Tradepal is made up of a core principle and multiple functionalities. Central to the experience on Tradepal is the social and interest graphs of the user, commonly called the Cluster of Friends, which includes both Facebook friends on Tradepal and Tradepal friends. The functionalities evolve around a User Profile that comprises the user’s Items, the Friends’ and Friends of Friends’ listings, the user’s Wishes and individual Carbon Savings Calculator. Both Profiles and Listed Items can be shared internally with Tradepal friends, or externally with Facebook friends and Twitter followers. Users can trade with peers by instantly buying an item using the Buy Now option or by sending an offer using either cash and/or barter Users can additionally communicate with one another using messaging, item comments, or online chat. The concept of trust is based on both the use of Facebook identities as Tradepal identities as well as a rating system derived from all transactions conducted on the platform. All payments are conducted through PayPal's Adaptive Payments and benefit from PayPal’s Buyer’s Protection.
