Stablecoins in DeFi: How They Keep Crypto Stable and Where They Go Wrong
When you trade crypto, you don’t want your money to swing 30% in a day. That’s where stablecoins in DeFi, digital tokens pegged to real-world assets like the US dollar to reduce volatility. Also known as pegged tokens, they’re the glue holding together decentralized finance. Without them, DeFi would be chaos—every swap, loan, or yield farm would carry wild price swings. But here’s the truth: not all stablecoins are created equal. Some hold real cash reserves. Others rely on algorithms that can, and have, collapsed overnight.
The biggest warning sign? The UST collapse, the $60 billion failure of Terra’s algorithmic stablecoin in 2022 that dragged down entire DeFi ecosystems. It wasn’t a hack. It was a design flaw. When users lost faith, the peg broke, and the whole system unraveled. That’s why you need to know the difference between USDT, Tether’s dollar-backed token, the most widely used stablecoin with real reserves and heavy scrutiny, and the dozens of lesser-known tokens promising stability with no audit, no proof, and no track record. Stablecoins in DeFi aren’t just tools—they’re trust anchors. Break one, and you risk losing everything stacked on top of it.
That’s why the posts below dig into the real stories behind the hype. You’ll find deep dives on how stablecoins in DeFi are used in yield farms, how they get depegged, and why some tokens pretending to be stable are just gambling chips in disguise. We cover the technical risks, the scams, and the rare ones that actually deliver on their promise. No fluff. Just what you need to know before you lock your funds into a protocol that depends on a stablecoin to hold its value.
