What is CeFi?

Crypto financial services operated by centralized companies that custody user funds, as opposed to decentralized protocols. Lygos was specifically designed to solve CeFi's fundamental flaw: counterparty risk. While CeFi lenders custody your Bitcoin (and may rehypothecate it), Lygos's DLC architecture ensures your collateral never enters Lygos's custody. You get the professional lending experience of CeFi with the trustlessness of a Bitcoin-native protocol.

Full Definition

Centralized Finance (CeFi) refers to crypto companies that offer financial services (lending, borrowing, trading, yield) through centralized platforms where the company custodies user assets. CeFi platforms include exchanges (Coinbase, Binance), lenders (Celsius, BlockFi, Nexo, Ledn), and brokerages. CeFi offers familiar user experiences and customer support, but introduces counterparty risk: if the company mismanages funds, becomes insolvent, or faces regulatory action, user assets may be at risk. The 2022 CeFi crisis (Celsius, FTX, BlockFi, Voyager all collapsed) demonstrated this risk catastrophically, with billions in customer assets frozen or lost.
