# SDK Initialization

### Basic Setup

```typescript
import { initFerraDlmmSDK } from '@ferra-labs/dlmm'

const sdk = initFerraDlmmSDK({
  network: 'mainnet',
  fullNodeUrl: 'https://fullnode.mainnet.sui.io:443',
  wallet: '0x...' // Your wallet address
})
```

### Configuration Options

#### Required Parameters

| Parameter       | Type                     | Description                     |
| --------------- | ------------------------ | ------------------------------- |
| `network`       | `'mainnet' \| 'testnet'` | Target network                  |
| `fullNodeUrl`   | `string`                 | Sui RPC endpoint URL            |
| `senderAddress` | `string`                 | Default sender for transactions |

#### Network Configurations

**Mainnet**

```typescript
const sdk = initFerraDlmmSDK({
  network: 'mainnet',
  fullNodeUrl: 'https://fullnode.mainnet.sui.io:443',
  wallet: '0x...'
})
```

**Testnet**

```typescript
const sdk = initFerraDlmmSDK({
  network: 'testnet', 
  fullNodeUrl: 'https://fullnode.testnet.sui.io:443',
  wallet: '0x...'
})
```

**Custom RPC**

```typescript
const sdk = initFerraDlmmSDK({
  network: 'mainnet',
  fullNodeUrl: 'https://your-custom-rpc.com',
  wallet: '0x...'
})
```

### Error Handling

```typescript
try {
  const sdk = initFerraDlmmSDK({
    network: 'mainnet',
    fullNodeUrl: 'invalid-url',
    wallet: '0x...'
  })
} catch (error) {
  if (error.message.includes('Invalid RPC')) {
    console.error('Please check your RPC URL')
  }
}
```

### Best Practices

1. **Single Instance**: Create one SDK instance per app
2. **Error Handling**: Always wrap initialization in try-catch
3. **Network Matching**: Ensure wallet and SDK use same network
4. **RPC Selection**: Use reliable RPC providers for production
5. **Address Validation**: Validate sender address format
