If you’re a fan of the decentralization movement, then you’re probably already using or at least familiar with the Ethereum blockchain. And if you’re using Ethereum, then there’s a good chance you’re using MetaMask – one of the most popular Ethereum wallets around.
But what if you want to move beyond the testnet and start using Ethereum’s mainnet? In this article, we’ll show you how to do just that.
First, a few words about why you might want to use mainnet over testnet. While testnets are great for experimentation and testing out new features, they’re not always reliable.
Mainnet, on the other hand, is the “real deal” – the version of Ethereum that actually handles real value.
So if you’re ready to take the plunge into mainnet, here’s how to add it to your MetaMask wallet.
1) Open MetaMask and click on the network dropdown in the top-left corner.
2) Select “Custom RPC” from the list of options.
3) Enter the following URL into the “New RPC URL” field: https://mainnet.infura.io/v3/YOUR-INFURA-PROJECT-ID
Be sure to replace “YOUR-INFURA-PROJECT-ID” with your actual Infura project ID. If you don’t have one, you can create a free Infura account here.
4) Enter “Ethereum Mainnet” in the “Network Name” field.
5) Click “Save & Use in Browser Extension”.
That’s it! You should now be connected to Ethereum mainnet in MetaMask. You can confirm this by checking the network dropdown – it should now say “Ethereum Mainnet”.
One last thing to keep in mind – since mainnet deals with real value, be sure to take extra care when sending transactions. MetaMask will warn you about this when you try to make a transaction on mainnet – just be sure to double-check that everything is correct before hitting “Confirm”.
