DeFi crypto: Top lending platforms, DEXs, and real-world use cases in 2025

When you hear DeFi crypto, a system of financial services built on blockchains without middlemen like banks. Also known as decentralized finance, it lets you earn interest, borrow cash, or trade tokens—all from your wallet, with no approval needed. This isn’t theory. In 2025, real people are using DeFi to earn 5% to 12% APY on stablecoins, swap tokens with near-zero fees, and access loans without credit checks.

At the heart of DeFi crypto are decentralized exchanges, platforms like Solarbeam and SundaeSwap that let you trade directly from your wallet without handing over control. Unlike centralized exchanges, these don’t hold your funds. They use smart contracts to match trades automatically. Then there’s DeFi lending platforms, like Aave, Compound, and MakerDAO, where you deposit crypto to earn yield or borrow against it as collateral. These aren’t just for traders. Farmers use them to unlock liquidity from idle assets. Investors use them to hedge against volatility. Even people in countries with strict banking rules, like Cambodia, are turning to DeFi to move value when traditional systems block them.

But not all DeFi is equal. Some platforms, like MilkshakeSwap, have zero liquidity and no updates—just empty promises. Others, like Thruster v3, are built for experts on niche chains like Blast. And wrapped assets like WBTC? They let Bitcoin move across chains, but they rely on centralized custodians, which defeats part of the point. The key is knowing what’s live, what’s risky, and what’s just a ghost project. That’s why this collection dives into real examples: the DEXs that actually work, the lending protocols with real APYs, and the tokens tied to functional tools—not memes.

You’ll find reviews of platforms you can use today, breakdowns of how order books on DEXs beat AMMs for precision trading, and warnings about scams hiding behind fake airdrops. No fluff. No hype. Just what’s working, what’s broken, and what you should avoid in 2025. Whether you’re earning yield, swapping tokens, or just trying to understand why DeFi matters, these posts give you the facts to move forward without losing money.
