zkSync Era on SQD

Validated at ingestion

zkSync Era 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

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

Archive plus real-time

Single Portal endpoint serves zkSync Era from genesis through the current head, with sub-second hot-path latency. No separate streaming pipeline to wire up.

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 zkSync Era indexer on your own infrastructure or on SQD Cloud.

Build with zkSync Era data

Common production patterns teams build with SQD on zkSync Era.

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.

traces

Internal transactions and call traces showing the full execution path of each transaction.

Frequently asked questions

How does SQD compare to running a zkSync Era RPC node?
A zkSync Era RPC node serves raw bytes for recent state and rate-limits per request. SQD's Portal pre-indexes the full zkSync Era archive into decoded, schema-typed tables (blocks, transactions, logs & traces) 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 zkSync Era data?
The public Portal endpoint at portal.sqd.dev/datasets/zksync-mainnet 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 zkSync Era 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 zkSync Era 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 zkSync Era explorer, the SQD Portal is what you would back it with.
Can I self-host SQD's zkSync Era indexer?
Yes. Both the Squid SDK and the Pipes SDK are open-source. You can run a zkSync Era 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 zkSync Era data to a data warehouse or pipeline?
Yes. The Pipes SDK streams zkSync Era 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 zkSync Era data?
Every zkSync Era 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 zkSync Era data?
Yes. zkSync Era is served with both real-time and historical data from the same Portal endpoint, with sub-second latency on the hot path. No separate streaming pipeline to wire up.
