Frequently asked questions

How do I index Hydration blockchain data?

Use the SQD Portal API at portal.sqd.dev/datasets/hydradx or the open-source Squid SDK. Both stream Hydration blocks, transactions, and onchain events from historical archives. The free tier supports development; paid Portal deployments cover production workloads with SLA-backed latency.

Is the Hydration API free?

Yes. SQD provides a free public Portal endpoint for Hydration with no API key required. For higher rate limits, dedicated infrastructure, and SLA-backed uptime, see the SQD Pricing page.

What Hydration data tables does SQD provide?

SQD indexes the standard set of Hydration data including blocks, transactions, and onchain events. All data is decoded and validated at ingestion.

Does SQD support real-time Hydration data?

Hydration historical and recent data is available through SQD's archival layer. Real-time streaming for Hydration is on the roadmap, request priority via the SQD contact form.

What's the difference between SQD and an RPC node for Hydration?

An RPC node serves raw, unvalidated Hydration data limited to recent state. SQD's Portal indexes the full Hydration history, decodes it into queryable tables, validates every block at ingestion, and serves it through a typed SDK, no node operations required.

Can I self-host Hydration indexing with SQD?

Yes, the Squid SDK is open-source under the GPLv3 license. You can run your own indexer against the SQD Network or the Portal, or deploy on SQD Cloud for fully managed hosting.
