History

0x is building a protocol to enable the creation of decentralized exchanges for the Ethereum blockchain in order to facilitate permissionless transfers of values. Decentralized exchanges have the potential to offer advantages over centralized systems such as real-time settlement, reduced counterparty risk, censorship-resistant transactions, and transparent technology. Initially, the project will focus on the exchange of ERC20 with plans to build capabilities to allow for the exchange of any Ethereum based asset.

0x is not managing a decentralized exchange itself but is instead building the infrastructure to enable the creation of these platforms. Rather than using on-chain order books, 0x relies on “relayers” to manage order books through off-chain messaging, while transactions are settled on the blockchain based on quotes from the off-chain messaging service. Comparatively, this reduces costs related to updating orders and offers a faster exchange process.

The team has also created a variety of products using 0x. Asset Swapper enables other decentralized finance projects to automatically find liquidity, pass it onto their smart contracts and fill orders at the best prices. 0x Instant offers a simple crypto purchasing experience for any application or website. 0x Launch kit provides tools to launch an exchange or marketplace.
