#CEXvsDEX101 In cryptocurrencies, "DEX" refers to a "Decentralized Exchange," while "CEX" is a "Centralized Exchange." The main difference lies in how transactions are conducted. DEXs allow direct trading between users without a central authority, while CEXs operate as intermediaries, matching buy and sell orders.
DEX (Decentralized Exchange):
Decentralization:
There is no central entity controlling transactions. Orders are processed through smart contracts on blockchains.
User control:
Users maintain control over their private keys and thus over their cryptocurrencies.
Security:
Security depends on the protocol and the blockchain used, but generally offers more protection against hacks and fraud.
Privacy:
Trading is more private, as disclosing personal information to a central authority is not required.
Costs:
Transaction costs can be lower because there are no intermediaries.
CEX (Centralized Exchange):
Centralization: A company controls the platform and the transactions.
Easier onboarding: Usually, the registration and onboarding process is simpler.
High liquidity: CEXs offer higher liquidity, facilitating the trading of large volumes of cryptocurrencies.
Customer support: CEXs typically provide more robust customer support.
Custody: Users must deposit their cryptocurrencies on the platform to trade, which may pose custody risks.
KYC/AML requirements: CEXs usually require identity validation and information to comply with regulations.
