Polymesh

Substrate Substrate

Polymesh is a Substrate-based blockchain network indexed by the SQD Network. Access real-time and historical data including blocks, transactions, and event logs through the SQD Portal API.

Polymesh on SQD

Validated at ingestion

Polymesh 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

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

Build with Polymesh data

Common production patterns teams build with SQD on Polymesh.

DeFi & Trading

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

Analytics

Build dashboards and metrics from full Polymesh historical state.

AI Agents

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

Wallets & Payments

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

Compliance & KYT

Validated Polymesh data for transaction monitoring and audits.

Stablecoins

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

Real-World Assets

Auditable Polymesh data for tokenized RWA issuance and transfers.

Frequently asked questions

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