Import into MetaMask

Step 1: Download Metamask

Step 2: Aquire your seed phrase from One Wallet

  • You should already have your seed phrase written down safely from initial setup. If you don’t then its not the end of the world as you can still get you private key.

Step 3: Aquire your private key from One Wallet

  • This is needed if you already have a metamask wallet setup. It is also recomeneded to store this key in addition to your seed phrase.
  • To aquire this private key, you need to first select your wallet from the menu button on the top right of One Wallet. Make sure the tick is next to your wallet.
  • Then click the menu button once again and select Export Private Key. Enter your wallet password and write down your key.

Step 4: Import into MetaMask

Version 1 Walkthrough

  • As this is a fresh metamask install you can click ‘import wallet’. Select Get Started followed by Import Wallet.
  • Enter your Seed/Mnemonic phrase inside the Secret Recovery Phrase. Enter a new password and check the Terms of Use box. After you finish you can Import your wallet.
  • If the entered seed phrase was correct you will be greeted with a congratulations page.

Version 2 Walkthrough

  • If you are importing your wallet to MetaMask that already has an account ( maybe you have been playing in Defi ), then you cannot use your Seed/Mnemonic phrases to import your wallet. YOU CAN ONLY USE A PRIVATE KEY.
  • Click on the account icon displayed at the top right.
  • Click on Import Account.
  • Enter your private key as exported from One Wallet.
  • Click Import
  • If it is done correctly you will see the new account show up and you can switch between accounts using the Account Icon on the top right.

Step 5: Add Harmony Network to Metamask

  • A full guide from the harmony docs can be found here but I will break it down for you below.
  • Click on the network dropdown (top center). It will likely already say Etherium Network.
  • Click on Add Network and enter the following information.
  • Network Name: Harmony Mainnet
  • New RPC URL:
  • Chain ID: 1666600000
  • Currency symbol (optional): ONE
  • Block Explorer URL (optional):
  • Click Save.
  • You will now see the Harmony Network in the dropdown at the top. Make sure this is selected to be able to 1) see you assets and 2) interact with the harmony blockchain.

Step 6: Sending and receiving ONE

  • You need to aquire the ONE version. Paste the 0x Metamask address into explorer and then click the ONE tab at the top. You will see the address convert itself to the ONE format. Copy this into your origin wallet. Please send a test amount first.
  • You need to aquire the 0x version. Paste the exchange ONE address into explorer and click the ETH tab at the top. Copy this address into Metamask and make sure that the gas is set to 30 gwei on Metamask. Please send a test amount first.
