• Token Storage: Upon making a transaction via crowdsale, tokens will be stored in a LinkedCHAIN wallet.
• Admin Role: Entities that complete a transaction via crowdsale are marked as admins.

Token Distribution and Validation:

Crowdsale Information

The crowdsale functionality allows companies to purchase Hyrd(HYD) tokens, which are used within the LinkedCHAIN ecosystem to validate and endorse job histories. The exchange rate for the crowdsale is 1 unit to 0.5 Ether. Participants can purchase tokens at this rate and use them to validate employment records.
