It will be a built-in tool on an e-commerce website to reward customers with cryptocurrencies using smart contracts. It aims at small businesses that cannot spend cashback on every purchase and want to create a temporary, short-term cashback campaign on their website. People buy regular items using fiat; if they participate in a cashback campaign defined by the shop owner, at the end of the campaign period, they will receive crypto as cashback automatically.
It's not a third-party app like the Lolli extension, and it's not cash back on every purchase. It can enable the shop owner to define their own customized, built-in crypto cashback campaign on their website.
main features: low fee, customizable, automatic payment at specific date and time, and integrated into the website.
