In this study, we built a smart contract model based on online haggling in determining the purchase of a product. Buyers and sellers haggle with each other for the products they want via online the seller web app. Finally, we propose a smart contract design model using online haggling, which can help provide decision-making in determining the appropriate price from the seller and buyer agreement.
