DFK Chain

DFK Chain

EVM Layer 1 / Chain ID 53935

DFK Chain is a EVM-compatible blockchain network indexed by the SQD Network. Access real-time and historical data including blocks, transactions, and event logs through the SQD Portal API.

DFK Chain on SQD

Validated at ingestion

DFK Chain 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

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

Full historical archive

SQD's DFK Chain 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 DFK Chain indexer on your own infrastructure or on SQD Cloud.

Build with DFK Chain data

Common production patterns teams build with SQD on DFK Chain.

DeFi & Trading

Index swaps, liquidations, and positions on DFK Chain in real time.

Analytics

Build dashboards and metrics from full DFK Chain historical state.

AI Agents

Give agents structured, decoded DFK Chain data with the MCP server.

Wallets & Payments

Power balance, transfer, and history views for DFK Chain wallets.

Compliance & KYT

Validated DFK Chain data for transaction monitoring and audits.

Stablecoins

Track every mint, burn, and transfer of DFK Chain stablecoins.

Real-World Assets

Auditable DFK Chain 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.

Frequently asked questions

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