ETH Telegram Mini App NextJS Starter Kit

Getting Started

This starter kit helps you create a mini application integrated with Ethereum and Telegram. Follow the steps below to set up and run the project.

Prerequisites

Ensure you have the following installed on your machine:

• Node.js (v16 or higher)
• npm or Yarn
• ngrok or localtunnel

Setup Guide

1. Clone the repository or click on the "Use this template" button:

   git clone https://github.com/HAPPYS1NGH/rabble-tg-mini-app-nextjs-js

2. Navigate to the project directory:

   cd rabble-tg-mini-app-nextjs-js

3. Create a .env or .env.local file in the root directory:

   Obtain the WalletConnect project ID from WalletConnect.

   WALLET_CONNECT_PROJECT_ID=<your_wallet_connect_project_id>

4. Install dependencies:

   Using npm:

   npm install

   or using yarn:

   yarn install

5. Start the development server:

   Using npm:

   npm run dev

   or using yarn:

   yarn dev

6. Open your web browser and navigate to http://localhost:3000 to view the application.

Exposing Your Local Server

To test your application within Telegram, you need to expose your local server using a tunneling service like ngrok or localtunnel.

Using ngrok

1. Install ngrok if you haven't already:

   npm install -g ngrok

2. Expose your local server on port 3000:

   ngrok http 3000

3. Note the generated public URL (e.g., https://abc123.ngrok.io).

Using localtunnel

1. Install localtunnel if you haven't already:

   npm install -g localtunnel

2. Expose your local server on port 3000:

   lt --port 3000

3. Note the generated public URL (e.g., https://abc123.loca.lt).

Registering Your Bot on Telegram

1. Open Telegram and search for BotFather.

2. Register a new bot by using the /newbot command and follow the prompts to choose a name and username.

3. While in BotFather, set the /setmenubutton and select your bot, then paste the proxy link.

4. Now you can see a small button next next to the chat which will bring up the Mini App.

Interacting with Contracts

This starter kit provides hooks from Wagmi v2 for interacting with smart contracts on the Arbitrum network. You can use these hooks to read and write data to contracts.
