Summary
Many users look for a way to add the Harmony network to MetaMask, a widely used cryptocurrency wallet, because it offers a convenient and reliable way to manage their Harmony ONE tokens and interact with the blockchain. While MetaMask is primarily designed for the Ethereum network, it also supports other Ethereum Virtual Machine (EVM)-compatible blockchains like Harmony. By manually entering Harmony’s network details to add to MetaMask, users can seamlessly send, receive, and store ONE tokens. It also enables them to connect with decentralized applications (dApps) built on the Harmony ecosystem. Since Harmony supports smart contracts, users can participate in staking directly through MetaMask, making it a versatile tool for managing their activities on the network.
Can I Add Harmony to MetaMask?
Yes, just like any other EVM-compatible network, you can add Harmony to MetaMask as well. MetaMask is a Web3 wallet designed to work with all Ethereum Virtual Machine (EVM) compatible networks, and since Harmony falls under this category, adding Harmony to MetaMask is a straightforward process. Once the network is added, MetaMask can be used to hold $ONE tokens and explore the Harmony ecosystem, including various dApps built on the network.
About Harmony Network
Harmony is a Layer 1 blockchain built to address the scalability challenges that networks like Ethereum often encounter. It operates on a Proof-of-Stake (PoS) consensus mechanism, which is more energy-efficient and allows users to stake tokens to help secure the network. A key feature of Harmony is state sharding, a method that divides the network into smaller sub-chains.
This approach boosts transaction speed and lowers costs, enabling Harmony to process up to 2,000 transactions per second with a finality time of just two seconds, meaning transactions are confirmed almost instantly. The native token, ONE, is used for transaction fees, staking, and governance within the network. Harmony’s architecture is designed to strike a balance between scalability, security, and decentralization, aiming to solve the blockchain trilemma.
Add Harmony to MetaMask
The process of adding the Harmony network to MetaMask follows the same steps as adding any other network. You’ll need the correct RPC details and will have to manually configure the network in MetaMask. However, there’s also a simpler alternative. In this section, we’ll cover both options.
Add Harmony to MetaMask Manually
The first method involves using MetaMask’s custom network feature, where you manually input the Harmony network’s RPC details. These settings are essential for connecting to the right network, so it’s important to verify them through Harmony’s official documentation.
Using incorrect or outdated RPC details; often scattered across various sources, can lead to connecting with the wrong network and potentially exposing your wallet to risk. To make it easier, we’ve provided the accurate Harmony network configuration in the next section, along with a step-by-step guide to help you add it to MetaMask safely.

Add Harmony to MetaMask Automatically
You can now add the Harmony network directly through the MetaMask Chrome extension. To make the process easier, a one-click option is available that lets you quickly add Harmony to MetaMask. Simply click the “Add Harmony Network to MetaMask” button, review the network details, and confirm the action to add it to your wallet.
Bottom Line
If you’re looking to explore the Harmony ecosystem or simply want a secure way to manage your $ONE tokens, taking a few minutes to add Harmony to MetaMask is a smart move. It opens up access to dApps, staking options, and low-cost transactions—all from a wallet you likely already use. Whether you go with the manual method or the one-click approach, adding the network helps you get more out of your Web3 experience.
FAQs
1. Can I use Harmony on MetaMask Mobile App?
Yes, Harmony can be added and used on the MetaMask mobile app just like on the desktop extension. The steps are slightly different due to the mobile UI, but you can still manually enter the network details or use deep-linking to auto-add the Harmony network. Once added, you’ll be able to send, receive, and manage ONE tokens directly from your phone.
2. Why am I seeing a “Chain ID already exists” error when adding Harmony?
This error usually means that you’ve already added Harmony under a different name or it’s conflicting with a testnet or a custom chain using the same Chain ID. To resolve it, go to your MetaMask settings > Networks, look for any custom network with Chain ID: 1666600000, and either edit or delete it before adding the correct Harmony mainnet details.
3. Can I bridge assets from Ethereum to Harmony using MetaMask?
Yes! You can use MetaMask with Harmony-compatible bridges such as Horizon Bridge to move assets like ETH, USDC, or DAI from Ethereum to Harmony. After bridging, those assets will appear as wrapped tokens on the Harmony network and be usable across its ecosystem. Make sure you switch to the Harmony network in MetaMask before interacting with these assets.
4. Do I need $ONE tokens in MetaMask to pay gas fees on Harmony?
Absolutely. Just like ETH is used for gas on Ethereum, $ONE is required for transaction fees on Harmony. Before interacting with any dApps or sending tokens on Harmony, ensure your MetaMask wallet has a small amount of ONE to cover these fees. You can get $ONE via centralized exchanges and then withdraw directly to your MetaMask wallet address on Harmony.
5. Can I use MetaMask to stake $ONE tokens on Harmony?
Technically, staking requires interacting with Harmony’s official staking dashboard, which doesn’t directly integrate with MetaMask. However, some third-party tools and dApps allow MetaMask wallet connection for staking, or you can delegate $ONE tokens via Harmony’s validator system using other compatible wallets that support staking natively.
