It is a protocol that allows you to build a decentralized exchange (DEX) where you can buy and sell Ethereum-based virtual currencies. A decentralized exchange (DEX) is a next-generation exchange that is operated without a central administrator and unattended using blockchain technology, and features no risk of hacking because the DEX itself does not hold any assets.

It is a next-generation exchange that operates unattended using blockchain technology, with no assets in the DEX itself, so there is no risk of hacking. 0x increases liquidity by aggregating the trading information of various DEX for Ethereum-based currencies, and lowers transaction fees by conducting all but the main processing off the blockchain.

0x is a mechanism to increase liquidity by aggregating and managing the trading volume and number of trades of each DEX and matching trades. In addition, when a DEX is built using the 0x protocol, information can be shared.

In the case of a token A, the token B can be exchanged directly with the token A. This eliminates the need to use a base currency and eliminates fees.

By integrating into a virtual currency wallet app, users can easily exchange their own currency for other currencies handled by 0x.

It can be purchased on Binance, etc.
