ZRX
The ZRX token uses the 0x protocol (a decentralized exchange, or DEX, infrastructure) residing on the Ethereum blockchain to enable the trade of Ethereum-based tokens and assets using smart contracts.
ZRX is the native token for the 0x protocol. It is considered reliable and flexible, leading to its vast adoption amongst decentralized exchanges (DEXs) like Maker, Dharma, Augur, etc. The protocol allows a swift exchange of cryptocurrencies safely and affordably. Using the 0x protocol, developers can also create Ethereum-based decentralized cryptocurrency exchanges.
