Frequency on SQD

Validated at ingestion

Frequency 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

Frequency 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 Frequency 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 Frequency indexer on your own infrastructure or on SQD Cloud.

Build with Frequency data

Common production patterns teams build with SQD on Frequency.

DeFi & Trading

Index swaps, liquidations, and positions on Frequency in real time.

Analytics

Build dashboards and metrics from full Frequency historical state.

AI Agents

Give agents structured, decoded Frequency data with the MCP server.

Wallets & Payments

Power balance, transfer, and history views for Frequency wallets.

Compliance & KYT

Validated Frequency data for transaction monitoring and audits.

Stablecoins

Track every mint, burn, and transfer of Frequency stablecoins.

Real-World Assets

Auditable Frequency data for tokenized RWA issuance and transfers.

Frequently asked questions

How does SQD compare to running a Frequency RPC node?
A Frequency RPC node serves raw bytes for recent state and rate-limits per request. SQD's Portal pre-indexes the full Frequency 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 Frequency data?
The public Portal endpoint at portal.sqd.dev/datasets/frequency 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 Frequency 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 Frequency 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 Frequency explorer, the SQD Portal is what you would back it with.
Can I self-host SQD's Frequency indexer?
Yes. Both the Squid SDK and the Pipes SDK are open-source. You can run a Frequency 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 Frequency data to a data warehouse or pipeline?
Yes. The Pipes SDK streams Frequency 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 Frequency data?
Every Frequency 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 Frequency data?
Frequency historical data is available through the Portal archive. Real-time streaming for Frequency is on the roadmap, contact us to flag your use case for prioritization.
