Decentralized exchanges (DEXs) are evolving beyond basic smart contract functionality to tackle the complex challenges of liquidity, latency, and Maximal Extractable Value (MEV) protection. As DEXs gain market share from centralized exchanges, they must ensure deep liquidity, minimize latency, and protect users from MEV attacks to maintain user trust and satisfaction. To achieve this, DEXs are focusing on robust system architecture that includes automatic order splitting across pools, liquidity aggregators, and comprehensive security measures. These measures include monitoring liquidity anomalies, implementing automatic risk controls, and providing clear user guidance on transaction processes. By prioritizing infrastructure and user experience, DEXs aim to offer the speed, clarity, and convenience users expect from centralized platforms, ensuring their long-term viability in the decentralized finance ecosystem.
