Navigating the world of decentralized finance can be complex. This guide breaks down the best decentralized exchanges (DEXs) to help you trade cryptocurrencies safely and efficiently directly from your wallet.
What is a Decentralized Exchange?
A decentralized exchange is a platform that allows peer-to-peer cryptocurrency trading without intermediaries. Unlike centralized exchanges, DEXs enable users to retain control of their private keys and funds throughout the trading process, enhancing security and privacy while typically offering lower fees.
