Hi there! If you are reading this article you have contributed in the first phase of our ICO, and you need to reclaim your Ether to your Ethereum Wallet.

This procedure can be carried out from July 31 at 12:00 GMT.

There are 2 main methods with which you can get back the amount invested. The first and easiest one is through Metamask, the second and more complicated one is through myEtherWallet.

Depending on how you contributed, go to section:

  1. If you invested through a MetaMask Wallet
  2. If you invested through another wallet and you want claim back the ETH using Metamask by importing the wallet (THE EASY WAY)
  3. If you invested through another MyEtherWallet and want to claim back the ETH through MyEtherWallet (THE HARD WAY)

1. If you invested through a MetaMask Wallet

If you have contributed to our project in Phase 1 using a Metamask wallet, you will find a Claim Refund button on our Dashboard.

Clicking the Claim Refund button will open the Metamask interface to authorise the refund transaction.

It will look like this:

Now click the Submit button and metamask will send the refund request to the Ethereum blockchain.

A link to will appear, where you’ll be able to see confirmation of the transaction.

2. Import Wallet into MetaMask (EASY WAY)

If you have used other wallets such as MyEtherWallet and you have the JSON file or the private key of your wallet, you can import it in Metamask.

First of all you have to install the extension/addon at one of the following links, depending on which browser you are using.




In this example we’re going to use Chrome. First click on the “Add to Chrome” button.

Now click “Add extension”

In the top-right corner of your browser you should now see the MetaMask fox logo. Click on it.

The extension will ask you for a password. Choose an effective password and click on Create.

Now you will be given a set of random words that will allow you to recover your account should you lose the password. Save them as a file or write them down and store them safely.

Now you have correctly installed Metamask, and you are ready to import your own wallet.
