What Is a Centralized Crypto Exchange (CEX)?
Centralized exchanges (CEXs) function similarly to traditional stock markets, with a governing entity overseeing operations. These platforms act as intermediaries, facilitating trades, safeguarding assets, and enforcing security measures. Examples include Binance and OKX.

Key Traits of CEXs:
- Custodial control: Funds are held by the exchange.
- Regulated environment: Compliance with KYC/AML laws.
- High liquidity: Deep order books for seamless trading.
What Is a Decentralized Exchange (DEX)?
Decentralized exchanges (DEXs) eliminate intermediaries, enabling peer-to-peer trading via smart contracts on blockchains like Ethereum. Users retain full custody of their assets, aligning with crypto’s ethos of self-sovereignty.
Key Traits of DEXs:
- Non-custodial: Trades occur directly from users’ wallets.
- Permissionless: No KYC requirements.
- Transparent: Transactions are recorded on-chain.
