# Configuration

## Wallet Configuration

```javascript
const config = {
  network: 'MAINNET' // 'MAINNET', 'SIGNET', or 'REGTEST'
}

const wallet = new WalletManagerSpark(seedPhrase, config)
```

## Account Creation

```javascript
// WalletAccountSpark is created by the WalletManagerSpark
// It does not take configuration parameters directly
const account = await wallet.getAccount(0) // Get account at index 0
```

## Configuration Options

### Network

The `network` option specifies which Spark network to use.

**Type:** `string`

**Values:**

* `"MAINNET"` - Spark mainnet (production)
* `"SIGNET"` - Spark signet (testing)
* `"REGTEST"` - Spark regtest (local development) - [Get test funds](https://app.lightspark.com/regtest-faucet)

**Default:** `"MAINNET"`

**Example:**

```javascript
const config = {
  network: 'REGTEST' // Use REGTEST for development
}
```

## Network Configuration

The wallet can be configured for different Spark networks:

```javascript
// Mainnet configuration
const mainnetConfig = {
  network: 'MAINNET'
}



// Regtest configuration
const regtestConfig = {
  network: 'REGTEST'
}
```

## BIP-44 Derivation Path

Spark uses the [BIP-44](https://docs.wdk.tether.io/resources-and-guides/concepts#bip-44-multi-account-hierarchy) coin type 998, resulting in derivation paths like:

* `m/44'/998'/0'/0/0` for MAINNET account index 0
* `m/44'/998'/0'/0/1` for MAINNET account index 1
* `m/44'/998'/2'/0/0` for SIGNET account index 0
* `m/44'/998'/3'/0/0` for REGTEST account index 0

The path follows the pattern `m/44'/998'/{networkNumber}'/0/{index}` where:

* `998` is the coin type for Spark
* `networkNumber` is 0 for MAINNET, 2 for SIGNET, or 3 for REGTEST
* `index` is the account index

This ensures compatibility with standard [BIP-44](https://docs.wdk.tether.io/resources-and-guides/concepts#bip-44-multi-account-hierarchy) wallets while using Spark's unique coin type identifier.

## Complete Configuration Example

```javascript
import WalletManagerSpark from '@tetherto/wdk-wallet-spark'

// Create wallet manager with configuration
const seedPhrase = 'abandon abandon abandon abandon abandon abandon abandon abandon abandon abandon abandon about'
const wallet = new WalletManagerSpark(seedPhrase, {
  network: 'MAINNET'
})

// Get accounts (no additional configuration needed)
const account0 = await wallet.getAccount(0)
const account1 = await wallet.getAccount(1)

// Clean up when done
wallet.dispose()
```
