Unlimited Node for traders: Execute faster, scale smarter

In trading, milliseconds matter.

Every failed transaction. Every delayed confirmation. Every missed on-chain signal—it’s money left on the table.

Trading infrastructure must be fast, accurate, and battle-tested. But more often than not, the biggest tradeoff isn’t latency.

It’s the pricing model.

What’s slowing down your edge?

High-performance trading bots and strategy engines rely on a constant stream of on-chain data:

• Monitoring mempool events
• Watching liquidity pools
• Tracking token approvals
• Calculating slippage in real-time
• Executing transactions before price windows close

But most RPC providers charge you based on how much you use—or worse, how “heavy” your methods are.

For trading systems, this creates real-world problems:

• Unpredictable infrastructure costs
• Method multipliers that penalize performance-sensitive logic
• Usage spikes during volatile markets that lead to billing surprises
• Extra complexity in managing infrastructure budgets

This isn’t just inefficient—it’s risky.

Unlimited Node: Built for trading-grade infrastructure

Unlimited Node is Chainstack’s solution for trading systems that demand consistency, speed, and cost clarity.

You get unlimited RPC usage within a chosen RPS (requests-per-second) tier—for a flat monthly fee. No matter how many eth_call, eth_getTransactionByHash, or eth_getBlockByNumber requests you fire.

• No method multipliers
• No per-request pricing
• No surprise billing at peak hours

You select the throughput your strategy needs—starting at 25 RPS and up to 1,000 RPS—and your cost stays flat.
