Solana Transaction Spammer

This Rust application is designed to generate a high volume of Solana transactions, primarily for stress testing and performance analysis of Solana clusters. It leverages the Solana SDK and asynchronous operations via tokio to achieve efficient transaction submission.

Features

• High-Throughput Transaction Generation: Sends numerous concurrent transactions to a specified Solana address.
• Configurable Parameters: Allows customization of the RPC URL, recipient address, private key, and number of concurrent tasks through environment variables.
• .env Configuration: Utilizes a .env file for easy and secure management of sensitive configuration details.
• Asynchronous Operations: Employs tokio for efficient concurrent transaction submission.
• Real-time Statistics: Provides feedback on transaction submission rate and elapsed time.
• Pre-Spam Test Transaction: Executes a single test transaction to verify connectivity and configuration before initiating the main spamming loop.

Getting Started

Prerequisites

• Rust and Cargo: Ensure you have Rust and Cargo installed on your system. You can download them from rustup.rs.
• Solana CLI (Optional): While not strictly necessary for running the application, having the Solana CLI installed can be useful for interacting with the Solana network.

Installation

1. Clone the Repository:

   git clone <repository_url>
   cd solana-spammer

2. Configure Environment Variables:

   • Create a .env file in the root directory of the project.

   • Add the following environment variables to the .env file, replacing the placeholder values with your actual data:

     RPC_URL="<your_solana_rpc_url>"
     RECIPIENT_ADDRESS="<recipient_solana_address>"
     PRIVATE_KEY_BYTES="<comma_separated_private_key_bytes>"
     NUM_TASKS="128" # Optional: Adjust the number of concurrent tasks
     

     Important: Handle your private key with extreme caution. Avoid committing it to version control.

3. Build the Project:

   cargo build --release # use release for better performance

4. Run the Application:

   cargo run --release

   The application will prompt you to confirm if you want to start spamming. Type y and press Enter to begin.

Usage Notes

• Security: Exercise extreme caution when handling your private key. Never commit it to version control or share it.
• Network Responsibility: Use this tool responsibly and ethically. Only use it on networks where you have explicit permission.
• Sufficient SOL: Ensure that the sender account has sufficient SOL to cover transaction fees.
• Performance Tuning: The NUM_TASKS parameter significantly impacts performance. Adjust it based on your system's capabilities and the network's capacity.
