# Web3 Marketplace on Polygon

## App Idea

Create a marketplace for selling regular goods or services; this is _not_ an NFT-marketplace. We'll start by using a [standard marketplace template](https://showcase-store.directual.app) and then proceed to integrate authentication via [MetaMask](https://metamask.io/). All financial transactions will conducted in MATIC, the [Polygon](https://polygon.technology) cryptocurrency.
