### Regtest Environment Management
- Mine blocks to confirm transactions
- Generate new regtest coins for testing
- Simulate network activity
- Test with different fee rates and confirmation settings

## Prerequisites

- Node.js v22 or later
- Bitcoin Core running in regtest mode
- Caravan (optional, for UI-based multisig wallet management)



## Installation

Install globally using npm:

```bash
npm install -g caravan-x
```


## Quick Start

1. Make sure Bitcoin Core is running in regtest mode
2. Run the command:

```bash
caravan-x
```

This will start the interactive menu interface.


## Installation for development

1. Clone the repository:
   ```
   git clone https://github.com/yourusername/caravan-regtest-manager.git
   cd caravan-regtest-manager
   ```

2. Install dependencies:
   ```
   npm install
   ```

3. Build the project:
   ```
   npm run build
   ```

4. Link the CLI globally (optional):
   ```
   npm link
   ```

## Usage

### Interactive Mode

Start the interactive terminal UI:

```
npm start
```

Or if you've linked it globally:

```
caravan-x
```


## Configuration

The default configuration is stored in `~/.caravan-regtest/config.json`. You can modify this file to change:

- Bitcoin Core RPC connection settings
- Directory paths for Caravan wallet configurations
- Key storage locations


## Command Line Usage

You can also use various commands directly:

```bash
# List all wallets
caravan-x list-wallets

# Create a new wallet
caravan-x create-wallet

# List Caravan wallets
caravan-x list-caravan

# Create a new Caravan multisig wallet
caravan-x create-caravan

# Fund a wallet with regtest coins
caravan-x fund-wallet --wallet <wallet-name>

# Create a new PSBT
caravan-x create-psbt

# Sign a PSBT with a wallet
caravan-x sign-psbt --file <psbt-file> --wallet <wallet-name>

# Mine blocks
caravan-x mine --blocks 10 --wallet mywallet

# Start blockchain visualization
caravan-x start-visualization
```

Run `caravan-x --help` to see all available commands.


## Development

### Running in Development Mode

```
npm run dev
```

### Linting

```
npm run lint
```

### Running Tests

```
npm test
```

## Security Considerations

This tool is intended for **regtest and development purposes only**. It should never be used with real funds or on mainnet because:

1. Private keys may be stored in plain text
2. Security is not hardened for production use
3. It focuses on developer convenience over security best practices
