0x (ZRX) is a decentralized protocol enabling peer-to-peer (P2P) exchange of Ethereum-based assets. Developed by 0x Labs, it acts as an open standard and foundational DeFi component, offering developers tools to embed trading functionalities into applications. The protocol features:
- Audited Smart Contracts: Secure, on-chain trade execution.
- 0x Mesh: A decentralized global P2P order book for enhanced liquidity.
- Liquidity API: Aggregates liquidity from multiple exchanges.

Key Features of 0x Protocol
Decentralized Exchanges (DEXs)
0x facilitates non-custodial trading via smart contracts, eliminating intermediaries. Trades occur directly between users, ensuring security and transparency.
Hybrid Architecture
- Off-chain Order Relay: Reduces Ethereum gas fees.
- On-chain Settlement: Ensures tamper-proof transactions.
Governance via ZRX Token
Holders vote on 0x Improvement Proposals (ZEIPs), influencing protocol upgrades like fee structures or new features.
Staking Rewards
ZRX stakers earn ETH rewards proportional to trading volume, incentivizing liquidity provision.
Ecosystem Components
0x Mesh
A P2P order book independent of Ethereum, boosting liquidity and accessibility.
Matcha
A DEX aggregator by 0x Labs that sources optimal prices across platforms for seamless trading.
Relayers
Non-custodial services (e.g., MetaMask) assist in order creation and matching without holding user funds.
Use Cases
- Niche DEXs: Custom exchanges for specific assets (e.g., NFTs, gaming tokens).
- DeFi Liquidity: Integration with lending/borrowing protocols.
- OTC Desks: Private, large-volume trades.
- Trading Bots: Arbitrage and market-making strategies.

ZRX Token Utility
- Governance: Vote on protocol upgrades.
- Staking: Earn ETH rewards by staking ZRX in liquidity pools.
Vision for a Tokenized Future
0x aims to unlock frictionless trading of all value types—stocks, real estate, commodities—on public blockchains. Its multi-chain expansion (beyond Ethereum) positions it as a DeFi cornerstone.
FAQs
1. What is the 0x protocol?
A P2P trading system for digital assets using off-chain orders and on-chain settlements via Ethereum smart contracts. Key tools include 0x Mesh and liquidity APIs, with ZRX enabling governance and staking.
2. What is the 0x limit order protocol?
A method for setting fixed-price trades off-chain, settled on-chain. "Makers" create orders, matched by "takers," reducing costs while ensuring secure asset swaps.
3. How does 0x differ from centralized exchanges?
0x eliminates custodial risks by enabling direct P2P trades via decentralized infrastructure, with relayers facilitating order matching without holding assets.
4. Can ZRX tokens be staked?
Yes. Staking ZRX in liquidity pools earns ETH rewards based on trading volume and pool contribution.
5. What blockchains support 0x?
Initially Ethereum-focused, 0x now extends to other chains for cross-chain liquidity.
6. Is 0x open-source?
Absolutely. The protocol’s smart contracts and tools are publicly auditable and modifiable via community governance.
