SQD Network by Subsquid Labs GmbH is a decentralized blockchain data indexing and query platform designed to provide fast, scalable, and cost-efficient access to on-chain data across more than 150 networks. It supports a wide range of blockchain ecosystems including Ethereum Virtual Machine (EVM) compatible chains, Substrate-based chains, Solana (beta), Tron, Starknet, and Fuel. The platform enables developers to extract, transform, and query historical and real-time blockchain data with high throughput and reliability, addressing the challenges of traditional indexing solutions that rely on centralized RPC nodes.

The core of the platform is the SQD Network, a decentralized data lake and query engine that powers various complementary products such as the Squid SDK, SQD Cloud, and SQD Portal. The Squid SDK is an open-source TypeScript toolkit that allows developers to build high-performance batch indexers without the need to manage archival RPC infrastructure. SQD Cloud offers a managed hosting service for deploying and scaling custom indexers with zero downtime, while SQD Portal provides a new blockchain data standard for real-time data access.

What sets SQD apart is its decentralized architecture, which ensures data consistency and reliability even for smaller or less popular networks. It offers up to 100x faster indexing compared to alternatives like The Graph, while reducing data extraction costs by up to 90%. The platform also supports advanced features such as indexing of internal contract calls, transaction traces, state diffs, and WASM smart contracts developed with ink!. SQD’s tokenomics include a deflationary model and a revenue capture mechanism that aligns incentives for node operators, delegators, and token holders.

Developers can get started quickly using the comprehensive documentation and example indexers provided in the Squid SDK. The platform supports integration with popular developer tools like ApeWorx and offers GraphQL subscriptions for live query updates. SQD Network is actively maintained and supported by a growing community, with a public Discord server and regular updates. Its decentralized approach and broad network support make it suitable for DeFi analytics, gaming data indexing, DAO tooling, and AI-driven Web3 applications.
