MetaMask is the most popular crypto wallet on the planet. Because of this, there are many who wish to know how to work and navigate through it. One particular thing you can do is add networks, such as Harmony, to MetaMask.

It is actually very easy to add networks to MetaMask, which is what we will show you how to do in this article. Not only that, but we will give you exact instructions on how to add the Harmony network to MetaMask through your browser and on your mobile device.

Additionally, we will give you some bonus information about Harmony and MetaMask in later sections.

If you are new to the MetaMask network, we suggest checking out our extensive article focusing on what the wallet does, how it works, and many other topics surrounding it. We explain in great detail why you might need a MetaMask wallet, how secure is it, and how to create your first account.

Leaving that aside, let’s focus on the topic at hand and get right into it.

Why Add Harmony Network to MetaMask?

There are a couple of notable reasons why you might want to connect Harmony to MetaMask. Here are some of them:

  1. Ability to explore and access dApps on Harmony.
  2. Testing different features.
  3. Holding ONE token.
  4. Security and safety

How to Harmony Network to MetaMask – Extension/Browser

If you are using your browser, there are two main ways to add the Harmony network to your MetaMask wallet.

  1. Using Chainlist.
  2. Manually through MetaMask

1. Adding the Harmony network to MetaMask is very easy if you do it through the official Chainlist website. Once you open Chainlist, you need to search for Harmony. You will get 8 different results. Depending on your needs you can select a different network. We assume that you are looking for the main Harmony network, which is going to be the first option in the top-left corner.

2. Adding Harmony Network through MetaMask manually is a bit longer a process. First, you need to open your MetaMask browser extension. Click on the current Mainnet in the top-middle section. By default, this should say “Ethereum Mainnet”.

This will open a drop-down menu, where you need to click on “Add Network”. Here, you need to manually enter the network name, RPC URL, Chain ID, currency symbol, and block explorer URL.

See the sections below for an in-depth guide on how to do both. We also have a section, where we help you add the Harmony network to MetaMask on mobile devices.

How To Add Harmony Network to MetaMask – Chainlist

  1. Open Chainlist.
  2. Search for Harmony and click “Add Network”
  3. Confirm the action in MetaMask

1. Open Chainlist

Open the Chainlist official website. It should look a little something like the image below.

step 1, open chainlist landing page

Chainlist is an explorer website where you can look for addresses and information.

Once you open the website, proceed with the next step in our guide.

2. Search for Harmony & Click “Add Network”

Once you open Chainlist, use the search bar at the top and type in Harmony. You will see 8 different results. Depending on your needs you can add a different network. However, the main one you are probably looking for is the one with ChainID: 1666600000, which is the first result. This is where you need to click on the “Add Chain” button. See the image below for visualization.

step 2, chainlist website, search for harmony and click add network

Furthermore, before clicking on that, make sure you log in to your MetaMask wallet account.

Once you complete this step, you can proceed with the next one.

3. Confirm the Action in MetaMask Pop-Up

Because MetaMask wallet allows you to connect to different dApps using your browser, you will see a pop-up once you click on “Add Chain”. Once that’s done, you will need to confirm the action twice before the network is added to your MetaMask wallet.

Additionally, do not worry if an error appears, as this is the case when adding any network to MetaMask.

Once that’s done, you will have the Harmony network added to MetaMask. Also, it will automatically switch to it once you add it.

About Harmony

Harmony is a fast and scalable crypto network that enables decentralized applications to run efficiently. The Harmony team is focused on building a platform that is secure, stable, and scalable, with the goal of becoming the foundation for the next era of social and economic collaboration.

In order to achieve this, Harmony utilizes a unique consensus algorithm that is based on PoS (Proof-of-Stake) and PBFT (Practical Byzantine Fault Tolerance). This allows the network to achieve near-instant finality, while also being more energy-efficient than other networks.

In addition, Harmony utilizes sharding to improve scalability, meaning that the network can handle a large number of transactions without sacrificing speed or security. Currently, Harmony is one of the most active crypto networks, with a growing community of developers and users.

Many believe that Harmony has the potential to become the leading platform for decentralized applications in the future.

About MetaMask Wallet

MetaMask is a crypto wallet that comes in the form of a browser extension (Chrome, Firefox, Brave, and Edge) or a mobile application (iOS and Android). It is well-known for being the best software wallet for ERC-20 tokens. In fact, the wallet only supports Ethereum-based cryptocurrencies and NFTs.

Nowadays a lot of people use MetaMask to connect to different decentralized applications (dApps). Most notably, people connect their MetaMask to PancakeSwap. There, they exchange Ethereum, for example, for another cryptocurrency that is not available in other crypto exchanges.

It also is a simple entry point to the world of DeFi. DeFi stands for decentralized finances, which is a term used to describe companies that look to provide open, permissionless, interconnected financial services. These services are usually lending and borrowing crypto, as well as other crypto-oriented banking services.

Most NFT marketplaces such as OpenSea support MetaMask. At the beginning of the crypto boom back in 2021, MetaMask got the spotlight as the most popular and easy-to-use crypto wallet to buy NFTs.
