What is 0x Protocol (ZRX)?

Deep Dive

1. Purpose & Value Proposition

0x solves fragmented liquidity in decentralized trading by providing a standardized protocol for developers to build efficient exchange features. It supports ERC-20 tokens and assets on Ethereum, Solana, Monad, and other chains, enabling seamless cross-chain swaps. Over $200B in cumulative trading volume has been processed through its infrastructure since 2016 (0x docs).

2. Technology & Architecture

The protocol uses a hybrid model: order matching occurs off-chain (reducing congestion), while settlements execute on-chain via audited smart contracts. Its Swap API aggregates liquidity from AMMs (like Uniswap) and order books (e.g., KuruExchange), splitting trades for optimal pricing. Recent upgrades focus on gas efficiency and multi-chain interoperability, such as integrating with Coin98 Wallet (1.2M users) and Monad’s high-throughput blockchain.

3. Tokenomics & Governance

ZRX, an ERC-20 token, powers governance and staking. Holders vote on protocol changes and allocate funds from the community treasury. Stakers earn rewards by providing liquidity to market makers. With a fixed supply of 1B tokens (848M circulating), ZRX’s utility is tied to ecosystem growth rather than transaction fees.

Conclusion

0x Protocol is a foundational layer for decentralized trading, prioritizing developer flexibility and cross-chain interoperability. As DeFi expands, how will 0x balance its role as a neutral infrastructure provider against competing DEX aggregators?
