The world of decentralized finance (DeFi) continues to evolve, and at the heart of this transformation lies ZRX, the native token of the 0x protocol—a foundational piece of infrastructure enabling seamless, peer-to-peer trading of ERC-20 tokens on the Ethereum blockchain. Designed as an open standard for decentralized exchanges (DEXs), the 0x protocol empowers developers to build scalable, interoperable DeFi applications with built-in trading capabilities.
Whether you're new to DeFi or a seasoned crypto enthusiast, understanding ZRX and its underlying technology is essential for navigating the future of decentralized trading.
What Is ZRX (0x)?
ZRX is the governance and utility token of the 0x protocol, an open-source, Ethereum-based framework that facilitates the decentralized exchange of ERC-20 and other Ethereum-compatible tokens. Launched in 2017, the 0x protocol was designed to solve one of DeFi’s earliest challenges: fragmented liquidity and inefficient on-chain trading.
Instead of requiring every trade to be executed directly on the blockchain (which can be slow and expensive), 0x introduces a hybrid model that combines off-chain order relay with on-chain settlement. This approach significantly reduces transaction costs and increases trading speed while maintaining decentralization and security.

How the 0x Protocol Works
At its core, the 0x protocol enables two primary modes of trading:
- Peer-to-Peer (P2P) Orders
These are private orders created between two parties. The buyer and seller negotiate terms off-chain, and once agreed upon, the transaction is settled on the Ethereum blockchain via a smart contract. This method enhances privacy and prevents front-running or manipulation by third parties. - Broadcasted Orders (Public Market Making)
Orders are publicly shared across relayers—entities or platforms that host order books. Anyone can view and fill these orders. While the order creation and discovery happen off-chain, execution always occurs on-chain through 0x smart contracts, eliminating the need for trusted intermediaries.
This hybrid architecture—off-chain order books with on-chain settlement—is what makes 0x both efficient and secure. It allows developers to build decentralized applications (DApps) with integrated trading functionality without reinventing the wheel.
The Role of ZRX in the Ecosystem
ZRX isn’t just a speculative asset; it plays several critical roles within the 0x ecosystem:
- Governance: ZRX holders can participate in protocol upgrades, parameter changes, and funding proposals through decentralized governance. This ensures the network evolves according to community consensus.
- Staking Incentives: Market makers and relayers can stake ZRX to signal reliability and gain access to fee discounts or rewards.
- Protocol Fees (Historically): While early versions of 0x charged fees in ZRX for certain operations, later iterations shifted toward more flexible monetization models for relayers.
With a total supply capped at 1 billion tokens and approximately 848.39 million currently in circulation, ZRX maintains scarcity while supporting widespread distribution across the DeFi community.

Despite fluctuations in price, ZRX remains a significant player in the DeFi infrastructure space, ranking among the top 300 cryptocurrencies by market capitalization.
Its longevity and continued integration into various DApps underscore its relevance in a competitive landscape dominated by newer protocols.
Why Developers Choose 0x
For blockchain developers building DeFi platforms, integrating native trading features from scratch is complex and resource-intensive. The 0x protocol offers a battle-tested solution with key advantages:
- Modular Design: Developers can use specific components (e.g., order matching, settlement) without adopting the entire system.
- Open Source & Permissionless: Anyone can access and contribute to the codebase, fostering innovation and transparency.
- Cross-Chain Expansion: Beyond Ethereum, 0x has expanded support to Layer 2 networks like Polygon, Arbitrum, and zkSync, improving scalability and reducing gas fees.
- Liquidity Aggregation: By connecting to multiple relayers and DEX aggregators, apps using 0x gain access to deeper liquidity pools.
These features make 0x a preferred choice for wallets, NFT marketplaces, and DeFi aggregators looking to embed seamless token swaps.

Frequently Asked Questions (FAQ)
What is ZRX used for?
ZRX is primarily used for governance within the 0x decentralized autonomous organization (DAO). Token holders vote on proposals related to protocol development, upgrades, and treasury management. It also supports staking mechanisms that incentivize reliable relayers and market makers.
Is 0x a decentralized exchange?
Not exactly. The 0x protocol is not a standalone exchange like Uniswap or SushiSwap. Instead, it's a foundational layer that enables others to build decentralized exchanges or integrate trading into their apps. Think of it as the “backend” infrastructure powering many DEXs.
Can I stake ZRX tokens?
Yes, users can stake ZRX through designated staking pools or relayer systems to support network operations. In return, they may earn rewards or fee rebates, depending on the implementation.
How does 0x reduce transaction costs?
By moving order creation and matching off-chain, 0x avoids congestion and high gas fees associated with constant on-chain activity. Only final settlements are recorded on Ethereum, making trades faster and cheaper.
Is ZRX a good investment?
As with any cryptocurrency, investing in ZRX carries risks. Its value depends on adoption of the 0x protocol, growth in DeFi usage, and broader market conditions. Always conduct thorough research before investing.
Where can I buy ZRX?
ZRX is available on major cryptocurrency exchanges including OKX, Coinbase, Binance, and Kraken. You can trade it against stablecoins like USDT or major cryptos like ETH.
The Future of 0x and ZRX
Looking ahead, the 0x team continues to focus on scalability, cross-chain interoperability, and enhancing developer tooling. With increasing demand for embedded finance solutions—such as in-game asset swaps or wallet-integrated trading—the relevance of modular protocols like 0x is only expected to grow.
Moreover, as Ethereum evolves with Layer 2 scaling solutions, 0x is well-positioned to serve as a universal liquidity layer across chains, further solidifying ZRX’s role in the DeFi stack.
