A referrer is someone who receives a campaign link and shares it with others using 2key referring function. When receiving a 2key campaign, you are presented with two options:

1- Participate
 Participate means taking any action for the campaign that you are interacting withthe type of participation  is worded differently according to the type of campaign - Open link, buy a ticket, buy tokens, donate …

2- Refer and Earn

When selecting the second option, “Refer and Earn”, you become a campaign referrer and can earn rewards. 2key system automatically includes your referral in the campaign smart contract and you can track all sharing and participating activity downstream from your account’s Referral tab.
When one of the people with whom you shared the link, or another referrer brought in by you, participates, you earn the portion of the reward due to you.

Your share of the reward is calculated according to the reward split model defined in the smart contract, which you can see in the right column of the SmartLink content.


  • Some PPC SmartLinks are shared with no reward, just to enable tracking influence and increase Web3.0 adoption.

  • Donation campaigns also carry Gratitude Tokens, which have no monetary value. This might be in addition to crypto rewards or not, depending on the Donation campaign smart contract. If monetary rewards are offered, sharers have the built-in option to donate their reward.
