is the native utility token of the Subsquid Network. It is used for staking by node operators, delegating to earn rewards, accessing data bandwidth, and participating in protocol governance.

Subsquid supports over 200 blockchains, including Ethereum, Polkadot, Solana, and a wide range of EVM-compatible and Substrate-based networks. This broad coverage makes it one of the most versatile blockchain data protocols available.

Subsquid uses a modular, decentralized data lake architecture that allows for greater customization and broader chain coverage compared to The Graph. Its real-time indexing and ZK-proof-secured data verification are also key differentiators.

The Squid SDK is a developer toolkit for building custom blockchain indexers and APIs on top of Subsquid's decentralized data layer. It supports multiple blockchain ecosystems and allows developers to tailor data pipelines to their specific needs.

Subsquid Cloud is a Platform-as-a-Service offering that lets developers deploy blockchain indexers without managing their own infrastructure. It is designed to simplify the process of building APIs and analytics dashboards that rely on on-chain data.

Subsquid was founded in 2021 by Dmitry Zhelezov and Marcel Fohrmann. The SQD token officially launched in 2024 following a public token sale on CoinList.

The SQD token is primarily deployed on Arbitrum, with additional deployments on BNB Smart Chain and Base. Arbitrum is the main chain for the token's network activity.
