Centralized Exchange (CEX)

What Is a Centralized Exchange?

A centralized exchange is a company-operated platform where users create accounts, deposit cryptocurrency or fiat currency, and trade using the exchange's matching engine. The exchange holds custody of deposited funds, maintains the order book, and processes withdrawals. CEXs provide features like advanced charting, margin trading, futures contracts, and fiat on-ramps that most DEXs do not offer.

To use a CEX, traders typically must complete KYC (Know Your Customer) verification, which involves submitting identity documents. This stands in contrast to DEXs, where no identity verification is required.

How CEXs Differ from DEXs

The fundamental difference is custody: on a CEX, the exchange controls your funds. On a DEX, you control your own wallet. CEXs offer faster execution speeds (microseconds vs. block confirmation times), deeper liquidity for major pairs, and more sophisticated trading tools. However, they also introduce counterparty risk — if the exchange is hacked, mismanages funds, or collapses (as with FTX in 2022), user funds may be lost.

For new token projects, listing on a major CEX is a significant milestone that provides access to millions of retail traders. However, CEX listings require applications, listing fees (often $100,000 to $1 million+), and compliance reviews. Most tokens begin trading on DEXs and pursue CEX listings as they grow.

CEX Listings and Token Growth

A CEX listing announcement often triggers significant price increases. Historical data shows that tokens listed on Binance see average price jumps of 30-100% in the first 24 hours. This "listing pump" occurs because CEX availability dramatically increases the potential buyer base. However, the price often retraces within days as early holders sell into the listing liquidity.
