Bulk Evm Wallet Address Generator

EVM Address Generator is a Node.js library that generates Ethereum-compatible (EVM) addresses in bulk, with each address associated with a random value between 0.001 and 0.1. This tool is perfect for developers who need to create large sets of addresses for testing or other purposes.

Features

• Bulk Address Generation: Generate up to 100,000 Ethereum-compatible addresses.
• Random Value Assignment: Each address is paired with a random value between 0.001 and 0.1.
• CSV & Text File Output: Easily export addresses and values to a CSV or text file.
• Efficient and Fast: Optimized for performance to handle large-scale generation.

Installation

Before using the EVM Address Generator, ensure you have Node.js installed. Then, you can install the required dependencies:

npm install ethereumjs-wallet csv-writer

Usage

Basic Example

Here's a simple example to generate 100,000 addresses with random values and save them to a text file:

 const Wallet = require('ethereumjs-wallet').default;
const fs = require('fs');

const numAddresses = 100000;
let data = '';

// Generate addresses and random values
for (let i = 0; i < numAddresses; i++) {
    const wallet = Wallet.generate();
    const address = wallet.getAddressString();
    const randomValue = (Math.random() * (0.1 - 0.001) + 0.001).toFixed(4);

    data += `${address} ${randomValue}\n`;
}

// Write the data to a text file
fs.writeFile('evm_addresses_with_values.txt', data, 'utf8', (err) => {
    if (err) {
        console.error('Error writing to text file', err);
    } else {
        console.log('Text file was written successfully');
    }
});

CSV Output Example

If you prefer to export the generated addresses and values to a CSV file, you can use the following script:

const Wallet = require('ethereumjs-wallet').default;
const createCsvWriter = require('csv-writer').createObjectCsvWriter;

const numAddresses = 100000;
const csvWriter = createCsvWriter({
    path: 'evm_addresses_and_private_keys.csv',
    header: [
        { id: 'address', title: 'EVM Address' },
        { id: 'randomValue', title: 'Random Value' }
    ]
});

const records = [];

// Generate addresses and random values
for (let i = 0; i < numAddresses; i++) {
    const wallet = Wallet.generate();
    const address = wallet.getAddressString();
    const randomValue = (Math.random() * (0.1 - 0.001) + 0.001).toFixed(4);

    records.push({ address, randomValue });
}

// Write records to a CSV file
csvWriter.writeRecords(records)
    .then(() => console.log('CSV file written successfully'))
    .catch(err => console.error('Error writing CSV file', err));

Customization

Number of Addresses: You can adjust the number of addresses by modifying the numAddresses variable.
Random Value Range: The range of random values (0.001 to 0.1) can be customized by changing the parameters in the Math.random() function.

Security Considerations

Private Key Handling: This tool does not expose or save private keys when exporting data, ensuring the privacy and security of your generated addresses.
Performance: The script is optimized for generating large datasets quickly, but depending on your system's resources, generating 100,000 addresses may take some time.

Known Issues

Vulnerabilities: If you encounter vulnerabilities in the packages used, consider running npm audit fix or npm audit fix --force. See the npm documentation for more details.
