Eg. If your invited friend uses 100 BABY to mint 1 vBABY, he/she will get 1 vBABY, and you will get 0.1 vBABY at the same time. The vBABY referral reward is unredeemable but can earn the same benefits as the regular vBABY; it will disappear when you or your invited friends partially or completely redeem vBABY to BABY again.
