Aug 14, 2017 · 4 min read

Note: This is a step by step guide on how to exchange your Ethereum into YUP so you can get ready to become a Crowdholding supporter during our Pre-ICO / ICO. If you do not know how to create a wallet or purchase Ethereum, please go back to part 1 (how to create a wallet) and part 2 (how to purchase ETH and transfer it to your wallet). If you wish to learn more about our company or our ICO click here.

During the Crowdholding ICO, which starts on the 1st of November at 10AM (GMT) you will be able to exchange your Ethereum for YUP.

Step 1

To become a Crowdholding supporter, you will have to log into your wallet. Because in this guide we created the wallet with myetherwallet, this guide will use this wallet as an example. Other wallets work in a very similar way, so this guide will still be useful if you have a wallet with a different application.

So log into your wallet on MyEtherWallet, and start a new transaction by going to the “Send Ether & Tokens” tab. You will need to unlock your wallet first by entering your Keystore FIle and your password.

Once you have logged into your wallet, go to our website, where after 10AM (GMT) on the 1st of November you will see our public address. An example is below.

Simple click on the “get tokens” button, accept the terms and conditions and our wallet address will appear. Copy this public address (the ox number) and go back to your wallet. Since you have already unlocked you will be presented a page where you can copy and paste an address in the “To address” box.

Select the amount of ETH you wish to exchange. In the “Gas Limit” field enter 400,000 gas (this is a small fee needed by Ethereum to process your transaction) Once you have double checked the public address and the amount, click the “Generate Transaction” button. Once you click the “Generate Transaction” button, another button will appear, click on the “Send Transaction” if you are ready to complete the exchange.

Congratulations! You have just become a Crowdholder supporter!

Step 2

After you have completed the transaction, you can check to see if the transaction was successful.

You can use the service Etherscan to check your wallet’s transaction history. On MyEtherWallet, you can find the link to your Etherscan page under “Transaction history” on the left of the page.

Part 3

Below are some instructions on how to view the YUP token in your ERC20-compatible wallet of choice.

The YUPIE token contract has the following attributes:

Download your private key on exodus (they have a video to show you how to do this), and then go to myetherwallet, view wallet info, put in your private key. Then go to add custom token, and put in for the address 0x0F33bb20a282A7649C7B3AFf644F084a9348e933 with the token name (YUP) and 18 decimals and you should be able to see your Yupies.
