Hydration on SQD

Validated at ingestion

Hydration data is validated by SQD Network workers before it reaches the Portal. Validation is performed across the network rather than by a single ingestion node, so a faulty upstream source can't poison the dataset.

Decoded, schema-typed

Hydration data served as decoded, schema-typed tables, ready to query. Your indexer queries the data directly without writing SCALE parsers.

Full historical archive

SQD's Hydration archive covers historical state in one endpoint. Real-time on the roadmap.

Open-source SDK

Both the Squid SDK and the Pipes SDK are open-source. Connectors for Postgres, ClickHouse, MongoDB, SQLite and Parquet, plus a custom-target hook. Run your Hydration indexer on your own infrastructure or on SQD Cloud.

Frequently asked questions

How does SQD compare to running a Hydration RPC node?
A Hydration RPC node serves raw bytes for recent state and rate-limits per request. SQD's Portal pre-indexes the full Hydration archive into decoded, schema-typed tables (blocks, transactions, logs) and serves them as a single streaming endpoint. You skip the multi-day node sync, archive storage, monitoring, and scale-out work, and pay only for the data you stream.
What does SQD cost for Hydration data?
The public Portal endpoint at portal.sqd.dev/datasets/hydradx is free for development with no API key. Production workloads run on the SQD Portal with tiered pricing based on the network and request volume. See the pricing page for current tiers, or contact us for an enterprise quote.
How is SQD's Hydration data different from Subscan?
Block explorers are read-optimized for human browsing of single blocks or addresses. SQD is built for programmatic indexing: stream millions of Hydration blocks into your own database, run analytical queries across the full history, and back production applications with decoded data. Output is structured tables, not HTML pages, and there are no per-call rate limits geared toward UI traffic. If you wanted to build your own Hydration explorer, the SQD Portal is what you would back it with.
Can I self-host SQD's Hydration indexer?
Yes. Both the Squid SDK and the Pipes SDK are open-source. You can run a Hydration indexer on your own infrastructure pointing at the SQD Network or the Portal. SQD Cloud also offers managed hosting if you'd rather not operate it yourself.
Can I export Hydration data to a data warehouse or pipeline?
Yes. The Pipes SDK streams Hydration data from the Portal into Postgres, ClickHouse, MongoDB, SQLite, Parquet, or a custom target you implement. See the SDK docs for the connector reference.
Does SQD validate Hydration data?
Every Hydration block ingested into SQD is validated by the SQD Network workers (hash chain, parent reference, and where applicable finality) before it reaches the Portal. Validation is performed across the network, not by a single ingestion process, so a faulty upstream node can't poison the dataset.
Does SQD support real-time Hydration data?
Hydration historical data is available through the Portal archive. Real-time streaming for Hydration is on the roadmap, contact us to flag your use case for prioritization.
