A Decentralized Exchange (DEX) is a type of cryptocurrency exchange that operates without a central authority. DEXs allow users to trade directly from their wallets through smart contracts or other decentralized protocols. They typically don't require identity verification (KYC) and give users full control over their funds throughout the trading process, eliminating counterparty risk associated with centralized exchanges.

Frequently Asked Questions
How do DEXs differ from centralized exchanges?
DEXs operate without a central authority, allow users to maintain custody of their funds, don't require KYC verification, and execute trades through smart contracts rather than matching engines. Centralized exchanges act as intermediaries, require account creation and KYC, and hold user funds in their custody.
Are DEXs safer than centralized exchanges?
DEXs eliminate counterparty risk (exchange hacks or insolvency) since users maintain control of their funds. However, they introduce smart contract risk and may be more complex to use. The safety depends on your specific concerns - DEXs protect against exchange failures but require greater user responsibility.
What are the downsides of using DEXs?
DEXs often have higher transaction fees (especially on Ethereum), may have lower liquidity for some trading pairs, typically offer fewer advanced trading features, can be slower than centralized alternatives, and require users to manage their own wallet security.
