Adecentralized crypto exchange (DEX) allows users to trade digital assets without relying on a central authority. Trades are executed via smart contracts on blockchain networks, ensuring greater transparency, security, and user control. DEXs reduce hacking risks and offer anonymity, attracting users seeking privacy and decentralization. Liquidity pools, automated market makers (AMMs), and wallet integration are common components. These exchanges enable global, permissionless trading and are vital to the DeFi ecosystem, as they eliminate the need for third parties while enhancing financial inclusivity and system resilience.
