Hemi

EVM Layer 2 / Chain ID 43111

Hemi is a modular Layer 2 that treats Bitcoin and Ethereum as one supernetwork. Its hVM embeds a full Bitcoin node inside an EVM, so contracts can read Bitcoin state directly.

Hemi on SQD

Validated at ingestion

Hemi 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

3 Hemi tables (blocks, transactions & logs), decoded and schema-typed, ready to query. Your indexer queries the data directly without writing RLP parsers.

Full historical archive

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

Build with Hemi data

Common production patterns teams build with SQD on Hemi.

Available Data

blocks

Block headers with timestamps, gas usage, miner info, and consensus data.

transactions

All onchain transactions with sender, receiver, value, gas, and input data.

logs

Event logs emitted by smart contracts, the primary source for tracking DeFi, NFT, and token activity.

Frequently asked questions

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