Decentralized Exchange

Definition ∞ A Decentralized Exchange (DEX) is a cryptocurrency trading platform that operates without a central intermediary or custodian. Users trade digital assets directly from their own wallets through automated market makers or peer-to-peer matching engines. This model prioritizes user control over funds and resistance to censorship.
Context ∞ Decentralized Exchanges are a focal point in crypto news due to their role in facilitating open and permissionless trading of digital assets. Developments related to DEX adoption, new trading features, liquidity provision, and regulatory scrutiny are frequently reported, highlighting their growing significance in the decentralized finance (DeFi) landscape.
