Quick Fact
Since its launch in 2017, 0x Labs has raised over $109 million, powering more than $125 billion in volume across 6 million transactions and enabling over 150 integrations (including Matcha, dYdX, MetaMask, and Coinbase Wallet).
0x is an open-source protocol developed by 0x Labs that provides secure, efficient, and fully decentralized infrastructure for tokenized asset exchange across multiple blockchain networks. Launched in 2017, 0x is best known for powering a range of decentralized exchanges, DEX aggregators, NFT marketplaces, and Web3 wallets through its modular smart contracts and robust developer tools.
With a mission to create a more equitable financial system, 0x enables frictionless peer-to-peer token trading while maintaining full user custody.
Core Offerings
1. Swap API and Aggregation
0x aggregates liquidity across more than 100 decentralized exchanges, offering highly efficient pricing through its Swap API. This backend powers some of the most widely used DeFi products—including Matcha, MetaMask, and dYdX—ensuring users receive optimal prices with minimal slippage.
2. Gasless API for Meta-Transactions
Developers can integrate 0x’s Gasless API to enable fee-less token swaps for end-users. This feature abstracts away the complexity of transaction costs, improving onboarding and usability in wallets, games, and consumer-facing dApps.
3. NFT and Multi-Asset Support
With the introduction of 0x Protocol v4, the platform supports ERC-721 and ERC-1155 token standards, enabling NFT swaps and batch transactions with reduced gas usage—up to 54% more efficient than prior versions.
4. Developer-First Tooling
0x provides extensive tooling, SDKs, and open APIs, enabling developers to quickly launch DEXs, aggregators, marketplaces, or embedded swap functionalities in applications—without requiring deep smart contract expertise. Why 0x Matters
0x is more than just a DEX protocol — it's a critical layer of Web3 infrastructure that enables decentralized finance and commerce to function at scale. With its open architecture and emphasis on interoperability, 0x empowers developers to build user-friendly, gas-efficient, and cross-chain trading applications.
As Web3 continues to evolve into a multichain and multi-asset ecosystem, 0x plays a foundational role by unifying fragmented liquidity and abstracting away blockchain complexity.
