Crypto basics
What is DeFi?
DeFi (decentralized finance) is financial services — trading, lending, earning — run by smart contracts instead of a company, directly from your wallet.
Why it matters for your safety
DeFi puts you in control, which also means you are responsible for safety. The main risks are fake front-ends and leaving token approvals open — verify URLs and revoke unused approvals.
