Connecting MetaMask to a Private Hyperledger Besu Network on Different Computers
As a user of the Hyperledger Fabric blockchain platform, you’re probably familiar with the convenience of MetaMask, a popular wallet for Ethereum and other cryptocurrencies, for managing 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 set up this connection.
Prerequisites
Before we begin, make sure that:
- You’ve 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: Install MetaMask on Computer B
Install MetaMask on Ubuntu computer (B):
- 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 Private Hyperledger Besu network on computer B
- Open a new terminal on your Ubuntu computer (B).
- Type "nodemon" and press Enter.
- Use cd to navigate to your project directory.
- Run the following command to connect to your Private Hyperledger Fabric network:
metamask connect --network
Replace with the actual name of your private Hyperledger Fabric network.
Step 5: Verify the connection
Once you have connected to the network, make sure that your MetaMask wallet has been successfully connected. You can do this by checking Blockchain Explorer or using themetamask’ command-line tool.
Troubleshooting Tips
- If you encounter problems, make sure your Ubuntu and Windows computers are running on separate 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.
By following these steps, you should now be able to connect your MetaMask wallet on your Windows computer (Computer A) to the private Hyperledger Besu network running on your Ubuntu computer (Computer B). Happy blockchain exploration!
