Built on Blockchain
Mostly on:
Ethereum
Powered by Smart Contracts

Fake projects
Malicious contracts
5. User Error

Freedom vs Protection
Key Insight
DeFi is not just a tool—it’s a new financial system
It enables:
Permissionless finance
Global access
Programmable money

👉 Think about this:
Would you trust code more than a bank? Why?
Final Thought
DeFi doesn’t just change how money works…it changes who controls it.
