About Subsquid
Subsquid operates SQD, a data infrastructure stack for blockchain data comprising four integrated products: Portal (an HTTP API for raw blockchain data with streaming and finality handling), Network (a decentralized data lake with 2,000+ worker nodes and 225+ supported networks), SDK (TypeScript libraries — Squid SDK and Pipes SDK — for data transformation and persistence), and Cloud (a managed deployment platform). Every block is validated with six cryptographic checks at ingestion, replicated across the network, and delivered via a single streaming API to destinations like Snowflake, BigQuery, PostgreSQL, Kafka, and S3/GCS. The company serves institutional and enterprise clients in DeFi, compliance, trading, security, analytics, and prediction markets, with over $20B in TVL served by SQD-powered protocols, and is repositioning toward institutional clients under new CEO Wanja S. Oberhof. The stack is open-source (Portal software is AGPL-3.0 licensed Rust) and self-hostable, with an SQD token used for network staking and delegation.
