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.
