A dex exchange (или decentralized exchange) is a platform for trading cryptocurrencies that operates on a decentralized blockchain network. Unlike centralized exchanges, dex exchanges do not store users' funds or personal data, providing increased security and privacy. Users retain control over their assets and interact with the exchange through smart contracts.

DEXs offer a significant advantage by eliminating single points of failure, thereby reducing the risk of hacks and fraud. They empower users with full control over their assets, making the trading experience more secure and transparent.
