0x serves as an infrastructure protocol designed to facilitate the seamless trading of ERC20 tokens and various assets across multiple blockchains, including Ethereum, without the need for centralized intermediaries. It functions as a decentralized exchange protocol. This decentralized exchange capability is achieved through a set of open-source, publicly auditable smart contracts that collaborate to create a versatile, frictionless trading protocol that developers can effortlessly integrate into their products. Numerous companies developing web3 applications, such as wallets, decentralized exchanges (DEXes), portfolio trackers, and others, utilize the 0x protocol. It is adopted by hundreds of developers for their projects. Since its inception, the protocol has facilitated over $200 billion in trading volume. Powering the protocol is an ERC20 governance token called ZRX. ZRX holders are able to engage in protocol governance, wielding direct influence over protocol changes and the community treasury.
