Intro to DeFi & Stablecoins
Decentralized finance rebuilds trading, lending, and saving without banks — using smart contracts. It’s genuinely useful and genuinely risky. Here’s the honest introduction.
DeFi vs. traditional finance
| Traditional (CeFi) | DeFi | |
|---|---|---|
| Who runs it | Banks & companies | Smart contracts, no middleman |
| Access | Approval, hours, borders | Open to anyone with a wallet |
| Risk | Institutional failure, fees | Code bugs, exploits, volatility |
Common building blocks: DEXs (swap coins directly from your wallet), lending (earn or borrow against crypto), and stablecoins (dollar-pegged coins used as steady units of value).
Yield always has a catch
High advertised returns mean high risk — smart contract failure, de-pegging, or outright scams. If you can’t explain where the yield comes from, don’t put in money you can’t lose. (Educational, not advice.)
Key takeaways
- DeFi replaces intermediaries with smart contracts — open but riskier.
- DEXs, lending, and stablecoins are the core pieces.
- Understand the source of any yield before chasing it.
