To participate in the protocol or simply to Product-share, means to purchase one or more products from the PRODUCTSHARE Marketplace and share the links to the purchased products on social media. The first time someone buys the same item using your product-share link (ie by clicking the product link you shared), the protocol rewards you automatically with cash back for that specific product. Cashback reward funds are transferred immediately to your PS wallet and can be instantly withdrawn to any US debit card or PayPal account.
