The 0x Protocol is a foundational technology in the decentralized finance (DeFi) ecosystem, built to facilitate the peer-to-peer exchange of digital assets on the Ethereum blockchain. Its native token, ZRX, plays a central role in both governance and network operations. This guide delves into how 0x works, its use cases, and the utility of the ZRX token.
What is 0x (ZRX)?
0x is an open-source, decentralized protocol designed to power a tokenized world where all value can flow freely. It serves as the infrastructure that allows developers to build decentralized exchanges (DEXs) and other applications that require token swapping functionality. By utilizing a shared set of smart contracts, 0x enables users to trade various Ethereum-based tokens across a pooled liquidity network without needing to trust a central intermediary.
The protocol’s technology leverages a hybrid approach, combining state channels and Automated Market Makers (AMMs). State channels allow transactions to be processed off-chain, dramatically reducing the gas fees associated with on-chain Ethereum transactions. AMMs, on the other hand, use algorithmic pricing and liquidity pools to facilitate trades automatically when specific market conditions are met.
The ZRX token is integral to this ecosystem. It is used for governance, granting holders voting rights on proposals that dictate the protocol's future development. Voting power is proportional to the amount of ZRX held. The total supply of ZRX is capped at 1 billion tokens.
A Brief History of 0x
0x was co-founded by Will Warren and Amir Bandeali in late 2016. The project successfully conducted an Initial Coin Offering (ICO) in 2017, raising $24 million with support from prominent venture capital firms like Polychain Capital and Pantera Capital.
The token distribution was clearly outlined from the start: 50% of the total ZRX supply was sold to public investors during the ICO. Another 15% was allocated to the core development team, 15% to an external project development fund, 10% to the founding team, and the final 10% was reserved for early backers and advisors. Today, over three-quarters of the maximum supply is in active circulation.
Over the years, the 0x team has launched several key products to bolster adoption. These include 0x Instant, a tool for applications to offer a simple crypto purchasing experience, and the 0x Launch Kit, which provides the necessary components for anyone to start their own exchange or NFT marketplace.
How Does the 0x Protocol Work?
At its core, 0x is a permissionless protocol that enables the trading of Ethereum-based tokens, including ERC-20 and ERC-721 (NFT) standards. It operates through a network of independent actors called "relayers."
Relayers host off-chain order books, which are collections of open buy and sell orders. They use the 0x protocol to create their own DEXs and aggregate liquidity from the entire market. This system helps users find the best possible price for any given trading pair. While relayers never take custody of user funds, they earn fees for their matchmaking services.
0x employs a sophisticated API that scans prices across the entire DeFi landscape, including major DEXs like Uniswap and SushiSwap. This provides users with a seamless trading experience by sourcing the most optimal prices. Furthermore, the protocol uses special bridge contracts to tap into the liquidity pools of on-chain DEXs.
With the launch of version 3, 0x introduced a staking mechanism. Liquidity providers (market makers) can now earn ETH rewards for supplying depth to the network. ZRX holders who may not be active traders can still participate by delegating their tokens to these market-making pools to earn a share of the rewards.
For those looking to build their own trading venue, the 0x Launch Kit offers a peer-to-peer (P2P) protocol for OTC trading of DeFi tokens, ensuring secure and direct settlements between parties with faster processing times.
What is the ZRX Token Used For?
The ZRX token has two primary functions within the 0x ecosystem: governance and fee payment.
Governance: ZRX is a governance token. Holders can propose and vote on changes to the 0x protocol parameters, such as fee structures or technical upgrades. This creates a decentralized and community-led framework for the project’s evolution.
Fee Payments: The token is used to pay trading fees to the relayers that operate the off-chain order books. This creates a circular economy within the 0x network, where usage drives demand for the token.
The protocol’s flexibility also allows it to support a wide array of assets, from standard cryptocurrencies to non-fungible tokens (NFTs) representing unique digital or real-world items like art, collectibles, and real estate.

Frequently Asked Questions
What is the 0x Protocol?
0x is an open-source protocol that provides the underlying infrastructure for decentralized trading on the Ethereum blockchain. It allows developers to build applications that can access a shared network of liquidity, enabling users to trade tokens directly from their wallets without a centralized intermediary.
How is the ZRX token used?
ZRX is primarily used for governing the 0x protocol. Holders can vote on proposals to guide its development. It is also used to pay fees to the relayers that host order books and provide liquidity to the network.
What is the total supply of ZRX?
The maximum supply of ZRX is capped at 1 billion tokens. A significant majority of these tokens are already in circulation, with the remainder allocated for staking rewards and ecosystem development.
How does 0x generate liquidity?
0x aggregates liquidity from a vast network of relayers and on-chain DEXs. Its smart order routing technology scans multiple sources to find the best price for a trader, creating a deep and efficient market.
Can 0x be used for NFT trading?
Yes, the protocol supports the trading of both fungible tokens (ERC-20) and non-fungible tokens (NFTs or ERC-721), making it a versatile tool for the entire digital asset ecosystem.
Is 0x a good investment?
As with any cryptocurrency, investing in ZRX carries risk. Its value is tied to the adoption and usage of the 0x protocol. Researching the project's fundamentals, market position, and the broader DeFi landscape is essential before making any investment decision.
