How to index zkVerify blockchain data

Stream zkVerify transactions and blocks from the SQD Portal in two lines of code. The example below uses the public endpoint, no API key required for development.

Frequently asked questions

How do I index zkVerify blockchain data?

Use the SQD Portal API at portal.sqd.dev/datasets/zkverify-mainnet or the open-source Squid SDK. Both stream zkVerify blocks, transactions, and onchain events from historical archives. The free tier supports development; paid Portal deployments cover production workloads with SLA-backed latency.

Is the zkVerify API free?

Yes. SQD provides a free public Portal endpoint for zkVerify with no API key required. For higher rate limits, dedicated infrastructure, and SLA-backed uptime, see the SQD Pricing page.

What zkVerify data tables does SQD provide?

SQD indexes the standard set of zkVerify data including blocks, transactions, and onchain events. All data is decoded and validated at ingestion.

Does SQD support real-time zkVerify data?

zkVerify historical and recent data is available through SQD's archival layer. Real-time streaming for zkVerify is on the roadmap, request priority via the SQD contact form.

What's the difference between SQD and an RPC node for zkVerify?

An RPC node serves raw, unvalidated zkVerify data limited to recent state. SQD's Portal indexes the full zkVerify history, decodes it into queryable tables, validates every block at ingestion, and serves it through a typed SDK, no node operations required.

Can I self-host zkVerify indexing with SQD?

Yes, the Squid SDK is open-source under the GPLv3 license. You can run your own indexer against the SQD Network or the Portal, or deploy on SQD Cloud for fully managed hosting.
