# SQD Network > The Data Lake for AI Agents SQD provides developers with fast access to blockchain data through a decentralized data lake and query engine across multiple networks. SQD helps developers access blockchain data efficiently through a decentralized data lake and query engine supporting multiple networks. Users can extract, transform, and serve blockchain data at scale, build custom indexers and APIs, and integrate with multiple blockchain ecosystems. SQD was acquired by Rezolve AI in January 2025, officially rebranded from Subsquid in July 2024. - Type: Company - Sector: Data & Analytics - Status: Acquired - Profile: https://thegrid.id/profiles/sqd_network ## Products - [SQD Network](https://thegrid.id/profiles/sqd_network): SQD Network operates as a decentralized query engine optimized for batch extraction of large volumes of blockchain data from multiple networks. The system provides multiple access methods including Squid SDK for self-hosted development, SQD Cloud for hosted services, SQD Firehose for subgraph compatibility, and framework integrations. Users can extract, transform, and serve blockchain data at up to 100x faster speeds compared to traditional RPC methods. (OnChain Data API, Live, Main Product) - [Squid SDK](https://thegrid.id/profiles/sqd_network): A TypeScript toolkit for high-performance batch indexing of blockchain data sourced from SQD Network. The SDK provides modular architecture for data extraction, transformation, and persistence with processors for EVM and Substrate chains, typegen utilities for smart contract decoding, and support for multiple data stores including PostgreSQL, file systems, and BigQuery. (Developer Tooling, Live) - [SQD Cloud](https://thegrid.id/profiles/sqd_network): A platform-as-a-service for hosting custom blockchain indexers and GraphQL APIs. The service handles resource provisioning, database migrations, and infrastructure maintenance for production-ready indexing pipelines. Features include dedicated deployment profiles, PostgreSQL and Hasura addons, RPC proxy endpoints, API scaling with load balancing, and zero-downtime updates through deployment slots. (Developer Tooling, Live) - [SQD Firehose](https://thegrid.id/profiles/sqd_network): A lightweight adapter for running subgraphs against SQD Network without requiring archival RPC nodes. The adapter operates as a sidecar to graph indexer nodes, ingesting and filtering historical data from SQD Network while optionally fetching recent unfinalized blocks from RPC endpoints. Enables deployment of existing subgraphs without code modifications. (Developer Tooling, Live) - [ApeWorx SQD Plugin](https://thegrid.id/profiles/sqd_network): A plugin for ApeWorx Python framework enabling bulk blockchain data retrieval from SQD Network. The plugin provides orders of magnitude faster data access compared to RPC-based sources for queries spanning more than 1,000 blocks. Supports block queries, event log retrieval, and historical account data access through ApeWorx's query interface. (Developer Tooling, Open Beta) ## Assets - [Subsquid (SQD)](https://thegrid.id/profiles/sqd_network): SQD is the utility token of SQD Network, a decentralized data lake and query engine for blockchain data. It is used to reward node operators, stake and delegate to curate trusted workers, and adjust rate limits for data access. Holders lock SQD to influence bandwidth allocation, making the token central to how the network distributes and prioritizes data query capacity.
