Metamask: How to link metamask on another computerA(windows) to a private hyperlink on another computerB(ubuntu)

Connect MetaMask to a private Hyperledger Besu network on different computers

As a user of the Hyperledger Fabric blockchain platform, you are probably familiar with the practical use of MetaMask, a popular wallet for Ethereum and other cryptocurrencies, to manage your digital assets. But what if you want to connect your MetaMask wallet to a private Hyperledger Besu network running on a different computer? In this article, we’ll walk you through the steps to make that connection.

Prerequisites

Before we begin, make sure that:

  • You have MetaMask installed on both computers.
  • The Hyperledger Fabric private network is up and running on your Ubuntu computer (Computer B).
  • Your MetaMask wallet is properly configured for Ethereum (or the cryptocurrency you want to use) on your Windows computer (Computer A).

Step 1: Download and install Node.js

Since MetaMask requires a node with JavaScript support, download and install the latest version of Node.js from the official website.

Step 2: Set up MetaMask on computer B

On the Ubuntu computer (B), follow these steps to set up MetaMask:

  • Open a terminal.
  • Type “sudo npm install -g cordova” (if you are using Cordova CLI).
  • Start the Cordova service: “cordova start”
  • Install Node.js (version 14 or higher): “sudo apt-get update && sudo apt-get install nodejs”

Step 3: Configure MetaMask on computer B

  • Open a terminal.
  • Type “npm install -g metamask” (if you are using Metamask CLI).
  • Start the Metamask service: metamask start
  • Configure your Ethereum wallet settings in the Metamask CLI by running: metamask config set --network

Step 4: Connect to the Hyperledger Besu private network on machine B

  • Open a new terminal on the Ubuntu machine (B).
  • Type nodemon and press Enter.
  • Navigate to your project directory using cd.
  • Run the following command to connect to your Hyperledger Fabric private network:

metamask connect --network

Replace with the actual name of your Hyperledger Fabric private network.

Step 5: Verify the connection

After connecting to the network, verify that your MetaMask wallet is successfully connected. You can do this by checking the blockchain explorer or using the command line tool “Metamask”.

Troubleshooting tips

  • If you are experiencing issues, make sure your Ubuntu and Windows computers are running on separate networks.
  • Check the network settings in both operating systems to make sure they are configured correctly.
  • If you are using a VPN, try disabling it and reconnecting to the network.

By following these steps, you should now be able to connect your MetaMask wallet on the Windows computer (Computer A) to the Hyperledger Besu private network running on the Ubuntu computer (Computer B). Have fun exploring the blockchain!
