CEX vs DEX: What Is the Difference?

Crypto trades happen on two very different kinds of venue: centralized exchanges (CEXs) and decentralized exchanges (DEXs). Knowing the difference helps you weigh convenience against control and risk.

Centralized exchanges

A CEX is a company that holds your funds and matches trades, much like a broker. They are easy to use and liquid, but you are trusting the company with custody — “not your keys, not your coins” is the well-worn warning.

Decentralized exchanges

A DEX lets you trade directly from your own wallet against smart contracts, keeping custody yourself. That removes company risk but adds smart-contract risk, complexity, and no support desk.
