account_balance_walletD-IBAN

Integrating D-IBAN into a Dogecoin wallet is straightforward. The D-IBAN library is lightweight (~10KB) and can be easily integrated into mobile apps, web wallets, or desktop applications.

Step 1: Include the Library

For Web Wallets:

<script src="js/diban.js"></script>

For Node.js/React Native:

const { encodeDIBAN, decodeDIBAN, verifyDIBAN } = require('./js/diban.js');

Step 2: Generate D-IBAN for User Addresses

When displaying a user's receive address, generate and show the D-IBAN format:

// User's Dogecoin address
const userAddress = "DTqAFgNNUgiPEfFmc4HZUkqJ4sz5vADd1n";

// Generate D-IBAN
const result = encodeDIBAN(userAddress);

// Display both formats
console.log("Dogecoin Address:", userAddress);
console.log("D-IBAN Code:", result.diban);
console.log("Address Type:", result.type.name);

Step 3: Accept D-IBAN for Payments

Allow users to paste D-IBAN codes when sending payments:

// User pastes D-IBAN
const userInput = "DO12 0000 1234 5678 9012 3456 7890 1234 5678 9012 3456 789";

// Verify first
if (verifyDIBAN(userInput)) {
    // Decode to Dogecoin address
    const decoded = decodeDIBAN(userInput);
    
    // Use the address for payment
    sendPayment(decoded.address, amount);
} else {
    showError("Invalid D-IBAN code");
}

Step 4: Display D-IBAN in QR Codes

Include D-IBAN in QR codes for easy sharing:

// Generate QR code with both formats
const qrData = {
    address: userAddress,
    diban: result.diban,
    type: result.type.name
};

generateQRCode(JSON.stringify(qrData));

Benefits for Wallet Users

• Banking Integration: Users can share D-IBAN codes with banks and payment processors
• Easy Sharing: D-IBAN format is familiar and easy to share
• Error Detection: Built-in checksum prevents typos
• Multiple Formats: Display both traditional address and D-IBAN
• Type Information: Automatically detects and displays address type

UI Integration Example

Add a toggle or button to show D-IBAN format:

// In your wallet UI
function showReceiveAddress(address) {
    const diban = encodeDIBAN(address);
    
    return `
        <div class="address-display">
            <button onclick="toggleFormat()">Show D-IBAN</button>
            <div class="address">${address}</div>
            <div class="diban" style="display: none;">${diban.diban}</div>
            <div class="type">Type: ${diban.type.name}</div>
        </div>
    `;
}

Note: The D-IBAN library is lightweight and works in both browser and Node.js environments. No external dependencies are required.

Banks can implement D-IBAN with minimal structural changes because it uses the same ISO 13616-1:2020 standard that banks already use for traditional IBAN processing.

Why Minimal Changes Are Needed

• Same ISO Standard: D-IBAN uses ISO 13616-1:2020 - the exact same standard banks use
• Same Validation: MOD-97-10 checksum algorithm (already implemented)
• Same Format: Standard IBAN structure banks already process
• Reuses Infrastructure: Existing IBAN validation, routing, and processing systems

Implementation Approach: Country Code Registration

The recommended approach is to register "DO" as an official IBAN country code for Dogecoin. Banks can then treat D-IBAN codes like any other international IBAN.

Step 1: Add Country Code Routing

Add one condition to your existing IBAN router:

function routeIBAN(iban) {
    const countryCode = iban.substring(0, 2);
    
    // Add this condition (new)
    if (countryCode === "DO") {
        return processDogecoinIBAN(iban);
    }
    
    // Existing routing (unchanged)
    return processTraditionalIBAN(iban);
}

Step 2: Reuse Existing Validation

Your existing IBAN validator already works for D-IBAN:

// Existing validation function (no changes needed)
function validateIBAN(iban) {
    const clean = iban.replace(/\s+/g, "");
    const rearr = clean.slice(4) + clean.slice(0, 4);
    return mod97Check(rearr) === 1;  // Works for D-IBAN too!
}

Step 3: Create Dogecoin Processing Module

Create an isolated module for Dogecoin processing:

// New module (isolated, ~260 lines of code)
function processDogecoinIBAN(diban) {
    // Decode D-IBAN to Dogecoin address
    const { address, type } = decodeDIBAN(diban);
    
    // Process using existing payment infrastructure
    return processPayment({
        address: address,
        type: type.name,
        blockchain: 'dogecoin'
    });
}

What Banks Need to Change

Existing Systems (No Changes):

• ✅ IBAN validation engine
• ✅ MOD-97-10 checksum algorithm
• ✅ Payment routing infrastructure
• ✅ Transaction processing systems
• ✅ Account management

New Components (Isolated):

• ⚪ D-IBAN decoder module (~200 lines)
• ⚪ Dogecoin address validator (~50 lines)

• ⚪ Optional: D-IBAN mapping table

Implementation Phases

1. Week 1: Validation Integration - Add D-IBAN validation (Low Risk)
2. Week 2: Routing Integration - Add "DO" country code routing (Low Risk)
3. Week 3-4: Processing Integration - Implement Dogecoin payment processing (Medium Risk)
4. Week 5-6: Testing & Deployment - End-to-end testing and gradual rollout

Benefits for Banks

• Leverage Existing Infrastructure: Reuse IBAN validation, payment processing, and compliance systems
• Minimal Development Cost: ~260 lines of isolated, testable code
• Standards Compliant: Uses existing ISO 13616-1:2020 standard
• Low Risk: Isolated module, easy to test and deploy
• Future-Proof: Easy to add other cryptocurrencies

Complete Integration Example

// Existing Payment Service (minimal modification)
class PaymentService {
    async process(iban, amount) {
        // Validate (works for D-IBAN)
        if (!this.ibanService.validate(iban)) {
            throw new Error("Invalid IBAN");
        }
        
        const countryCode = iban.substring(0, 2);
        
        // Add Dogecoin routing (new)
        if (countryCode === "DO") {
            return await this.processDogecoin(iban, amount);
        }
        
        // Existing processing (unchanged)
        return await this.processTraditional(iban, amount);
    }
    
    // New method (isolated)
    async processDogecoin(diban, amount) {
        const { address } = decodeDIBAN(diban);
        return await this.blockchainService.send(address, amount);
    }
}

Steganography allows you to hide a Dogecoin address or private key inside an image using LSB (Least Significant Bit) encoding. The encoded image looks identical to the original, making it perfect for sharing addresses or securely storing private keys in a hidden way.

Key Features:

• Invisible Encoding: The encoded image looks identical to the original - no visible changes
• LSB Technique: Uses Least Significant Bit encoding in RGB channels for maximum stealth
• Lossless: 100% reversible - can decode back to original address or private key
• Type Detection: Automatically detects and encodes address type (P2PKH, P2SH, P2WPKH) or private key (WIF format)
• Universal: Works with any Dogecoin address type and WIF private keys
• PNG Format: Encoded images are saved as PNG to preserve pixel data
• Private Key Support: Securely encode and decode WIF format private keys

How It Works:

• Encoding: Converts Dogecoin address or private key to bytes and embeds them in the LSB of image pixels
• Magic Marker: Uses "DOGE" marker to identify encoded images
• Type Byte: Stores data type (address or private key) for proper decoding
• Length Header: Stores data length for proper decoding
• Pixel Storage: Each pixel stores 3 bits (one in each RGB channel)
• Decoding: Extracts LSB from pixels and reconstructs the address or private key

Use Cases: Perfect for sharing addresses in images, hiding addresses in artwork, securely storing private keys in images, creating secret address/private key sharing methods, and making cryptocurrency data more shareable through images!

⚠️ Security Warning: Be extremely careful when encoding private keys. Never share images containing private keys publicly, as anyone who decodes the image will have access to your funds!

Note: The image must be large enough to store the address. Smaller images may not have enough pixels. PNG format is recommended for best results.
