Centralized Exchange (CEX)

What is a Centralized Exchange (CEX)?

A Centralized Exchange (CEX) is a cryptocurrency exchange platform that operates as an intermediary between buyers and sellers. It's a company that facilitates cryptocurrency trading, operating similarly to traditional stock exchanges but for digital assets. CEXs are centrally managed and operated by a single organization.

Key Features of Centralized Exchanges

1. Order Matching: Automatically match buy and sell orders.

2. Custody: Hold and manage user funds and cryptocurrencies.

3. User Interface: Provide user-friendly platforms for trading.

4. Liquidity: Often offer higher liquidity than decentralized alternatives.

5. Fiat On-ramps: Many provide ways to buy crypto with traditional currencies.

How Centralized Exchanges Work

The typical process of using a CEX involves:

1. Registration: Users create an account and verify their identity (KYC).

2. Deposit: Funds are deposited into the exchange's custody.

3. Trading: Users place buy or sell orders on the exchange's order book.

4. Order Matching: The exchange matches orders between buyers and sellers.

5. Withdrawal: Users can withdraw funds or cryptocurrencies to external wallets.
