What is DEX? DEX stands for decentralized exchange. It is a crypto exchange that lets users trade tokens directly from their wallets without relying on a central company to hold their funds.
DEX Explained A DEX is like a marketplace for trading crypto tokens.
On a regular exchange, a company usually holds your funds and helps match buyers with sellers.
On a DEX, users connect their own wallets and trade through smart contracts. The exchange does not need to hold the user’s crypto.
This gives users more control over their assets, but it also means they are responsible for checking transactions, wallet safety, and token risks.
