The evolution of decentralized finance (DeFi) has brought forward innovative solutions to streamline how digital assets are traded across blockchain networks. At the forefront of this transformation is 0x, a foundational decentralized exchange infrastructure designed to enable seamless, secure, and efficient token swaps across multiple chains. With its modular architecture and open-source protocols, 0x empowers developers, platforms, and traders to access aggregated liquidity and execute trades with minimal friction.
Whether you're building a DeFi application or simply navigating the world of crypto trading, understanding 0x’s role in the ecosystem is essential. This article explores the core components, technology, market performance, and real-world applications of 0x — all while integrating key SEO-friendly terms such as decentralized exchange infrastructure, Web3 trading, 0x protocol, ZRX token, DeFi liquidity, NFT trading, and multi-chain aggregation.
What Is 0x?
0x is a decentralized exchange (DEX) infrastructure protocol that enables peer-to-peer asset trading on Ethereum and other compatible blockchains. Unlike traditional exchanges, 0x does not operate a centralized order book or custody user funds. Instead, it provides the underlying tools and smart contracts that allow developers to build their own trading interfaces or integrate decentralized trading directly into dApps.
At its core, 0x aims to create a world where all forms of value — from cryptocurrencies and DeFi tokens to NFTs — can move freely across platforms without intermediaries. Its vision centers around a tokenized economy where assets are interoperable, accessible, and efficiently priced through decentralized mechanisms.

Core Components of the 0x Ecosystem
1. 0x Protocol
The backbone of the ecosystem, the 0x Protocol is an open-source set of smart contracts that facilitates off-chain order relay with on-chain settlement. This hybrid model reduces gas costs and increases transaction speed while maintaining security and decentralization.
Developers can use the protocol to create custom trading experiences, embed swap functionality into wallets or marketplaces, or aggregate liquidity from various sources. Orders are signed off-chain and only settled when executed, minimizing blockchain congestion.
2. 0x API
One of the most powerful tools offered by 0x is its multi-chain aggregation API. This service automatically scans dozens of decentralized exchanges — including Uniswap, SushiSwap, Curve, and Balancer — across Ethereum, Polygon, Arbitrum, Optimism, and more to find the best possible price for any given trade.
By routing trades through the most cost-effective paths and splitting orders across multiple venues when beneficial, the 0x API ensures optimal execution for both retail users and institutional integrators.
3. Matcha by 0x
Matcha is 0x’s user-facing trading platform — a sleek, non-custodial token swap interface that leverages the full power of the 0x API. Designed for ease of use without sacrificing control, Matcha allows users to trade ERC-20 tokens and NFTs across multiple chains while benefiting from deep liquidity and competitive pricing.
With features like slippage protection, wallet connectivity, and real-time price comparisons, Matcha exemplifies how decentralized infrastructure can deliver centralized-exchange-level convenience.
ZRX Token: Utility and Economics
The native cryptocurrency of the 0x ecosystem is ZRX, an ERC-20 token launched in August 2017 during one of the earliest major ICOs in the DeFi space. With a total supply capped at 1 billion tokens, ZRX serves two primary functions:
- Governance: Holders can vote on proposals related to protocol upgrades, fee structures, treasury management, and future development directions.
- Staking Incentives: Although not used for transaction validation in the traditional sense, ZRX has historically been involved in staking programs that reward relayers and market makers who contribute liquidity.
As of now:
- Current Price: $0.2197
- 24-Hour Trading Volume: $18.8 million
- Market Cap: $186.4 million (ranked #214)
- All-Time High: $2.50 (January 13, 2018)
- All-Time Low: $0.1206 (March 13, 2020)
Despite market fluctuations, ZRX remains integral to the governance and long-term sustainability of the protocol.
Funding and Growth Milestones
0x has secured significant backing from top-tier investors in the blockchain space:
- February 2021: Raised $15 million in Series A funding.
- April 2022: Closed a $70 million Series B round, bringing total raised capital to **$85 million**.
These funds have been directed toward expanding developer tools, enhancing cross-chain capabilities, and growing the Matcha platform’s user base.
Why Developers Choose 0x
For builders in Web3, integrating native trading functionality can be technically complex and resource-intensive. 0x simplifies this process by offering:
- Plug-and-play SDKs and APIs
- Support for over 15+ blockchain networks

Use Cases Across Web3
DeFi Platforms
Lending protocols, yield aggregators, and multi-chain bridges use 0x API to let users convert assets instantly before depositing or withdrawing.
NFT Marketplaces
Buyers can swap ETH for WETH or stablecoins directly within NFT platforms powered by 0x — improving conversion rates and reducing drop-offs.
Wallet Integrations
Crypto wallets embed Matcha or the 0x API to offer built-in swap functionality without redirecting users to external DEXs.
Frequently Asked Questions (FAQ)
Q: Is 0x a centralized or decentralized exchange?
A: 0x itself is not an exchange but a decentralized exchange infrastructure. It provides the tools others use to build DEXs or add trading features. The protocol operates without central control.
Q: Can I stake ZRX tokens?
A: While ZRX is primarily used for governance, past initiatives included staking programs for relayers. Future staking opportunities may return depending on community governance decisions.
Q: Does 0x support NFT trading?
A: Yes. Matcha by 0x supports NFT swaps on certain chains, allowing users to trade non-fungible tokens using integrated DeFi liquidity sources.
Q: How does the 0x API find the best prices?
A: The API aggregates liquidity from major DEXs across multiple chains and uses sophisticated routing algorithms to minimize slippage and maximize output.
Q: On which blockchains does 0x operate?
A: The protocol supports Ethereum, Polygon, Arbitrum, Optimism, Avalanche, BNB Chain, Fantom, Gnosis Chain, and several others — making it one of the most widely integrated multi-chain solutions.
