In the fast-growing world of cryptocurrency, two main types of exchanges help users buy, sell, and trade digital assets: Centralized Exchanges (CEXs) and Decentralized Exchanges (DEXs).
This guide will help you understand the key differences, benefits, and risks of each type. Whether you're a beginner or brushing up your knowledge — this is your go-to explainer.
🔍 What Is a Centralized Exchange (CEX)?
A Centralized Exchange (CEX) is a platform operated by a company that acts as a middleman between buyers and sellers. You must create an account and trust the exchange to hold your funds and process transactions.
📊 Examples:
Binance
Coinbase
Kraken
🌐 What Is a Decentralized Exchange (DEX)?
A Decentralized Exchange (DEX) allows users to trade directly with one another without intermediaries. It uses smart contracts on a blockchain to automatically match and process trades.
🧱 Examples:
Uniswap
PancakeSwap
SushiSwap
