# Cashback Rewards

1. Advertisers create a campaign by specifying the cashback percentage, budget, minimum spend, time period, and conditions for the promotion. Once the campaign is funded with CRN tokens matching the budget, it goes live. 
2. Chainrewardz's AI engine then analyzes the campaign details to find suitable publishers within the network.
3. Publishers eligible to participate can set their own margin within the limits defined by the advertisers. For instance, if an advertiser sets a 10% cashback, a publisher might choose to offer 3% to customers and keep the remaining 7%.
4. When users make purchases and redeem the provided code, the publisher receives CRN tokens. If the tokens run low, the advertiser must top up the balance, or the campaign will be paused until the end date.
