DeFi Explained: What It Is, How It Works, and Why It Matters
When you hear DeFi, short for decentralized finance, a system that lets people lend, borrow, and trade money without banks or middlemen. Also known as decentralized finance, it runs on blockchains like Ethereum and Celo, using smart contracts, self-executing code that automatically handles agreements when conditions are met instead of humans.
DeFi isn’t about apps you download—it’s about protocols you interact with directly. Think of it like building your own bank using open-source software. You can deposit crypto into a pool and earn interest, swap one token for another on a DEX, a decentralized exchange that doesn’t hold your funds, or even lend money to strangers across the world—all without a credit check. But it’s not magic. That liquidity provision, the act of supplying crypto to trading pools so others can swap tokens you see advertised? It comes with hidden risks like impermanent loss, where your investment can lose value even if prices go up. And if the code has a flaw? Your money can vanish overnight.
DeFi isn’t just for traders. It’s changing how people in countries with unstable banks access loans, how artists earn from their work, and how apps reward users with real tokens instead of points. But most of what you see online—especially those "earn 500% APY" ads—are either scams or risky gambles. The real DeFi projects, like Moola Market on Celo or RadioShack’s routing protocol, focus on solving real problems: low fees, fast trades, mobile access. And while some platforms like Shadow Exchange on Sonic are pushing new limits, others, like KyberSwap Classic, show how thin liquidity can kill even the best ideas.
What you’ll find below isn’t hype. It’s the truth about DeFi as it actually exists in 2025: the good, the broken, and the outright fake. From how impermanent loss eats into your returns to why a $34 billion fine on Upbit changed everything for DeFi compliance, these posts cut through the noise. You’ll learn which protocols still work, which exchanges are scams, and how to protect your money in a world where the rules are written in code, not courts.
