📱 Usage Guide

🔐 Generating a Wallet

Access the Application: Open the Web3-Wallet in your browser
Create Seed Phrase: Click the "Create Seed Phrase" button
Secure Your Mnemonic: Copy and securely store your 12-word mnemonic
Generate Addresses: Use "Add Ethereum Wallet" or "Add Solana Wallet" buttons

💳 Managing Multiple Wallets

// Each wallet follows BIP44 derivation paths:
// Ethereum: m/44'/60'/account'/0/address_index
// Solana: m/44'/501'/account'/0'

🌐 Using the DApp Browser

Navigate to DApp Browser: Click "DAppBrowser" in the navigation
Enter DApp URL: Input the URL of your desired DApp
Load DApp: Click "Load DApp" to interact with the application

📋 Copying Addresses

Click the copy button next to any generated address
The address will be copied to your clipboard
Visual feedback confirms successful copying

🔒 Security Features

🛡️ Security Best Practices

Client-Side Generation: All keys generated locally in your browser
No Server Storage: Mnemonics and private keys never leave your device
BIP39 Standard: Industry-standard mnemonic generation
Secure Randomness: Cryptographically secure random number generation

⚠️ Security Warnings

⚠️ IMPORTANT SECURITY NOTICE

Never share your mnemonic phrase with anyone

Store your mnemonic offline in a secure location

This is a demo application - do not use for storing significant funds

Always verify addresses before sending transactions

🔐 Recommended Security Practices

Backup Strategy: Write down your mnemonic on paper and store in multiple secure locations
Verification: Always verify generated addresses on multiple devices
Network Security: Use HTTPS and avoid public WiFi for wallet operations
Regular Updates: Keep the application and dependencies updated
