What 0x does
0x is a decentralized exchange infrastructure provider founded in 2017 by Will Warren and Amir Bandeali, headquartered in San Francisco with a globally-remote team of 101-250 employees. The company provides APIs that enable developers to embed onchain token trading, cross-chain swaps, and gasless transactions into applications without building DEX integration infrastructure from scratch. Its core technology stack includes the Swap API (aggregating liquidity from 370+ DEX sources across 25+ blockchains), the Cross-Chain API (aggregating 12+ bridge providers for cross-chain value transfer with 99.97% uptime and 10-second median bridge time), the Gasless API (meta-transaction support to abstract gas costs from end users), and the Trade Analytics API (trading insights and usage metrics). The underlying 0x Protocol is open-source smart contract infrastructure that has processed over 211 million transactions and $180 billion in trading volume since inception.
The company's customer base spans enterprise wallet providers (Coinbase, MetaMask, Robinhood Wallet, Phantom, Trust Wallet, Bitget Wallet), exchanges and DeFi protocols (DeFi Saver, Phuture, OpenSea), SocialFi platforms (Zora, Base App, Bankr, Moxie, Interface), and Layer 2 networks (Abstract). Matcha, 0x's consumer-facing DEX aggregator, serves retail traders and delivers best price on 93% of trades while showcasing the underlying API capabilities. Notable integrations with AI agent payment standards (Coinbase's x402, Google's AP2, OpenAI's Agentic Commerce Protocol) position 0x as execution infrastructure for autonomous agent commerce.
Revenue is generated through a combination of API subscription tiers (free and paid enterprise plans with usage-based limits), the 0x Swap Fee charged on certain transactions routed through the API, integrator-set percentage fees, and positive slippage capture. Pricing is partially disclosed with custom enterprise plans available for high-volume applications. The company has raised $109 million total through a $70 million Series B led by Greylock Partners in April 2022, with participation from Pantera Capital, Jump Capital, Coinbase, and OpenSea, and acquired rival DEX aggregator Flood in May 2025 to strengthen its position in the $2.3 billion DEX aggregation market.

Revenue model
- API Subscription and Usage Fees: 0x offers tiered subscription plans for API access with different rate limits and feature sets. Enterprise customers pay based on API call volumes and may receive custom plans. The company generates revenue through fees charged to licensees for API usage, as documented in the API License Agreement which references service terms and pricing tiers.
- 0x Swap Fee (Transaction Fees): 0x charges a transaction fee (0x Swap Fee) on certain trades executed through the API. The fee is disclosed to users prior to transactions. Integrators can also set percentage fees and capture positive slippage from swaps within their applications.
- Matcha Consumer Trading: Matcha, the company's consumer-facing DEX aggregator, captures trading volume from retail users. Revenue is generated through the same transaction fee mechanism as the API business.

0x competitors and assessment
Company assessmentDirect peers
- 1inch Network: 1inch is the largest DEX aggregator by volume, offering smart order routing across multiple chains and liquidity sources. It competes directly with 0x's Swap API for wallet, exchange, and DeFi protocol integrations.
- Jupiter: Jupiter is the leading DEX aggregator on Solana, with expanding cross-chain routing. It is the closest analogue to 0x's Swap API on a non-EVM chain and a primary target for 0x's Solana API launch.
- CoW Swap (CoW Protocol): CoW Swap uses batch auctions and MEV-protected intents for DEX aggregation. It targets the same wallet and trader integrations as 0x, with a differentiated execution mechanism.
- ParaSwap: ParaSwap is a multi-chain DEX aggregator providing smart order routing for wallets and DeFi applications. It is a direct functional competitor to 0x's Swap API for EVM integrations.
- KyberSwap (Kyber Network): KyberSwap combines an AMM-based DEX with aggregation across chains and liquidity sources. It competes with 0x for wallet and DApp swap integrations across EVM chains.
- OpenOcean: OpenOcean is a cross-chain DEX aggregator offering aggregated routing across EVM and non-EVM chains. It overlaps with both 0x's Swap API and Cross-Chain API offerings.
- LI.FI: LI.FI aggregates bridges and DEX liquidity into a single cross-chain swap API. It is the most direct competitor to 0x's Cross-Chain API for wallet and payment use cases.
- Socket (SocketHQ): Socket provides a modular cross-chain interoperability stack aggregating bridges and DEXes. It competes with 0x's Cross-Chain API for cross-chain execution and bridging use cases.
- Rango Exchange: Rango is a cross-chain DEX and bridge aggregator targeting wallets and DApps. It directly competes with 0x's combined Swap and Cross-Chain APIs for multi-chain swap integrations.
Broad incumbents
- Uniswap: Uniswap is the dominant AMM protocol and a primary liquidity source that 0x aggregates. It is also an indirect competitor as Uniswap's own Universal Router increasingly offers aggregation-native execution to wallets.
