CeFi encompasses a wide range of financial services, including cryptocurrency exchanges, lending and borrowing platforms, and wallets that require users to trust a central authority with their funds. In CeFi, the managing organization acts as an intermediary, carrying out transactions and maintaining user accounts while providing services like trading, investment options, and liquidity pools. Examples include platforms like Coinbase, Binance, and Kraken where users can deposit funds and engage in trading but must comply with the rules and regulations set by these centralized entities.
