What is a DEX (Decentralized Exchange)?

The short answer

A crypto exchange that runs on smart contracts rather than a company matching buyers and sellers.

DEXs typically don’t require identity verification and let you trade directly from your own wallet, but they also come without the customer support and regulatory protections a centralised exchange might offer.
