Unlimited Node for blockchain data: Scale your analytics without scaling your costs

Data engineers know the pain of working with blockchain data:

You’re not just pulling a few wallet balances—you’re scanning millions of records, querying deeply nested contracts, and backfilling months (or years) of history across multiple chains.

And what’s standing in the way isn’t the tech.

It’s the cost of access.

The hidden cost of blockchain data retrieval

When you’re indexing blockchain data for dashboards, APIs, or internal models, the workload isn’t light:

• High-frequency polling
• Large batch archive lookups
• Deep debug_trace and eth_getLogs operations
• Cross-chain event tracking

And with most RPC providers, the more valuable the method, the more you’re charged.

Method, weight	Chainstack	Provider 1	Provider 2
eth_call	1	20	26
eth_getLogs	1	20	60
eth_blockNumber	1	20	10
eth_getFilterChanges	1	20	20

This pricing model creates constant friction:

• Incomplete datasets due to API caps
• Long ingestion cycles to avoid cost overruns
• Delayed delivery of insights and reports
• Time spent optimizing infra instead of pipelines

Unlimited Node: The end of per-request pricing

Unlimited Node is a new billing model designed to support large-scale, method-heavy workloads—exactly like blockchain analytics.

It’s simple:

You pick a requests-per-second (RPS) tier. You pay a flat monthly fee.

Then you get unlimited usage within that tier across all methods and networks.

1. No per-method multipliers.
2. No credits.
3. No cost spikes.

Whether you’re running 1M+ archive queries per day, polling 20 chains in parallel, or live-tracing forensics across EVM, your bill remains flat.

What makes Chainstack different for analytics

Unlimited Node is part of a broader platform built for high-throughput data infrastructure:

• Flat, transparent pricing with no usage-based surprises
• High-performance archive access optimized for bulk methods
• Low-latency RPC endpoints across regions
• 99.99% uptime and monitoring
• Unified multi-chain access from a single console

Use case: High-volume, cross-chain analytics

Let’s say you’re building a product that:

• Monitors smart contract security threats
• Indexes token transfer data across chains
• Feeds real-time DeFi metrics into dashboards

With traditional infrastructure, every deep trace, every call to debug methods adds hidden costs that compound with growth.

With Unlimited Node, your costs stay flat:

• Pick your RPS tier (from 25 to 1,000 RPS)
• Query real-time and historical data freely
• Build long-running pipelines with no throttling
• Plan spend and scale predictably

How to get started

1. Log in to the Chainstack console
2. Deploy your node(s) for the chain(s) you support
3. Apply the Unlimited Node add-on
4. Choose the RPS tier that fits your data load
5. Start building without counting requests

Unlimited Node is available from the Growth plan. You can mix Unlimited and quota-based nodes for complete control.
