What is 0x?
0x Protocol is an open-source, decentralized protocol that facilitates the peer-to-peer exchange of assets on Ethereum, Base, Arbitrum, Optimism, Polygon, BNB Chain, Avalanche, Scroll, Linea and Blast. 0x offers a flexible framework for building dApps, particularly decentralized exchanges, on Ethereum and other blockchains. The protocol allows developers to create markets for any kind of tokenized asset, promoting greater liquidity, transparency and security in asset trading.
How does 0x Protocol work?
0x operates as an off-chain order relay with an on-chain settlement system. This means it leverages both off-chain and on-chain processes to increase efficiency and reduce transaction costs.

FAQ
What is liquidity aggregation?
Liquidity aggregation combines liquidity from multiple sources to give users access to the best rates and minimal slippage during token swaps – all within a single place. By tapping into liquidity across the entire market, 1inch simplifies the swapping process, saving users time and effort. This efficient, decentralized approach enhances the swapping experience in a self-custodial environment.
Why is DEX aggregation important?
DEX aggregation is crucial because it enables users to access competitive prices and optimal liquidity across multiple decentralized exchanges through a single interface. Since different DEXes may offer varying prices for the same asset, DEX aggregation eliminates the need for manual comparison, ensuring users get the best possible rates. Additionally, swaps can be split across different protocols and market depths, optimizing both swap prices and gas usage. With 1inch, users enjoy a seamless experience that consistently delivers top-tier rates and efficiency.
