ETH Vanity Address Generator for ESP8266/ESP32

A microcontroller-based Ethereum vanity address generator running on ESP8266 or ESP32. This program searches for Ethereum addresses starting with a specific prefix and sends the results via email.

Key Features

• Support for ESP8266 and ESP32
• Custom prefix Ethereum address search
• Automatic email notifications upon address discovery
• System monitoring and memory usage tracking
• Keccak-256 algorithm implementation for address generation
• Integrated WiFi connectivity

Requirements

• Hardware
• ESP8266 or ESP32 board
• Stable internet connection
• Software & Libraries
• Arduino IDE
• ESP Mail Client library
• WiFi library
• micro-ecc library
• Keccak library (included)

Configuration

Configure these variables in the main file before use:

// WiFi Configuration
const char* ssid = "your_ssid";
const char* password = "your_password";

// Email Configuration
#define SMTP_HOST "smtp.gmail.com"
#define SMTP_PORT 465
#define AUTHOR_EMAIL "your_email_address@gmail.com"
#define AUTHOR_PASSWORD "your_google_app_password"
#define RECIPIENT_EMAIL "recipient_email_address@gmail.com"

// Desired address prefix
const String TARGET_PREFIX = "0x0";

How It Works

1. Program initializes WiFi connection
2. Starts address search with specified prefix
3. For each attempt:
   • Generates random private key
   • Derives public key using secp256k1 curve
   • Generates Ethereum address using Keccak-256 algorithm
   • Checks if address matches desired prefix
4. When matching address is found, sends details via email

System Monitoring

The program includes system monitoring features displaying:

• Memory usage
• CPU frequency
• Flash chip speed
• Available sketch space
• Chip ID
