ethereumCLI is a professional and secure command-line Ethereum wallet built for developers and enthusiasts. It allows users to interact with the Ethereum blockchain for sending ETH, checking balances, generating wallets, and exploring transactions – all with transparency and security in mind.

• Generate a Wallet: Create a new Ethereum wallet with a private key and wallet address.
• Send Ethereum: Transfer ETH securely to any address on the Ethereum blockchain.
• Check Balance: Instantly check the ETH balance of your wallet.
• Transaction History: View the latest transactions for your wallet.
• Retrieve Address: Extract your wallet address from a private key if needed.
• Developer-Friendly: Built for developers who want a transparent and auditable CLI Ethereum wallet.

The principle of cryptocurrency is "Don't trust, verify". With ethereumCLI, you get complete transparency:

• The code is open-source, allowing you to inspect every function.
• ethereumCLI does not store or share your private key – you are in complete control.

💡 Tip: Always verify the code and the tool you’re using. Never blindly trust anyone in the crypto space, including me.

• Rust (for building the CLI wallet)
• Cargo (Rust package manager)
• Ethereum private key
• Infura API Key (or equivalent provider API)

To run ethereumCLI, you need to configure some environment variables. A sample .env-example file is provided to help you get started.

1. Locate the .env-example file in the project directory.
2. Copy it to create a new .env file:

   cp .env-example .env

3. Open the .env file and replace the placeholder values with your actual credentials:
   • PRIVATE_KEY: Your Ethereum private key (keep this secret and secure).
   • INFURA_API_KEY: Your Infura project API key for interacting with the Ethereum blockchain.

# Your Ethereum private key (KEEP THIS SECRET AND NEVER SHARE IT)
PRIVATE_KEY=your_private_key_here

# Infura API key for accessing Ethereum blockchain data
INFURA_API_KEY=your_infura_api_key_here

⚠️ Note: Never share your .env file or its contents with anyone. Your private key is critical for accessing your Ethereum wallet and must remain secure.

To compile the ethereumCLI wallet:

cargo build --release

To start ethereumCLI:

cargo run
