Decentralized Crypto Exchanges: A Comprehensive Guide

Decentralized crypto exchanges (DEXs) represent a revolutionary shift in the cryptocurrency trading landscape. Unlike centralized exchanges (CEXs) that are managed by a central authority, DEXs operate on a peer-to-peer basis, allowing users to trade directly with one another. This guide explores the top decentralized exchanges, their key features, benefits, and potential drawbacks.

1. Introduction to Decentralized Exchanges

Decentralized exchanges facilitate trading without relying on a centralized intermediary. They operate through smart contracts on blockchain platforms, ensuring transparency and security. Users maintain control of their private keys and funds, minimizing the risk of hacks and fraud compared to CEXs.
