Sei on SQD

Validated at ingestion

Sei 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

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

Full historical archive

SQD's Sei 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 Sei indexer on your own infrastructure or on SQD Cloud.

Frequently asked questions

How does SQD compare to running a Sei RPC node?

A Sei RPC node serves raw bytes for recent state and rate-limits per request. SQD's Portal pre-indexes the full Sei 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 Sei data?

Sei is available to Enterprise customers via SQD Private Portal. Contact us for pricing.

How is SQD's Sei data different from a block explorer like Etherscan?

Block explorers are read-optimized for human browsing of single blocks or addresses. SQD is built for programmatic indexing: stream millions of Sei 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 Sei explorer, the SQD Portal is what you would back it with.

Can I self-host SQD's Sei indexer?

Yes. Both the Squid SDK and the Pipes SDK are open-source. You can run a Sei 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 Sei data to a data warehouse or pipeline?

Yes. The Pipes SDK streams Sei 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 Sei data?

Every Sei 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 Sei data?

Sei historical data is available through the Portal archive. Real-time streaming for Sei is on the roadmap, contact us to flag your use case for prioritization.
