Openfort has integrated Arbitrum One and Nova and has extended support for Orbit. This integration is set to enhance the gaming industry by tapping into the unique features of Arbitrum's distinct platforms, bringing diverse benefits to game developers and players alike.

Arbitrum's three platforms, Nova, One, and Orbit, offer an array of advantages for gaming and decentralized applications.
- Arbitrum Nova is suited for gaming, metaverse, and socialfi projects, enabling instant confirmation and less than 0.01 USD transactions with minimal trust assumptions, courtesy of the AnyTrust model that posts data offchain using a Data Availability Committee (DAC).
- Arbitrum One, being fully EVM compatible and built on Optimistic Rollup technology, is apt for “GameFi” use cases.
- Arbitrum Orbit stands out with its customization features and future upgradeability, making it an adaptable choice for high-demand games.

With the integration of Arbitrum One and Nova, and the support for Orbit, Openfort enhances the gaming environment. Game developers have more resources at their fingertips to craft engaging and cost-effective gaming experiences, and players can anticipate smoother gameplay with reduced transactional challenges.

Joan Alavedra, Co-Founder of Openfort, shared his thoughts: “Integrating Arbitrum's diverse platforms with account abstraction technology from Openfort significantly uplifts the gaming ecosystem. We are making it more accessible, scalable, and enjoyable for the gaming community.”

Jack Fitzpatrick of the Gaming Partnerships team at Offchain Labs shared the following: “Account Abstraction serves to address many of the pain points associated with onchain UX today. Solutions like Openfort allow developers to take advantage of features like sponsored gas, auto-signing transactions, and even social login with account recovery options. It’s a major upgrade for the end user and an important step in the road to mass adoption. We’re excited that Arbitrum gaming teams have access to a reliable solution across the entire Arbitrum stack in Openfort.”

Telegram Mini-Apps have emerged as a powerful tool for developers to reach over 950 million monthly active users directly within the Telegram messenger. These lightweight applications, built using web technologies like HTML, CSS, and JavaScript, offer a seamless and integrated user experience without the need for separate downloads or installations.

The recent milestone of the TON blockchain surpassing 1 billion transactions, with half of this volume recorded in just the last three months, underscores the growing popularity and potential of Telegram Mini-Apps. This rapid growth is driven by innovative applications across various categories, including games, management tools, and utilities.

### Key Benefits of Telegram Mini-Apps:

1. **Instant access**: Users can engage with Mini-Apps directly from a Telegram chat, bypassing traditional app distribution challenges.
2. **Seamless integration**: The familiar Telegram interface reduces friction and enhances user engagement.
3. **Bot interaction**: Leverage Telegram Bots for automated experiences and interactive features.
4. **Massive user base**: Tap into Telegram's existing pool of 950 million monthly active users.
5. **Monetization opportunities**: Explore various revenue streams through in-app purchases, subscriptions, or advertising on the TON blockchain.

## How to build a Telegram mini-app with Openfort

In this tutorial, we'll walk through the process of building a web3 Telegram mini app using Openfort's SDK. **The full mini-app repository can be found [here](https://github.com/openfort-xyz/sample-telegram-mini-app-Embedded-Wallet)**.

You can also test it out in your Telegram app by chatting with **"@OpenfortMiniAppBot"**.

By the end of this guide, you will have a fully functioning web3 Telegram mini app that allows users to:

- Authenticate using their Telegram account
- Generate a [non-custodial smart wallet](https://www.openfort.xyz/docs/guides/dashboard/custom-auth/telegram-mini-app)
- Mint NFTs directly from Telegram
- View their wallet information

Note: There are two methods of authentication with telegram. [Telegram auth](https://www.openfort.xyz/docs/guides/dashboard/social-login/auth-telegram) requires the botUsername as an OAuth2 authentication flow with telegram, similarly to how you login with Google with an access/refresh token returned. This method goes through the screen you have seen with the Continue with Telegram button.

The other method, [telegramMiniApp](https://www.openfort.xyz/docs/guides/dashboard/custom-auth/telegram-mini-app), uses the signed initDataRaw from the telegramSDK available in the mini app as third party authentication. It does not have any kind of refresh token since telegram is in charge of issuing new authentications. This method can be used directly from the mini app without requiring interaction with the user as he is already authenticated with the mini app.

So the telegram method can be used for example in a normal browser like firefox, chrome or unity or another platform. **The telegramMiniApp method is specially designed to work in mini apps an it's the one used in this guide.**

---

### Prerequisites
- Openfort account
- Telegram account
- Node.js and yarn installed
- ngrok or similar tunneling service for local development

## Step 1: Create a Telegram Mini App with BotFather
1. Add BotFather to your Telegram
2. Enter the command `/newbot` (new bot must be created first before creating an app)
3. Choose and enter a name and username for your bot
4. You will be given an access token - go to [Openfort authentication providers](https://dashboard.openfort.xyz/players/auth/providers) and add the `bot_token` in the Telegram Mini-app section.
5. Create a new mini app with the command `/newapp`
6. Select your bot and follow the prompts for app name, description, and photo
7. When asked for the URL, you'll need your ngrok URL (we'll set this up later)

## Step 2: Project Setup

1. Clone the repository:
```bash
git clone https://github.com/openfort-xyz/sample-telegram-mini-app-embedded-wallet
cd sample-telegram-mini-app-embedded-wallet
```

2. Create environment files:
```bash
# In /next-app directory
cp .env.example .env

# In /telegram-bot directory
cp .env.example .env
```

3. Configure environment variables:

In `/next-app/.env`:
```env
NEXT_PUBLIC_TELEGRAM_BOT_TOKEN=<your-bot-token>

NEXT_PUBLIC_OPENFORT_PUBLISHABLE_KEY=<from-openfort-dashboard>
NEXT_PUBLIC_OPENFORT_SHIELD_PUBLISHABLE_KEY=<from-openfort-dashboard>
NEXT_PUBLIC_OPENFORT_POLICY_ID=<your-policy-id>
NEXT_PUBLIC_OPENFORT_CHAIN_ID=<your-chain-id>
NEXT_PUBLIC_OPENFORT_CONTRACT_ID=<your-contract-id>

OPENFORT_SECRET_KEY=<from-openfort-dashboard>
OPENFORT_SHIELD_SECRET_KEY=<from-openfort-dashboard>
OPENFORT_SHIELD_ENCRYPTION_SHARE=<from-openfort-dashboard>
```

In `/telegram-bot/.env`:
```env
BOT_TOKEN=<your-bot-token>
FRONTEND_APP_ORIGIN=<your-ngrok-url>
```

## Step 3: Set Up Public URL
1. Install ngrok: `npm install -g ngrok`
2. Start ngrok: `ngrok http 3000`
3. Copy the HTTPS URL provided by ngrok
4. Update your Mini App URL in BotFather with this URL
5. Add the URL to `FRONTEND_APP_ORIGIN` in `/telegram-bot/.env`

## Step 4: Configure Openfort
1. Create an account on [Openfort Dashboard](https://dashboard.openfort.xyz/)
2. Create a new application
3. Get your API keys (Standard and Shield)
4. Create a new Asset and Policy
5. Add all IDs and keys to your environment variables

## Step 5: Install Dependencies and Run

1. Install dependencies:
```bash
# In /next-app directory
cd next-app && yarn install

# In /telegram-bot directory
cd ../telegram-bot && yarn install
```

2. Start both services:
```bash
# In /next-app directory
yarn dev

# In /telegram-bot directory (new terminal)
yarn dev
```

## Step 6: Test the Integration

1. Open your Telegram bot
2. Send the `/start` command
3. Click the "Launch App" button
4. The mini app should open and:
   - Authenticate you using your Telegram account
   - Generate a non-custodial wallet
   - Allow you to mint an NFT

## Key Components

### Telegram Bot
The bot is configured in `/telegram-bot/src/bot/features/openfort.ts`:
```typescript
feature.command('start', async (ctx) => {
  const keyboard = new InlineKeyboard().webApp(
    'Launch App',
    `${process.env.FRONTEND_APP_ORIGIN}/login/telegram`,
  )
  return ctx.reply('Click to launch.', { reply_markup: keyboard })
})
```

### API Routes
The Next.js app includes three main API routes:

1. `/api/createAuthConfig` - Configures Telegram Mini App authentication
2. `/api/createEncryptionSession` - Creates encryption session for non-custodial wallet
3. `/api/mintNft` - Handles NFT minting

### Main App Page
The main app logic is in `/next-app/src/app/login/telegram/page.tsx`, handling:
- Telegram authentication
- Wallet configuration
- NFT minting interface

For more detailed information, refer to the [repository README](https://github.com/openfort-xyz/sample-telegram-mini-app-embedded-wallet).

## Conclusion

You now have a working Telegram mini app that:
- Authenticates users via Telegram
- Creates self-custodial smart wallets
- Allows users to mint NFTs
- Handles sponsored transactions securely through Openfort's infrastructure

The mini app provides a seamless web3 experience without requiring users to leave Telegram, making it more accessible to mainstream users.
