MetaMask SDK Node.js Demo

This is a simple Node.js application that demonstrates how to interact with the MetaMask wallet using the MetaMask SDK and gather user input using the enquirer library.

Prerequisites

Before you can run this demo, you need to ensure that you have the following installed:

Installation

  1. Clone this repository to your local machine:

    git clone <repository_url>

  2. Navigate to the project directory:

    cd sdk-nodejs-demo

  3. Install the project dependencies:

    yarn install

Usage

  1. Start the application:

    yarn start

    The application will prompt you to select an action from a list of options using the enquirer library.

  2. After selecting an action, the application will dynamically determine the appropriate Ethereum method and execute it using the MetaMask SDK.

  3. The results of the Ethereum method calls will be displayed in the console.

Configuration

  • MetaMask SDK Options: You can configure MetaMask SDK options in the options object in the index.ts file. This includes specifying the dapp metadata, logging settings, and customizing modal text.

  • Ethereum Methods: To add more Ethereum methods or customize the behavior of existing ones, you can modify the start function in the index.ts file. For example, you can add a new condition to handle a specific action.

Available Actions

  • getAccounts: Retrieve the user's Ethereum accounts.
  • getChainId: Get the current Ethereum chain ID.
  • signMessage: Send an Ethereum transaction (customize parameters as needed).
  • getBalance: Get the balance of an Ethereum address (customize parameters as needed).
  • Other actions: You can extend the list of available actions as needed.
