DEX vs CEX: Decentralized vs Centralized Exchanges
Bottom line: company-run vs code-run
There are two kinds of crypto exchange. A CEX (centralized exchange) is run by a company. A DEX (decentralized exchange) runs on smart contracts, letting wallets trade directly.
Key takeaways
CEX = company-managed (easy, support, KYC). DEX = no middleman (free but self-custody and self-responsibility). Beginners usually start with a CEX.
Side by side
| Aspect | CEX | DEX |
|---|---|---|
| Operator | A company | Smart contracts |
| Who holds assets | The exchange | Your own wallet |
| KYC | Usually required | Often not |
| Support | Yes | Self-responsibility |
On a DEX, anyone can list a token
That includes worthless or malicious tokens. Be careful approving unknown tokens.
