Decentralized finance (DeFi) revolutionized asset trading by eliminating intermediaries. Among the pioneers stands 0x—a protocol enabling seamless exchange of Ethereum-based tokens.
Understanding 0x Protocol
The 0x protocol facilitates trustless trading of digital assets via hybrid on-chain/off-chain infrastructure. Unlike traditional decentralized exchanges (DEXs) like Uniswap or dYdX, which rely entirely on blockchain transactions, 0x optimizes efficiency:
- Off-chain order relay: Makers post orders without immediate blockchain fees.
- On-chain settlement: Takers finalize trades only when matched, reducing gas costs.
Built for EVM-compatible chains (Ethereum, Polygon, Avalanche), 0x supports:
- ERC-20 tokens
- NFTs

History and Development
Founders and Milestones
- 2016: Will Warren (ex-Brave engineer) and Amir Bandeali (trading specialist) founded 0x Labs.
- 2017: Whitepaper release; ICO raised $24 million (500M ZRX sold).
- 2022: Secured $70M in VC funding led by Greylock.
- 2023: V4 upgrade introduced DEX aggregation to enhance liquidity.
How 0x Works
Key Components
| Role | Function |
|------|----------|
| Makers | Provide liquidity via limit orders |
| Takers | Execute trades using pooled liquidity |
Trade Flow
- Order Creation: Maker submits off-chain order.
- Matching: Taker finds compatible order via 0x’s aggregator.
- Settlement: Transaction finalized on-chain.
Advantage: Lower fees and minimized slippage vs. full on-chain DEXs.
0x Ecosystem Products
- Swap API: Integrates 0x liquidity into dApps.
- Matcha: User-friendly DEX aggregator.
- NFT Swap SDK: Multi-chain NFT trading toolkit.
ZRX Token Utility
- Governance: Holders vote on protocol upgrades.
- Rewards: Incentivizes relayers and liquidity providers.
Tokenomics
- Total supply: 1B ZRX (50% sold in ICO).
- Allocations: 15% dev fund, 10% team (vested until 2021).
FAQ
Q: Is 0x a DEX?
A: No—it’s a protocol enabling DEXs to build atop its infrastructure.
Q: Which chains support 0x?
A: Ethereum, Polygon, Optimism, and other EVM-compatible networks.
Q: How does 0x differ from Uniswap?
A: 0x uses order books + off-chain matching; Uniswap relies on automated market makers (AMMs).
Key Takeaways
- 0x enables gas-efficient trading via hybrid settlement.
- ZRX powers decentralized governance and participant rewards.
- Used by top DeFi projects like Matcha and dYdX.
For developers and traders alike, 0x represents a cornerstone of Ethereum’s DeFi landscape.
