# SQD

> The onchain data layer — validated, real-time blockchain data from 225+ networks through a single streaming API.

SQD (formerly Subsquid) provides blockchain data infrastructure. The stack includes a decentralized data lake (SQD Network), a streaming HTTP API (Portal), two TypeScript SDKs (Squid SDK for indexers, Pipes SDK for composable streaming pipelines), and a managed deployment platform (SQD Cloud).

## Products

- [Portal API](https://sqd.dev/portal): Streaming HTTP API for raw blockchain data — blocks, transactions, logs, traces, state diffs across 225+ EVM, Solana, Bitcoin, and Hyperliquid networks
- [Squid SDK](https://sqd.dev/sdk): TypeScript ETL framework for batch-processing and indexing onchain data into custom databases
- [Pipes SDK](https://sqd.dev/sdk#pipes-sdk): Composable TypeScript streaming library for data pipelines — outputs to ClickHouse, BigQuery, Snowflake, Parquet/S3
- [SQD Cloud](https://sqd.dev/cloud): Managed deployment platform for Squid indexers with monitoring and auto-scaling
- [SQD Network](https://sqd.dev/network): Decentralized data lake with 2,000+ worker nodes storing blockchain data in Parquet format
