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

state_diffs

State changes per transaction, storage slot modifications, balance changes, and nonce updates.

How to index Avalanche blockchain data

Stream Avalanche event logs, 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 Avalanche blockchain data?

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

Is the Avalanche API free?

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

What Avalanche data tables does SQD provide?

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

Does SQD support real-time Avalanche data?

Yes. SQD provides sub-second latency on Avalanche mainnet through the Portal's hot path. Both real-time streaming and full historical access are available from the same API.

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

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