A decentralized exchange (DEX) differs from a centralized exchange in several ways. Here are some key differences:

  1. Centralization vs. decentralization: A centralized exchange is owned and operated by a single entity, which has full control over the exchange infrastructure and the user's funds. On the other hand, a DEX operates on a decentralized network, often utilizing blockchain technology, where no central authority has control over user funds.
  2. Intermediaries and custody: Centralized exchanges act as intermediaries between buyers and sellers, holding custody of user funds. Users need to trust the exchange with their assets, and transactions are settled through the exchange's internal ledger. In a DEX, trades occur directly between users without the need for intermediaries. Users maintain control over their funds and execute trades through smart contracts on the blockchain.
  3. Trust and transparency: Centralized exchanges require users to trust the platform with their funds and transactions. The exchange is responsible for maintaining security, and users are vulnerable to hacking, fraud, or mismanagement. Conversely, DEX platforms aim to offer more transparency and trustlessness. Users have complete control over their funds, reducing the chances of hacks or insider manipulation. Transactions on a DEX are recorded on the public blockchain, providing transparency to all participants.
  4. Privacy: Centralized exchanges often require users to submit personal identification and undergo Know Your Customer (KYC) procedures for regulatory compliance. DEX platforms can provide more privacy as they may not require KYC information, depending on their design. However, some DEXs might still follow KYC procedures if they interact with fiat currencies or integrate with centralized components.
  5. Liquidity: Centralized exchanges typically offer more liquidity due to their vast user base and market-making activities. DEXs might face liquidity challenges initially, but various protocols and mechanisms have been developed to address this issue, such as decentralized liquidity pools, automated market makers, and incentivized liquidity provision models.
  6. Governance: Due to their decentralized nature, DEX platforms often enable users to participate in governance decisions. Token holders or liquidity providers may participate in protocol upgrades, fee structures, or adding new assets. Centralized exchanges, on the other hand, have centralized decision-making authority controlled by the exchange's owners or administrators.


In summary, while centralized exchanges offer convenience, liquidity, and regulatory compliance, DEX platforms prioritize decentralization, security, transparency, and user control over funds.
