What is 0x Protocol (ZRX)?
Developed by 0x Labs, 0x Protocol is an open-source protocol that allows building DEX and DApp integrating cryptocurrency asset trading. It provides the ability to directly exchange tokens on-chain with low gas fees, while optimizing liquidity from multiple sources through advanced APIs.
This protocol plays a central role for a range of wallets and Web3 applications, with outstanding multi-chain compatibility, expanding the potential for global DeFi development.
How does 0x Protocol work?
0x operates on the "off-chain order relay, on-chain settlement" model to save transaction costs and increase order matching speed. Makers create off-chain trading orders, relayers manage the order book until Takers submit orders to the blockchain to execute token swaps.
This allows for significant gas fee reductions compared to traditional DEXs. This mechanism has been successfully implemented by 0x Labs and has received high praise from the community and DeFi experts.
"The off-chain relay model combined with on-chain settlement opens a sustainable development path for DEXs with superior user experiences."
Will Warren – Co-founder & CEO 0x Labs, 2025
