SQD Network provides superior data access compared to conventional chain node
RPCs through its rich streaming and filtering capabilities, allowing you to
query multiple blocks simultaneously.
How SQD Network Works
SQD Network stores blockchain data in a distributed data lake, making it available through SQD Portal—a high-performance data access interface that fetches data chunks from multiple worker nodes in parallel. Portal exposes a streaming HTTP API optimized for data extraction at scale. It handles pagination, finality tracking, and reorg compensation automatically, so you can focus on building your application rather than managing infrastructure complexity. You can access the network in three ways:- Use managed Portal endpoints - SQD-hosted endpoints provide instant access to 200+ networks with zero setup
- Self-host Portal - Run your own Portal instance alongside your nodes for complete data sovereignty
- Use the SDK - Build production indexers with TypeScript SDKs that abstract Portal’s API into a developer-friendly interface
Network Options
SQD Network operates in two configurations, both freely accessible and using the same Portal API:| Feature | Permissionless Network | Private Network |
|---|---|---|
| Status | Mainnet (Portal in public beta) | Production-ready |
| Infrastructure | Fully decentralized | Operated by Subsquid Labs GmbH |
| Participation | Anyone can run workers or delegate | Permissioned |
| Networks supported | Almost all | 200+ networks |
Both networks are free to query. See the complete list of supported
networks for gateway URLs and network details.
Participate in the Permissionless Network
The decentralized network is now in mainnet, and you can participate in two ways:Run a Worker Node
Contribute storage and compute resources to the network and earn SQD tokens
Delegate SQD Tokens
Reward high-performing workers and share in their profits
