Frequently asked questions

How do I index Katana blockchain data?

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

Is the Katana API free?

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

What Katana data tables does SQD provide?

SQD indexes 5 data tables for Katana: blocks, transactions, logs, traces, state_diffs. Each table is decoded, validated at ingestion, and queryable through the Portal API.

Does SQD support real-time Katana data?

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

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

An RPC node serves raw, unvalidated Katana data limited to recent state. SQD's Portal indexes the full Katana 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 Katana 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.
