0x Protocol


0x is an open protocol that facilitates peer-to-peer exchange of digital assets on the Ethereum blockchain. 0x is open source, free to use, and provides a drop-in exchange solution for developers to build on top of. Developers use 0x protocol to build decentralized exchanges (DEXs), marketplaces for digital collectibles, and to integrate exchange functionality into wallets.

0x protocol overview

In 0x Protocol, orders are transported off-chain over any arbitrary medium, massively reducing gas costs and reducing blockchain bloat. Relayers help broadcast orders and collect a fee each time they facilitate a trade. Anyone can build a relayer.

The simplest example of a Relayer is a website allowing users to create, discover and fill orders. The Relayer must build out a UI and host a backend database to provide this functionality.
