Reward Programs or Promotions are designed to encourage users to engage with the fiat-to-crypto on-ramp service by offering them financial incentives. These incentives can take the form of cashback on transactions, discounts on fees, or loyalty points that can be redeemed for future transactions. The primary purpose of this feature is to enhance user acquisition and retention by making the service more attractive and cost-effective for users, ultimately driving higher transaction volumes and fostering a loyal customer base.
