The DEfi project is a decentralized finance developed by blockchain technology, which is different from previous finance. In the past, finance required the intervention of financial companies. Decentralized finance is built on the blockchain and relies on contracts. Traditional centralized finance, which uses instruments such as exchanges, banks, or financial companies for financial transactions, suffers from perceived disruption. On the other hand, DEfi is a decentralized financial product that is built on the blockchain without human interference. It all relies on smart contracts to run. Be
