ZRX is associated with the 0x protocol, an open-source infrastructure that enables the decentralized exchange of digital assets on the Ethereum blockchain. The 0x protocol facilitates peer-to-peer trading of ERC-20 tokens without the need for intermediaries or centralized exchanges. The ZRX token serves multiple purposes within the 0x ecosystem. It can be used for decentralized governance, allowing token holders to participate in decision-making processes such as protocol upgrades and fee structures. Additionally, ZRX tokens can be staked to earn rewards and receive a portion of the trading fees generated by the 0x protocol. As more transactions occur on the 0x protocol, the value of ZRX tokens may increase alongside the protocol's expansion.
