In the Holo ICO, purchasing HoloTokens is as simple as sending ETH to our ICO smart contract’s address from a whitelisted Ethereum address.

However, we’ve made a site that makes this whole process less mystifying and more secure. Visit https://ico.holo.hostwhere our ICO site will:

  • provide you with information regarding the supply and availability of the day’s tokens,
  • inform you of how many tokens you’ve purchased,
  • tell you how many tokens are reserved for you,
  • calculate exactly how much ETH to send in order to buy a specific number of HoloTokens,
  • automatically generate transactions so that sending ETH is as easy as authentication and then the click of a button, and
  • help you maintain the security of your purchase.

We recommend everyone purchases HoloTokens through our ICO site using MetaMask.

This friendly little guide will walk through how to purchase HoloTokens using the site.

Prerequisites

Make sure you have these things in the bag before following this guide to purchase HoloTokens

1. Registration & whitelisting

You must be registered and whitelisted, with your identity verified and your Ethereum address synchronized with our on-chain whitelist, before attempting to purchase HoloTokens. If you have not been whitelisted yet, get that out of the way first and then come back: Holo ICO whitelisting

Your ETH address must be synchronized with our whitelist before you send us any ETH

2. Wallet & ETH

You’ll need an Ethereum wallet with ETH in it to purchase HOT. Check out our tips and resources on setting up an Ethereum wallet in our knowledge base article.

IMPORTANT: Make sure that the Ethereum wallet that you’re purchasing HoloTokens with is ERC20 token-compatible. Many exchange wallets such as Coinbase are not compatible with ERC20 tokens like HoloTokens. For example, if you purchase HoloTokens using an address from Coinbase, your HoloTokens will be gone forever. Use a wallet like MetaMask or MyEtherWallet, or use a hardware wallet.

Coinbase and other exchanges aren’t compatible with HoloTokens. Use MetaMask or MEW instead.

Purchasing HoloTokens

IMPORTANT: More than likely there will be various phishing scams across the internet pretending to be Holo and trying to trick you into sending ETH to them instead of us. Be extremely careful and alert about where you’re sending ETH. Always make sure that you’re on our actual ICO site by checking the URL in your address bar. It should say:

https://ico.holo.host

If it says anything else than that, stop what you’re doing and contact Holo support immediately.

Now that those prerequisites and security warnings are out of the way, you’re ready to buy some HoloTokens!

You can purchase HoloTokens by simply sending ETH to our smart contract address:

  1. Visit our ICO site and scroll to the “Ethereum Address” section.
  2. Read the security information and confirm that the address displayed in the green box is equal to the addresses in the listed confirmation locations.
  3. From your whitelisted wallet, send the amount of ETH you’d like to participate with to the confirmed ICO contract address. Use a high gas limit because our contract uses a multi-step transaction. 155,000 should be good.

But,

we strongly recommend you use our ICO site along with the MetaMask browser extension (available for Google Chrome, Firefox, and Opera) in order to buy HoloTokens more easily and securely. If you have the Mist browser, you can also use that. Here’s how to use MetaMask and our site to purchase HoloTokens:

Step 1: Install MetaMask. CryptoCompare has a snazzy guide on how to set up and use MetaMask.

MetaMask, installed, shows up as a fox mask icon in your browser

Step 2: If your whitelisted wallet is not a MetaMask wallet (if it’s a MyEtherWallet or a hardware wallet) you’ll need to import it into MetaMask. If you originally set up your wallet in MetaMask, skip to Step 3.

  • Click on MetaMask’s fox mask icon in your browser and unlock if prompted.
  • Click on the switch profile icon which looks like a person with two arrows circling it.
  • Click on “Import Account”.
  • Enter either your Ethereum account’s private key, or your JSON file and password, both of which you should have saved or stored somewhere safe when you created your account.

Step 3: Once your whitelisted address is loaded into MetaMask, make sure MetaMask is unlocked and visit our ICO site. You should now see a cheery green message stating that your address is whitelisted.

Step 4: Scroll to the “Purchase HoloTokens (HOT)” section of the page.

Step 5: Use the slider or the input fields to select how much ETH to send or how many HOT to purchase. Once you are satisfied with your selection, click the “Send ETH” button to open a MetaMask window with your transaction already filled out.

Make sure that “Gas Limit” is set to 150000, and “Gas Price” is set to 4

Step 6: Make sure to click “Submit” in the transaction window after reviewing that the fields are correct.

Congratulations!

You’ve now purchased HoloTokens. It’s really that easy! They’ll be sent to your ETH address immediately, and you can look at them by following the instructions in our About HoloTokens guide.

And remember, if you have trouble, you are always welcome to visit our customer support knowledge base or ask questions on our chat community to get advice or guidance. And if you’ve checked those resources and the issue you’re encountering is not addressed, send an email to our friendly support team: help@holo.host. We’re always here to help.
