This refers to financial services that are run by a central company, like a crypto exchange.
CeFi (Centralized Finance) refers to a financial system in which a centralized company or institution acts as a trusted intermediary to facilitate financial services and cryptocurrency transactions.
CeFi is essentially the bridge between the traditional financial system and the world of cryptocurrency. Services like centralized exchanges (CEXs) are a prime example of CeFi. When you use a CEX like Coinbase or Binance, you are entrusting your digital assets to that company. They take custody of your funds and manage the order books and transactions. This provides a user-friendly experience, access to customer support, and the ability to easily convert between fiat-currency and crypto.
This model stands in contrast to DeFi, where services are offered on the blockchain through automated smart-contracts and do not require a central intermediary. In a DeFi system, you maintain full control of your assets in a non-custodial wallet. While CeFi offers a more familiar and secure experience for beginners, it comes with a risk of centralized failure, as your assets are subject to the company's policies and security.
CeFi plays a crucial role in the crypto ecosystem by providing a gateway for new users. It simplifies the process of buying, selling, and holding crypto, making it more accessible to a wider audience. However, the centralization that makes it easy to use also introduces risks that run counter to the core principles of decentralization.
