The ZRX cryptocurrency is the native token of the 0x Project—an open-source protocol designed to facilitate peer-to-peer trading of ERC20 tokens on the Ethereum blockchain. Also informally referred to as OX Coin, ZRX powers a decentralized infrastructure that enables developers to build decentralized applications (DApps) with integrated exchange functionalities. By combining off-chain order relaying with on-chain settlement, 0x optimizes speed, security, and cost-efficiency in token swaps—making it a foundational building block in the decentralized finance (DeFi) ecosystem.
This article explores the core mechanics of the 0x protocol, ZRX tokenomics, use cases, and where to trade ZRX. We’ll also examine how 0x addresses critical challenges in digital asset trading while maintaining decentralization and user control.
Understanding the 0x Protocol and Its Role in DeFi
At its foundation, 0x is not a traditional centralized exchange but a protocol, meaning it’s a set of smart contracts deployed on Ethereum that standardize how ERC20 tokens are traded across platforms. The key innovation lies in separating order matching from settlement:
- Off-chain order relay: Buy and sell orders are broadcast off the blockchain, reducing gas costs and increasing transaction speed.
- On-chain settlement: Only the final trade execution occurs on the Ethereum blockchain, ensuring transparency and immutability.
This hybrid model allows DApps, wallets, and marketplaces to integrate seamless token swapping without building their own order books or liquidity pools from scratch.

Who Created 0x?
The 0x Project was co-founded by Will Warren, a former mechanical engineer with a focus on robotics and cryptography, and Amir Bandeali, a financial trading systems expert. Their vision was to create an open standard for decentralized exchange—similar to how HTTP powers the web—that could be freely used and extended by any developer.
Launched in August 2017, the project raised funds through an initial coin offering (ICO), distributing ZRX tokens to early supporters. Since then, 0x has evolved into one of the most widely adopted infrastructure layers in DeFi.
ZRX Token: Key Specifications and Supply Details
| Attribute | Information |
|---|---|
| Token Name | ZRX |
| Blockchain | Ethereum (ERC-20) |
| Total Supply | 1,000,000,000 ZRX |
| Circulating Supply | ~500,000,000 ZRX (as of 2025) |
| Launch Date | September 26, 2017 |
| Founding Team | Will Warren, Amir Bandeali |
ZRX serves two primary functions within the ecosystem:
- Governance: Token holders can vote on protocol upgrades, fee structures, and treasury allocations via decentralized governance mechanisms.
- Staking Incentives: Relayers (entities that host order books) can stake ZRX to earn a share of trading fees generated on their networks.
Unlike some protocols that charge usage fees in their native token, 0x does not require users to pay fees in ZRX—making it more accessible and user-friendly. Instead, ZRX derives value from governance rights and staking rewards.
How Does 0x Solve Real-World Trading Challenges?
Traditional centralized exchanges like Coinbase or Binance offer fast execution and high liquidity—but come with risks such as hacking, regulatory shutdowns, or custodial control over user funds. On the other hand, early decentralized exchanges (DEXs) like EtherDelta suffered from poor user experience, low liquidity, and slow transaction finality due to every action requiring on-chain confirmation.
The 0x Solution: Efficiency Without Compromise
- Improved Speed & Lower Costs
By moving order creation and matching off-chain, 0x drastically reduces network congestion and gas expenses. Users only pay Ethereum gas fees when they finalize a trade. - Liquidity Aggregation
DApps built on 0x can pull liquidity from multiple sources—including other DEXs and private market makers—enabling better price discovery and deeper markets. - Permissionless Innovation
Any developer can launch a marketplace or integrate token swaps using 0x’s API and smart contracts. This has led to widespread adoption in NFT marketplaces, DeFi dashboards, and crypto wallets. - Trustless Transactions
No third party holds your funds. Trades occur directly between wallets using smart contracts, eliminating counterparty risk.
Where Can You Trade ZRX Tokens?
ZRX is listed on major cryptocurrency exchanges globally, offering both spot and sometimes futures trading pairs against USD, USDT, BTC, and ETH.
While early listings included platforms like Binance shortly after its ICO—which contributed to rapid price appreciation—today’s investors have numerous secure options for buying and selling ZRX.
Popular exchanges for trading ZRX include:
- OKX
- Bybit
- KuCoin
- Uniswap (via decentralized wallet swaps)
- SushiSwap
Always ensure you're using reputable platforms with strong security practices. As with any digital asset investment, conduct thorough research before trading.
Frequently Asked Questions (FAQ)
Q: Is ZRX an ERC-20 token?
A: Yes, ZRX is built on the Ethereum blockchain using the ERC-20 standard, making it compatible with all major Ethereum wallets and DeFi applications.
Q: What is the maximum supply of ZRX?
A: The total supply is capped at 1 billion tokens. Approximately half are currently in circulation, with the remainder allocated for ecosystem development, team incentives, and community rewards.
Q: Can I stake ZRX tokens?
A: Yes, users can stake ZRX to participate in protocol governance and earn rewards by supporting relayers who operate decentralized marketplaces powered by 0x.
Q: How does 0x differ from Uniswap?
A: While both facilitate token swaps, Uniswap uses automated market maker (AMM) models with liquidity pools, whereas 0x supports order-book-based trading with off-chain matching. Many AMMs actually use 0x behind the scenes for cross-platform liquidity routing.
Q: Is the 0x protocol secure?
A: The core smart contracts have undergone multiple audits by leading cybersecurity firms. Additionally, being open-source allows continuous community review and improvement.
Q: Do I need ZRX to use 0x-powered apps?
A: No. End users don't need to hold ZRX to swap tokens on applications using the 0x protocol. However, developers and stakers benefit from holding and using ZRX for governance and fee sharing.
Why 0x Matters in the Future of Digital Assets
As blockchain technology matures, interoperability becomes crucial. The 0x protocol plays a vital role by enabling seamless asset exchange across platforms—whether it's stablecoins, utility tokens, or NFTs. With growing integration into wallet interfaces like MetaMask Swap and DeFi aggregators like Matcha (which is built directly on 0x), its influence continues to expand.
Moreover, as Ethereum scales through layer-2 solutions like Arbitrum and zkSync, 0x has adapted by deploying its protocol across multiple chains—enhancing speed and reducing costs even further.

This multi-chain expansion ensures that ZRX remains relevant in a fragmented but increasingly interconnected crypto landscape.
Final Thoughts: ZRX as Infrastructure, Not Just a Token
ZRX may not grab headlines like newer meme coins or high-yield tokens—but its value lies in its foundational role in DeFi infrastructure. Rather than chasing short-term trends, 0x focuses on long-term utility: enabling trustless, efficient, and scalable token exchange for developers and users alike.
For investors interested in the backbone of decentralized finance—not just speculative assets—ZRX represents a compelling opportunity rooted in real-world application and sustainable design.
Whether you're a developer integrating decentralized trading into your app or an investor evaluating protocol-based cryptocurrencies, understanding what ZRX is, how it works, and why it matters offers valuable insight into the evolving crypto economy.
