The world of decentralized finance (DeFi) continues to reshape how we think about financial transactions, ownership, and value exchange. Among the many projects driving innovation in this space, 0x (ZRX) stands out as a foundational protocol enabling seamless peer-to-peer trading of digital assets. But what exactly is ZRX coin, and where can you buy it? This comprehensive guide dives into the core mechanics of the 0x protocol, the utility and potential of ZRX, and how you can get involved in one of DeFi’s most influential ecosystems.
Understanding Decentralized Finance (DeFi)
Decentralized finance, or DeFi, refers to a new financial system built on public blockchains—primarily Ethereum—that removes intermediaries like banks and brokers. Instead, DeFi uses smart contracts to automate services such as lending, borrowing, trading, and staking. These trustless systems allow users to retain full control over their assets while accessing global markets 24/7.
One of the key advantages of DeFi is its open access. Anyone with an internet connection and a crypto wallet can participate—no credit checks, no gatekeeping. This inclusivity has fueled rapid growth, with billions of dollars now locked in DeFi protocols.

What is the 0x Protocol?
At the heart of ZRX lies the 0x protocol, an open-source framework designed to facilitate the decentralized exchange of ERC20 tokens and other Ethereum-based assets. Launched in 2017 by founders Will Warren and Amir Bandeali, 0x enables developers to build decentralized applications (dApps) that support instant token swaps across multiple platforms.
Rather than acting as a single exchange, 0x functions as a liquidity infrastructure layer—a backend system that powers other DeFi apps. It aggregates order books and liquidity from various sources, both on-chain and off-chain, allowing users to find the best possible prices across decentralized exchanges (DEXs) like Uniswap, Balancer, and Curve.
The protocol achieves efficiency through off-chain order relay and on-chain settlement. Orders are broadcast off-chain to reduce gas costs, then settled securely on Ethereum. This hybrid model improves speed and lowers transaction fees.
Key Participants in the 0x Network
- Market Makers: Users who create buy/sell orders.
- Takers: Those who accept and fulfill existing orders.
- Relayers: Entities that host order books and facilitate order discovery (though they don’t execute trades).
What is ZRX Cryptocurrency?
ZRX is an ERC20 governance and staking token that powers the 0x ecosystem. While not required for transaction fees (which are paid in ETH), ZRX plays a crucial role in protocol governance and incentivizing liquidity providers.
Core Functions of ZRX
- Governance: Holders vote on upgrades, fee structures, and treasury allocations.
- Staking: Users can stake ZRX or delegate it to market makers to earn rewards.
- Protocol Incentives: Stakers help secure the network and improve liquidity efficiency.
Since its launch during a successful $24 million ICO in August 2017—backed by major investors like Pantera Capital and Blockchain Capital—ZRX has evolved into a key player in DeFi infrastructure.
ZRX Price and Market Performance
As of late 2025, ZRX maintains a strong market presence:
- Circulating Supply: ~845 million ZRX (85% of max supply)
- Max Supply: 1 billion tokens
- Market Cap: Over $940 million
- All-Time High: $2.53 (reached in 2022)
- All-Time Low: $0.104 (August 2017)
ZRX is not mineable—it operates under a pre-minted model. Its price has shown significant volatility, with notable surges such as a rise from $0.74 to $1.92 within a month in early 2025, reflecting growing interest in DeFi infrastructure tokens.
With a 24-hour trading volume regularly exceeding $95 million, ZRX remains highly liquid and widely available across major exchanges.
Advantages of the 0x Ecosystem
1. Liquidity Aggregation via 0x API
The 0x API is one of the most advanced liquidity aggregators in DeFi. It scans dozens of DEXs in real time, splitting large orders across platforms to minimize slippage and maximize returns. Studies suggest it delivers better net prices than competitors like Uniswap or Paraswap in over 70% of cases.
2. Matcha: The Smart Trading Interface
0x Matcha is a user-friendly trading interface that leverages the 0x API to offer best-rate swaps across 26+ DEXs. Key benefits include:
- No account creation required
- Direct wallet-to-wallet trading
- Transparent pricing with no hidden fees
- Support for limit orders and advanced trade types

3. Developer Empowerment
By providing modular, composable tools, 0x empowers developers to integrate decentralized trading into dApps without rebuilding complex infrastructure from scratch.
Potential Concerns with 0x (ZRX)
Despite its strengths, 0x faces challenges:
- Token Utility Debate: Critics argue that using ZRX to pay relayer fees is redundant since ETH is already used for gas.
- Security Review Findings: A study by Cornell Tech noted ambiguities in the whitepaper regarding ZRX's governance role and incomplete code specifications.
- Direct Peer-to-Peer Bypass Risk: Since order books are public, makers and takers could theoretically trade directly, undermining relayers.
These issues highlight ongoing debates in DeFi about token design and economic sustainability.
Where to Buy ZRX Tokens?
ZRX is listed on over 200 cryptocurrency exchanges, making it highly accessible. You can purchase ZRX using:
- Fiat currencies (USD, EUR, GBP)
- Major cryptocurrencies (BTC, ETH, USDT)
Popular platforms include Binance, Coinbase, Kraken, and Gemini. Additionally, decentralized options like Matcha allow direct wallet-based purchases without KYC.

Where to Store ZRX?
Since ZRX is an ERC20 token, it can be stored in any Ethereum-compatible wallet:
- Hardware Wallets: Ledger, Trezor
- Software Wallets: MetaMask, Trust Wallet
- Mobile & Desktop Wallets: Including multi-chain solutions
Always ensure your wallet supports ERC20 tokens before transferring funds.
Is ZRX a Good Investment?
Like all cryptocurrencies, ZRX carries high volatility and risk. However, several factors support its long-term potential:
- Foundational role in DeFi infrastructure
- Strong developer adoption
- Ongoing improvements in staking and governance
That said, market sentiment fluctuates rapidly. While early investors have seen substantial gains—over 886% ROI since launch—future performance depends on broader DeFi growth and protocol adoption.
Always conduct thorough research (DYOR) and never invest more than you can afford to lose.
