Setting up a Metamask Wallet
Setup your Metamask account following the instructions.
Once your Metamask setup is complete, you should be redirected to your newly created Ethereum wallet:
If you click on the "three dots" button below your account name - in our case Account 1 - a popup will appear with your account address. It should look similar to the example below:
In the top right you should see a dropdown menu with Main Ethereum Network selected. With this option, you are able to interact directly with the main Ethereum blockchain.
If you click on it, a selection of other networks will be shown:
Drop down menu for selecting the network.
Before launching a project (or dapp) on the main Ethereum network, it is good practice to deploy a version to an Ethereum test network (like Rinkeby) or on other main networks (like Polygon or Harmony) with low-cost fees to save on costs for transaction fees.
The main reason for using a test net ETH is that it can be obtained without having to pay real money. This gives developers and the community a chance to iron out any problems before real money is involved.
Finally, you can also interact with private Ethereum networks by selecting Localhost 8545. Private in this case doesn't mean more secure. It just means that the nodes are not connected to the main or test network nodes. Perfect for rapid experimentation and testing.
