Lesson 4
What is DeFi?
Decentralized finance – banking without banks
DeFi stands for Decentralized Finance. DeFi replaces traditional financial services with smart contracts on the blockchain.
Loans, savings, exchange, insurance: everything a bank offers can happen in DeFi without a bank – 24/7, worldwide, for anyone with internet access.
The most well-known DeFi applications are decentralized exchanges (DEX) like Uniswap, lending protocols like Aave and stablecoin platforms.
DeFi offers opportunities but also risks: smart contract bugs and high volatility have led to losses in the past. Always do your own research.
