A cryptocurrency exchange operated by a central organization that holds users' funds and manages trades.
A Centralized Exchange (CEX) is a cryptocurrency trading platform operated by a company or organization that controls the platform’s infrastructure, order books, and custody of user funds. CEXs act as intermediaries, handling deposits, withdrawals, and trade execution on behalf of their users.
They are the most common entry point for new crypto traders due to their ease of use, high liquidity, and wide selection of trading products.
How a CEX Works
On a centralized exchange:
Users deposit funds into exchange-controlled wallets.
The platform manages internal order books and matches trades.
The exchange provides customer support, security, and compliance services.
Trades occur off-chain within the exchange’s system, allowing for fast execution and low cost.
Key Features of CEXs
High liquidity: Large trading volumes enable tight spreads and rapid order execution.
User-friendly interfaces: Simple dashboards for buying, selling, and portfolio management.
Advanced trading tools: Futures, margin trading, staking, lending, and options.
Custodial services: Exchange holds private keys for users.
Regulatory compliance: KYC/AML requirements depending on jurisdiction.

Risks and Considerations

Summary
