What Is DeFi?

What you’ll learn

• •DeFi rebuilds financial services — trading, lending, borrowing, earning interest — using public smart contracts instead of banks and brokers.
• •Open access means just a wallet and internet connection, with no application, credit check, or approval process.
• •DeFi runs continuously and sets terms algorithmically and transparently, instead of fixed hours and hidden fine print.
• •That same openness removes deposit protection and any support line — you're relying entirely on the contract's code being correct and secure.
• •Protocols plug into each other ('money legos'), so composability is a strength, but risk can travel between linked protocols too.
• •This week covers DEXs/AMMs, liquidity pools, staking, yield farming, lending/borrowing, and stablecoins in turn.
