What Are CEX and DEX?
Centralized Exchanges (CEX)
CEX refers to centralized cryptocurrency exchanges—platforms managed by a central authority where users deposit funds into institutional wallets. Functioning similarly to traditional stock exchanges, CEXs rely on third-party intermediaries to facilitate trades and custody assets.
Key Advantages:
- Beginner-friendly interfaces
- Faster transaction speeds
- Higher liquidity with diverse trading pairs
- Robust customer support
Limitations:
- Vulnerability to hacks (centralized storage)
- Subject to regulatory restrictions
- Potential service interruptions

Decentralized Exchanges (DEX)
DEX platforms enable peer-to-peer cryptocurrency trading without intermediaries, operating via blockchain-based smart contracts.
Key Advantages:
- Enhanced security (no single point of failure)
- Greater user privacy (no KYC requirements)
- Resistance to government interference
Challenges:
- Steeper learning curve
- Lower liquidity (dependent on user-provided liquidity)
- Slower transaction times
