### Utility Functions

All utility functions and constants can also be imported from the library:

```typescript
import { 
  initProvider, 
  initProviderNoSigner, 
  loadKeypairFromBase58, 
  loadKeypairFromFile,
  validateImageFile,
  CONFIGS,
  NetworkType 
} from '@flipflop-sdk/node';
```

## Configuration

### Network Types
- `mainnet`: Production network
- `devnet`: Development network  
- `local`: Local validator

### Token Types
- `meme`: Aggressive parameters for community tokens
- `standard`: Conservative parameters for utility tokens

### RPC Endpoints
- **Mainnet**: `https://api.mainnet-beta.solana.com`
- **Devnet**: `https://api.devnet.solana.com`
- **Local**: `http://127.0.0.1:8899`

### Irys Network Integration
- **Devnet**: `https://api-dev.flipflop.plus/api/irys/upload`
- **Mainnet**: `https://api.flipflop.plus/api/irys/upload`
- **Gateway**: `https://gateway.irys.xyz/`

## Authentication

The SDK supports two methods for providing keypairs:

### 1. Base58 Encoded Private Key
```javascript
const result = await launchToken({
  // ... other options
  keypairBs58: 'your-base58-encoded-private-key'
});
```

### 2. Keypair File Path
```javascript
const result = await launchToken({
  // ... other options
  keypairFile: './path/to/keypair.json'
});
```

## Error Handling

All functions throw descriptive errors for validation and runtime issues:

```javascript
try {
  // Validate image first
  const validation = validateImageFile('./logo.png');
  if (!validation.valid) {
    throw new Error(`Image validation failed: ${validation.error}`);
  }

  // Generate metadata
  const metadataResult = await generateMetadataUri({
    rpc: 'https://api.devnet.solana.com',
    name: 'My Token',
    symbol: 'MTK',
    description: 'My awesome token',
    imagePath: './logo.png'
  });

  if (!metadataResult.success) {
    throw new Error(`Metadata upload failed: ${metadataResult.error}`);
  }

  // Launch token
  const result = await launchToken({
    rpc: 'https://api.devnet.solana.com',
    name: 'My Token',
    symbol: 'MTK',
    tokenType: 'meme',
    uri: metadataResult.metadataUrl,
    keypairBs58: 'invalid-key'
  });
} catch (error) {
  console.error('Operation failed:', error.message);
}
```

- `@solana/web3.js` (^1.98.0) - Solana Web3 JavaScript API
- `@solana/spl-token` (^0.4.9) - SPL Token library
- `@solana/spl-token-metadata` (^0.1.6) - Token metadata standard

**Utility Libraries:**
- `axios` (^1.11.0) - HTTP client for API requests
- `form-data` (^4.0.4) - Multipart form data for file uploads
- `bn.js` (5.2.1) - Big number arithmetic
- `bs58` (^6.0.0) - Base58 encoding/decoding

- `sleep-promise` (^9.1.0) - Promise-based sleep utility

### Building

```bash
# Install dependencies
npm install

# Build the library
npm run build

# Run tests
npm test

# Watch mode for development
npm run dev
```

### Testing

```bash
# Run all tests
npm test

# Run specific test file
npm test launch.test.ts

# Run tests with coverage
npm run test:coverage

npm test metadata.test.ts
```

**Note**: Metadata tests make real API calls to devnet and require internet connection.

## Examples

### Complete Token Launch Flow with Metadata

```javascript
const { 
  generateMetadataUri, 
  launchToken, 
  setUrc, 
  mintToken 
} = require('@flipflop-sdk/node');

async function completeFlowWithMetadata() {
  const rpc = 'https://api.devnet.solana.com';
  const creatorKey = 'creator-base58-private-key';
  const minterKey = 'minter-base58-private-key';
  
  // 1. Generate metadata URI
  console.log('Step 1: Generating metadata...');
  const metadata = await generateMetadataUri({
    rpc,
    name: 'Demo Token',
    symbol: 'DEMO',
    description: 'A demonstration token with custom metadata',
    imagePath: './assets/demo-logo.png'
  });
  
  if (!metadata.success) {
    throw new Error(`Metadata generation failed: ${metadata.error}`);
  }
  
  console.log('Metadata URL:', metadata.metadataUrl);
  console.log('Image URL:', metadata.imageUrl);
  
  // 2. Launch token with metadata
  console.log('Step 2: Launching token...');
  const launch = await launchToken({
    rpc,
    name: 'Demo Token',
    symbol: 'DEMO',
    tokenType: 'standard',
    uri: metadata.metadataUrl,
    keypairBs58: creatorKey
  });
  
  console.log('Token launched:', launch.mintAddress.toString());
  
  // 3. Set URC
  console.log('Step 3: Setting URC...');
  const urc = await setUrc({
    rpc,
    mint: launch.mintAddress.toString(),
    urc: 'DEMO_CODE',
    keypairBs58: creatorKey
  });
  
  console.log('URC set:', urc.urc);
  
  // 4. Mint tokens
  console.log('Step 4: Minting tokens...');
  const mint = await mintToken({
    rpc,
    mint: launch.mintAddress.toString(),
    urc: 'DEMO_CODE',
    keypairBs58: minterKey
  });
  
  console.log('Mint successful:', mint.success);
  
  return {
    metadata: metadata.metadataUrl,
    mint: launch.mintAddress.toString(),
    urc: urc.urc,
    transaction: mint.data?.tx
  };
}
```

### Batch Operations with Metadata Validation

```javascript
async function batchMintWithValidation() {
  const imagePaths = [
    './assets/logo1.png',
    './assets/logo2.jpg',
    './assets/logo3.gif'
  ];
  
  // Validate all images first
  const validations = imagePaths.map(path => ({
    path,
    validation: validateImageFile(path)
  }));
  
  const validImages = validations.filter(v => v.validation.valid);
  const invalidImages = validations.filter(v => !v.validation.valid);
  
  if (invalidImages.length > 0) {
    console.warn('Invalid images found:');
    invalidImages.forEach(img => {
      console.warn(`- ${img.path}: ${img.validation.error}`);
    });
  }
  
  // Process valid images
  const metadataPromises = validImages.map((img, index) => 
    generateMetadataUri({
      rpc: 'https://api.devnet.solana.com',
      name: `Batch Token ${index + 1}`,
      symbol: `BT${index + 1}`,
      description: `Batch generated token ${index + 1}`,
      imagePath: img.path
    })
  );
  
  const metadataResults = await Promise.all(metadataPromises);
  console.log('Batch metadata generation results:', metadataResults);
  
  return metadataResults;
}
```

## Migration from CLI

### CLI to SDK Mapping

| CLI Command | SDK Function |
|-------------|-------------|
| `flipflop launch` | `launchToken()` |
| `flipflop set-urc` | `setUrc()` |
| `flipflop mint` | `mintToken()` |
| `flipflop display-mint` | `getMintData()` |
| `flipflop display-urc` | `getUrcData()` |
| **NEW** | `generateMetadataUri()` |
| **NEW** | `validateImageFile()` |

### Migration Example

**CLI usage:**
```bash
flipflop launch --name "MyToken" --symbol "MTK" --keypair-file ./keypair.json --rpc https://api.devnet.solana.com
```

**SDK usage:**
```javascript
const { generateMetadataUri, launchToken } = require('@flipflop-sdk/node');

// Generate metadata first (new capability)
const metadata = await generateMetadataUri({
  rpc: 'https://api.devnet.solana.com',
  name: 'MyToken',
  symbol: 'MTK',
  description: 'My awesome token',
  imagePath: './logo.png'
});

// Launch with metadata
const result = await launchToken({
  name: 'MyToken',
  symbol: 'MTK',
  tokenType: 'standard',
  uri: metadata.metadataUrl,
  rpc: 'https://api.devnet.solana.com',
  keypairFile: './keypair.json'
});
```

## Security

- Never commit private keys to version control
- Use environment variables for sensitive configuration
- Validate all inputs before SDK operations
- **Image Security**: Only upload trusted images, validate file types and sizes
- **Metadata Security**: Review generated metadata before using in production
- Consider using `Keypair.fromSeed()` for deterministic key generation
- Always verify transaction results before proceeding
- **Network Security**: Use HTTPS endpoints for all API calls

## TypeScript Support

Full TypeScript support with comprehensive type definitions:

```typescript
import { 
  LaunchTokenOptions, 
  LaunchTokenResponse,
  MintTokenOptions,
  MintTokenResponse,
  SetUrcOptions,
  SetUrcResponse,
