A decentralized crypto exchange (DEX) enables peer-to-peer cryptocurrency trading without relying on a central authority. Transactions are executed using smart contracts, ensuring transparency and user control over funds. Unlike centralized platforms, DEXs offer enhanced privacy, reduced risk of hacking, and global accessibility. Users retain custody of their assets, making DEXs popular among security-conscious traders. These exchanges support various tokens and often operate on blockchain networks like Ethereum, BNB Chain, or Solana. As the demand for trustless financial systems grows, DEXs play a vital role in the decentralized finance (DeFi) ecosystem.
