# Deployment and Testing

To deploy and test the Telegram bot, follow these steps:

## Deployment

1. **Set Environment Variables**:
   * Create a `.env` file in the project root.
   * Add the necessary variables such as `TELEGRAM_BOT_TOKEN`, `ETH_RPC_SEPOLIA`, etc.
2. **Deploy to a Cloud Platform**:
   * Choose a cloud service like Heroku, Vercel, or any platform that supports Node.js.
   * Deploy the bot along with the Express server.
3. **Set Webhook**:
   * Configure the bot’s webhook using the `/setWebhook` endpoint.
   * Example:

     ```bash
     axios.get(`${TELEGRAM_API}/setWebhook?url=${WEBHOOK_URL}`);
     ```

## Testing

1. **Local Testing**:
   * Run the bot locally with:

     ```bash
     npm start
     ```
   * Interact with the bot via Telegram to test commands and workflows.
2. **Webhook Testing**:
   * Ensure the webhook is correctly set and responding to Telegram messages.
   * Use tools like ngrok to expose your local server to the internet for testing.
3. **Blockchain Interaction Testing**:
   * Test transactions on a testnet (e.g., Sepolia).
   * Verify that contributions and withdrawals are processed correctly and securely.
