Exchange vs Decentralized Exchange (DEX): The Difference Is Who Holds Your Money
Guides · · Satoshi Note Editorial
Read in: 한국어
Satoshi Note lists names like Upbit and Binance next to names like Hyperliquid and dYdX. They sound alike but work differently.
At a glance
- A centralized exchange (CEX) is a company that holds your account and assets. A decentralized exchange (DEX) lets you connect your own wallet, and a program (a blockchain) enforces the rules.
- DEX activity is often public, which is one reason Satoshi Note can collect public traders' positions.
- This is not a "which is better" piece. It describes two different structures.
The biggest difference: who holds the assets
Centralized exchange (CEX): places like Upbit, Bithumb and Binance. You sign up, deposit, and your assets are recorded in your account and managed by the exchange. Forget your password and support can help. In exchange, you are exposed if the exchange itself runs into trouble.
Decentralized exchange (DEX): places like Hyperliquid, dYdX, Pacifica and Lighter. You do not open an account; you connect your crypto wallet. Assets sit in your wallet or in a trading program (a smart contract), and you hold the key (private key). Lose the key and there is no one to call.

Why Satoshi Note shows many DEX traders
On many DEXs, positions and trades per wallet address are public, so you can see which side someone holds and how much. A personal position on a CEX is not visible outside the exchange. Satoshi Note's trader pages therefore center on wallets where public data exists. That is only the public wallets, not the whole market, and some wallets do not reveal a liquidation price (related post).
Where "My Assets" fits
My Assets collects balances and trades from your own accounts connected through exchange APIs. A read-only key cannot withdraw (read-only key guide). The trader pages and My Assets use different data.

FAQ
Is a DEX safer?
They are different structures, and neither is simply safer. Exchange operation risk weighs more on a CEX; key management and program bugs weigh more on a DEX.
Does a DEX address reveal who someone is?
An address is a string of characters with no name attached. Satoshi Note's rule is to show only the first six characters of an address.
Can I use a DEX where I live?
