Connecting 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 convenience of using 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 will walk you through the steps to achieve this connection.

Prerequisites

Before we begin, make sure that:

• You have installed MetaMask on both computers.

• The Private Hyperledger Fabric network is set 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 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 the Cordova CLI).

• Start the Cordova service: cordova start

• Install Node.js (version 14 or later): 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 the 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 computer B

• Open a new terminal on the Ubuntu computer (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 

Replacewith the actual name of your Hyperledger Fabric private network.

Once you have connected to the network, verify that your MetaMask wallet has successfully connected. You can do this by checking blockchain explorer or by using the command line toolmetamask`.

Troubleshooting Tips

• If you encounter problems, make sure that your Ubuntu and Windows computers are running on different networks.

• Check the network settings on both operating systems to make sure they are configured correctly.

• If you are using a VPN, try disabling it and reconnecting to the network.

After following these steps, you should now be able to connect your MetaMask wallet on a Windows computer (computer A) to the Hyperledger Besu private network running on an Ubuntu computer (computer B). Happy blockchain exploration!
