CEX vs DEX

Understand the difference between centralized and decentralized exchanges.

Step 1

Core difference

CEX and DEX both let you trade, but custody and responsibility are not the same.

  • CEX: platform holds keys, account-based experience.
  • DEX: you hold keys, wallet-based experience.
  • Both can coexist in one user journey.

The key distinction is custody of keys.

Key takeaway

The key question is: who controls the keys?

Step 2

When to use each

Beginners usually start with CEX for onboarding, then use DEX as they gain confidence.

  • CEX: fiat on-ramp, support, easier first buy.
  • DEX: self-custody, token access, on-chain transparency.
  • Security habits are required in both cases.

Key takeaway

Use CEX for convenience, DEX for autonomy.

Step 3

Minimal risk checklist

Before each action, run a short checklist to avoid common mistakes.

  • Verify URL and domain spelling.
  • Check network and fees before confirming.
  • Never share seed phrase or private key.

Key takeaway

One minute of verification prevents most beginner losses.
