# Shoppers Shoppers are the customers who buy goods or services from merchants and pay them in exchange for goods/services they are purchasing. Shoppers are the ones who will have to connect their crypto exchange and bank to make payments using RocketFuel's solution. A shopper can choose to sign up and have a RocketFuel account or can also be a guest shopper. A regular shopper has their own shopper portal once they sign up, and they can check/track their transactions, request refunds, and set default exchange and currency for their iframe. A guest shopper does not have these functionalities. A shopper can sign up on RocketFuel by visiting the link [https://shopper-sandbox.rocketfuelblockchain.com. ]() ![RocketFuel Shopper Portal](/files/dvgjKWqrSsd4Jg4wjfvq) ![](/files/OOcylgk9aFHpYpGLcvKD) --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
