CEX versus DEX

Architecture

Centralized exchanges (CEXs) represent a traditional financial infrastructure, functioning as intermediaries that maintain custody of user funds and facilitate order matching through a centralized order book; this structure necessitates trust in the exchange’s security and operational integrity, impacting counterparty risk assessment. Decentralized exchanges (DEXs), conversely, leverage smart contracts to enable peer-to-peer trading directly on a blockchain, eliminating the need for a central authority and reducing systemic risk associated with single points of failure. The architectural divergence fundamentally alters market access, transparency, and the potential for censorship resistance, influencing the overall ecosystem dynamics. This distinction impacts the implementation of sophisticated trading strategies, particularly those reliant on high-frequency execution or complex order types.
