BOB on SQD

Validated at ingestion

BOB 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

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

Full historical archive

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

Build with BOB data

Common production patterns teams build with SQD on BOB.

DeFi & Trading

Index swaps, liquidations, and positions on BOB in real time.

Analytics

Build dashboards and metrics from full BOB historical state.

AI Agents

Give agents structured, decoded BOB data with the MCP server.

Wallets & Payments

Power balance, transfer, and history views for BOB wallets.

Compliance & KYT

Validated BOB data for transaction monitoring and audits.

Stablecoins

Track every mint, burn, and transfer of BOB stablecoins.

Real-World Assets

Auditable BOB data for tokenized RWA issuance and transfers.

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.

state_diffs

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

Frequently asked questions

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