Unlimited Node for Web3 wallets: Scale with confidence and ease

Web3 wallets live and die by infrastructure performance. Whether it’s real-time balance updates, fast transaction broadcasting, or seamless multi-chain support—the backend must be fast, reliable, and scalable.

But performance isn’t the only challenge.

The real blocker is the pricing model.

Most RPC providers still tie billing to per-request charges, method-based multipliers, and usage-based pricing that penalizes growth.

The result?

For Web3 wallets, infrastructure costs are always too complex to predict.

The problem: RPC billing that punishes growth

As your wallet scales, infrastructure usage grows fast. Every user interaction—account lookup, eth_call, gas estimate—turns into multiple RPC calls.

Here’s what you’re actually paying for:

• Method-based multipliers (e.g., 10x–120x for eth_call, trace_*, or debug_*)
• API credits or compute units instead of real request counts
• PAYG pricing that fluctuates based on usage spikes
• Lack of visibility into what’s driving costs

Every real-time token update. Every gas estimate. Every nonce check.

It all adds up fast—especially during peak usage.

Under traditional billing models, scaling a wallet backend introduces friction at every stage:

• Unpredictable infrastructure costs that derail planning
• Usage caps that slow down feature rollouts
• Time lost tracking billing anomalies or debugging cost spikes
• Added complexity in monitoring and forecasting infrastructure spend

These challenges stem from opaque billing structures, including:

• Per-request charges that escalate with traffic
• Method-based multipliers that inflate usage costs
• Usage spikes that generate billing surprises
• Complex unit pricing models that are hard to track

Instead of focusing on product velocity, wallet teams end up firefighting infrastructure billing.

The solution: Unlimited Node

Unlimited Node is a new, transparent RPC billing model that replaces complexity with predictability.

You get unlimited RPC usage within a selected requests-per-second (RPS) tier, for a flat monthly fee.

Key benefits for Web3 wallet builders:

• Flat-rate pricing across clear RPS tiers (25 to 1,000 RPS)
• Unlimited usage within your tier—no per-call pricing
• No method multipliers or hidden costs
• Supports all Chainstack-supported protocols
• Built for high-throughput, production-grade workloads
