How To Add Harmony to Metamask: The Ultimate Step-by-Step Guide

Hey there crypto friend! Have you heard about the Harmony blockchain? It‘s one of the most exciting Layer 1 protocols out there.

In this complete guide, I‘ll show you step-by-step how to connect Harmony to your MetaMask wallet.

By the end, you‘ll be able to use the fast, secure and cheap Harmony network directly in MetaMask.

Let‘s get started!

What is Harmony and Why Should You Care?

Before we dive into the how-to, let me give you a quick rundown of what Harmony is and why it‘s worth your attention.

In short, Harmony is an Ethereum-compatible blockchain designed from the ground up to solve some of the biggest issues facing older chains like Ethereum itself.

I‘m talking about problems like:

Slow transaction speeds
Congestion and high gas fees
Poor scalability

Not fun right?

The brilliant minds behind Harmony looked at these limitations and said "There has to be a better way".

So they built a brand new protocol using an innovative consensus model called Proof-of-Stake (PoS) combined with sharding.

This allows Harmony to divide the network into separate "shards" that can process transactions quickly in parallel.

The end result?

Harmony can handle 10,000+ transactions per second!

That‘s orders of magnitude faster than Ethereum‘s measly 15 TPS.

And here‘s a look at how insanely fast and cheap sending crypto is on Harmony:

Blockchain	Avg. Transaction Time	Avg. Fee
Ethereum	1-5 minutes	$2 – $10+
Harmony	2-5 seconds	< $0.001

As you can see, you go from waiting minutes and paying a few bucks in fees on Ethereum…

To lightning fast transactions at a fraction of a penny on Harmony!

Beyond speed and fees, there are a few other cool features that make Harmony a next-gen blockchain you should know about:

Decentralized Applications – Harmony already has a thriving ecosystem of dApps for DeFi, NFTs, gaming and more.
Ethereum Compatibility – It uses the Ethereum Virtual Machine (EVM) so apps can migrate over easily.
Effective Proof-of-Stake – Its consensus is secure while also allowing everyday users to stake and earn rewards.
Fully Open Source – Harmony is built by a team of experienced engineers and cryptographers who believe in transparency.
Focus on Adoption – The team is laser-focused on making blockchain easy for the masses to use.

Now maybe you‘re wondering…

Why Should I Add Harmony to My MetaMask Wallet?

That‘s an excellent question friend!

There are a few killer reasons I recommend every crypto user connect Harmony to their MetaMask wallet:

1. Use Harmony‘s Fast and Cheap Transactions

Once linked to your MetaMask, you can send crypto back and forth on Harmony‘s network for pennies and near-instant settlement.

No more waiting minutes for Ethereum transactions to go through.

2. Access Harmony‘s Awesome dApps

There are already 100s of decentralized apps spanning DeFi, GameFi, SocialFi and more being built on Harmony.

You can only use them if you connect Harmony to your wallet.

3. Stake ONE Tokens and Earn Rewards

Staking lets you earn passive income on your crypto. Harmony offers 8-12% APY for staking its native ONE token. Again – only accessible via Harmony wallet.

4. Join Harmony‘s Governance and Voting

Harmony has an active on-chain governance system for voting on network upgrades. You can only participate with a Harmony wallet.

5. Pay Tiny Fees in ONE Token

To use Harmony dApps and pay network fees, you‘ll need the native ONE token which is only available on the Harmony blockchain.

As you can see, connecting Harmony to MetaMask opens up a whole new world of possibilities!

Now let‘s get to the meaty stuff…

Once entered correctly, click Save.

Step 5: Connect to Harmony Network

You can now select Harmony Mainnet from the network dropdown menu.

Click it to connect your MetaMask wallet to the Harmony blockchain!

And that‘s seriously all there is to it my friend. Told you it was simple!

Once connected, your wallet is setup to interact with anything on Harmony like dApps, ONE tokens and more.

Now let‘s look at what you can actually do…

Using Your MetaMask Wallet on Harmony

With your MetaMask wallet connected to Harmony, a whole new decentralized world of possibilities opens up to you!

Here are some of the cool things you can start doing:

Use Harmony dApps

There are already hundreds of dApps launched and in development on Harmony. These include:

Decentralized Exchanges – Swap tokens and provide liquidity to earn fees and rewards.
Yield Farming – Earn massive APY by lending crypto on DeFi protocols.
NFT Marketplaces – Create, buy and sell digital art and collectibles.
Blockchain Games – Play games where you truly own in-game assets as NFTs.
DAOs & Social Tokens – Join decentralized communities and participate in governance.

You can browse the ever-expanding list of Harmony dApps right here:

And remember – you can only access these dApps if your wallet is connected to Harmony!

Send & Receive Assets

You can send assets like ONE and other tokens to your MetaMask‘s Harmony address with instant settlement and microscopic fees.

You can also share your Harmony address to receive crypto from exchanges or other users.

Stake ONE Tokens

The ONE token helps secure Harmony‘s network via staking. Stakers earn rewards of ~8-12% APY for helping validate transactions.

After getting ONE, you can stake directly in MetaMask to start earning rewards on your balance.

Participate in Governance

Harmony has on-chain governance that lets ONE holders vote on platform upgrades, new feature proposals and more.

With your wallet linked, you can take part in shaping Harmony‘s future direction.

Pay Fees in ONE

To use Harmony and interact with its dApps, you‘ll need a small balance of ONE tokens to pay network fees.

ONE is the native "gas" token of Harmony, like how ETH powers Ethereum. Even tiny amounts are enough for most transactions thanks to the low fees.

So in summary, connecting Harmony supercharges what you can do with MetaMask. Exciting right?

Now let‘s cover some frequently asked questions for smooth sailing.
