SQD

What is SQD?

SQD (formerly Subsquid) is a decentralized data lake and indexing framework that gives developers permissionless access to petabytes of onchain data. Its modular architecture separates data extraction from transformation, enabling indexers that are dramatically faster and cheaper than RPC-based alternatives.

Key Features

• SQD Network
  A decentralized data lake serving historical blockchain data for 100+ EVM and Substrate networks plus Solana.

• Squid SDK
  A TypeScript framework for building custom indexers (squids) with GraphQL or database outputs.

• High Throughput
  Batch-based extraction delivers indexing speeds far beyond traditional subgraph approaches.

• Flexible Deployment
  Run squids self-hosted or on SQD Cloud, with support for real-time and historical data.
