Examples of Decentralized Crypto Exchanges

Decentralized crypto exchanges (DEXs) are platforms that allow users to trade cryptocurrencies directly with one another without the need for an intermediary or central authority. Unlike centralized exchanges, which require users to deposit their assets into the platform's custody, DEXs operate on blockchain technology and smart contracts, ensuring greater security and control for users. In this comprehensive guide, we will explore some prominent decentralized exchanges, their unique features, advantages, and potential drawbacks.
