RPC Request Batching Optimizer

WHAT IT DOES

RPC Request Batching Optimizer helps you reduce RPC call overhead and improve performance by generating optimized batching configurations. You provide your RPC endpoint, default batch size, concurrency level, and method-specific batching rules. The tool generates a configuration file with optimized batch sizes for each method, priority settings, and concurrency parameters. It also provides performance estimates showing how batching reduces total RPC calls. This is essential for developers running indexers, frontends, or any application that makes frequent RPC calls where reducing the number of requests can dramatically improve performance, reduce latency, and lower RPC provider costs.

HOW TO USE

Enter your RPC endpoint URL. Set a default batch size (the number of requests to group per batch) and concurrency level (how many batches to run in parallel). Define method-specific rules—one per line—in the format "method | batch_size | priority". For example: "eth_getBalance | 20 | high", "eth_call | 15 | high", or "eth_getLogs | 5 | medium". Priority can be high, medium, or low. Click "Generate Batch Optimization." The tool builds a complete optimization configuration, displays a summary of your settings and rules, and shows performance estimates including estimated request reduction and savings percentage. Use the copy button to export the configuration for use with your RPC client or batching middleware.

THE REAL MECHANISM

The tool uses a pure JavaScript template engine that operates entirely client-side. It takes the user-provided default batch size, concurrency, and method rules, and generates a structured configuration file. The configuration includes the RPC URL, default batch size, concurrency level, timeout in milliseconds, and method-specific rules with batch sizes and priorities. The tool also calculates performance estimates: it multiplies each method's batch size by the number of methods to estimate total unbatched requests, then calculates the optimized request count by reducing the batch size per method. The savings percentage is computed as the reduction in total requests. All processing is done in the browser—no data is sent to external servers, and no actual RPC calls are made.

WHAT IT CANNOT SEE

This tool cannot automatically determine the optimal batch size for all RPC endpoints—you must choose appropriate values based on your RPC provider's limits and your application's needs. It cannot detect if the generated batching strategy will work with the user's specific environment or RPC client. It cannot generate configurations for non-EVM RPCs. It cannot test batch performance or success rates—it only provides estimates. It cannot monitor RPC rate limits automatically. The tool does not execute any RPC calls or validate that the RPC endpoint is reachable.

PLEASE NOTE

RPC Request Batching Optimizer works for any EVM-compatible RPC endpoint and does not require a blockchain connection to function, though the network selector is provided for context. It is a configuration tool for developers, not an execution tool. It reads data only and does not send any information to external servers. The tool is free to use and does not require authentication. For best results, test your batch sizes with your specific RPC provider to find the optimal balance between request reduction and latency.
