What is Harmony
Harmony is an Ethereum layer 2 solution, that offers fast transaction speed and low gas fees. Harmony began development in 2018 on the Binance Launchpad, and went live May of 2019. Harmony supports fungible and non-fungible tokens and runs on the Ethereum Virtual Machine. Harmony is the home of crypto game DeFi Kingdom.
Harmony To Metamask
In order to add Harmony, we will need to add it’s network RPC to Metamask. This will allow Metamask to send and receive transactions from the blockchain.

-
Open Metamask
Open Metamask and click the drop-down menu in the very top center of the window. This is the network selection menu. At the bottom of the menu you will see an add network button. Click this button.
-
Enter RPC Details
A new window will pop up. In this window we will enter the network settings for Harmony, including the Network name, RPC, Chain ID, Currency Symbol and Block Explorer URL. Not all of these details are mandatory, but filling them all in will make Metamask easier to use later.
The following table has the details for the Harmony network. You can copy them into the corresponding fields. There are multiple options for the RPC and Chain ID fields; choose only one when you enter the information. Periodically the RPC can become congested and you may need to shift to an alternate RPC. If this happens, replace the existing RPC address with one of the alternates provided below.
Network Name Harmony Mainnnet New RPC URL https://api.harmony.one
https://s1.api.harmony.one
https://s2.api.harmony.one
https://s3.api.harmony.oneChain ID (use number only)
Shard 0: 1666600000
Shard 1: 1666600001
Shard 2: 1666600002
Shard 3: 1666600003Currency Symbol (Optional) ONE Block Explorere URL (Optional) https://explorer.harmony.one/ The currency symbol ONE, is the token that will be used for gas fees. The explorer URL allows you to check the status of Harmony network transactions directly from Metamask. We recommend adding both.

Add Missing Coins
Once the network has been added it should auto-detect your coins. If this does not happen, you can manually add coins to Metamask. In the Assets tab, scroll down to the bottom of the list and click on import tokens.
A new window will open asking for the token contract address, token symbol, and the number of decimal places. Token addresses can be found on the Harmony Block Explorer.
You can search for any HRC20 token by its symbol, name, or address. Simply type it into the search bar. Once found, copy the address of the token and cut and paste it into Metamask. Enter the symbol, choose the number of decimal places and click add token.

Hi I’m Mike, an active crypto investor DeFi enthusiast and crypto miner. I have been involved in crypto since March of 2021 and in DeFi since May 2021.
I’m also an avid outdoor adventurer!
Shard 3 cannot be added to Metamask. I have been trying for over a month. Is there a reason for this? I have funds in Shard 3 I need to send back to Shard 0. Please advise how to go about doing this. Thanks.
Hi Wyatt,
Try using the Harmony chrome wallet. It has cross shard capability and should allow you to transfer from shard 3 to shard 0. For the most part you should keep all your funds on shard 0 as that is where all the apps and exchanges are on.
