How to participate in Carboneum Crowdsale

We have come a long way to this moment and we are amazed by all the support from the community. Now that we are soon to start our Crowdsale, we are happy to provide a Crowdsale participation guide before the big day. Remember, with the partnership with ICON in place, you can participate using ICX (ERC-20) AND ETH!

Carboneum Whitelist

Whitelisting will REMAIN OPEN during the crowdsale, but please note that it takes approximately 1 day for the KYC verification to be completed.
If you have not whitelisted yet, please complete your KYC at https://carboneum.io/ico

Only whitelisted addresses of those participants who have passed KYC and have their ETH addresses inside the Crowdsale contract will be able to participate.

For Pre-sale investors, your addresses will be whitelisted in our Crowdsale contract automatically.

***Your ETH Address MUST be an ERC-20 compatible wallet. Do not send from an exchange or smart contract. Failure to do so may result in token loss (how to register your wallet with Carboneum)***

Carboneum Crowdsale

Crowdsale starts on 25th June 2018, 10am (GMT+7) and will conclude when all C8 tokens are sold, or after 8th July 2018, 10am (GMT+7), whichever occurs first.

Please contribute ONLY to the address linked to Carboneum website (https://carboneum.io). Carboneum will never post Crowdsale contract address via Telegram, Telegram admins, Social media or emails.

Individual cap for Crowdsale is 50 ETH and no minimum contribution. All C8 Tokens will be sold on a first come, first serve basis.

Crowdsale rate :

1 ETH = 6000 C8
1 ICX (ERC-20)= 22 C8

Recommended gas limit: 100,000

Gas price: Submit a transaction with a reasonable gas price should ensure the transaction gets through. Please refer to https://ethgasstation.info/ for an appropriate gas price to set.

You will be able to access the address for the Carboneum Crowdsale contract on https://carboneum.io as the Crowdsale starts. Please ensure beforehand that you check an address in Etherscan to ensure contract creator address starts with 0x5023.
