Self-Custody Features in Decentralized Exchanges (DEXs) allow users to maintain complete control over their private keys and funds. This feature eliminates the need for third-party custodians, thereby enhancing security and privacy. Users can manage their assets directly from their wallets, ensuring that they are the sole owners of their funds. This feature is crucial in the decentralized finance (DeFi) ecosystem, where trustless transactions and user autonomy are paramount. By utilizing self-custody, users can engage in trading, lending, and other financial activities without the risks associated with centralized exchanges, such as hacks or insolvency.
