Transaction history and ratings are stored on Ethereum so the data is decentralized, publicly viewable, and verifiable. We believe sellers should be able to take their history and reputation with them wherever they sell - and buyers should be able to verify who they are dealing with, even when buying outside of established marketplaces.
Here is my selling profile as an example: https://replin.com/geehwan
Click on reviews and you can see the Ethereum transactions of completed Replin sales.
Currently in beta, we are targeting places like IG, Twitter, FB, Reddit, where we realized lots of people buy and sell stuff already.. mostly to escape fees from eBay etc, but also because it's more fun.
Our team currently runs Listia (YCS09) and the two products are integrated. Sellers can bring their entire Listia selling history to Replin and all future Listia sales are also synced to Replin. We extracted the basic buy/sell flow of a typical p2p marketplace transaction and built it into Replin for transactions outside of marketplaces. Long term we think people should be able to transact safely anywhere, while owning their own reputation and data.
Would really love any feedback, especially if you sell online or on eBay etc.. thank you!
