Centralised Exchange (CEX) Meaning

A centralised exchange (CEX) is a cryptocurrency trading platform operated by a centralized company that acts as an intermediary between buyers and sellers. CEXs manage user accounts, custody assets, maintain order books, and execute trades on behalf of users. Examples include Binance, Coinbase, Kraken, and OKX.

These platforms function similarly to traditional stock exchanges, offering high liquidity, fast execution, fiat on- and off-ramps, and advanced trading tools. Users deposit funds into the exchange’s wallets and trade using internal account balances rather than directly on-chain. The key advantage of CEXs is convenience.

They simplify trading for beginners, support customer service, and often provide regulatory compliance through KYC and AML procedures. Market depth and tight bid-ask spreads make them attractive for institutional traders. However, this convenience comes at the cost of custodial risk.

Users do not control their private keys; instead, the exchange holds assets on their behalf. This exposes users to risks such as hacks, insolvency, withdrawal freezes, or regulatory intervention.

The collapse of exchanges like FTX highlighted these systemic risks. CEXs also represent centralized points of control, meaning transactions can be censored or reversed internally.

As a result, many crypto participants follow the principle: “Not your keys, not your coins.” Despite these drawbacks, CEXs remain a dominant gateway into the crypto ecosystem, especially for fiat integration and institutional access.
