Let’s talk about something that keeps popping up in crypto circles: “You can earn passive income with stablecoins.” It sounds almost too good to be true. Hold a digital dollar, sit back, and watch it grow. But before you rush to move your savings into USDC or DAI, it’s worth slowing down and asking: what’s really going on here?
First, let’s clear up a common misconception. Stablecoins themselves don’t magically generate yield. If you leave USDT sitting in your wallet, it will stay exactly the same amount for years, just like cash under a mattress. The yield doesn’t come from the token; it comes from what you do with it. In other words, “passive” is a bit of a misnomer. True passivity would mean doing nothing and still earning returns. But in practice, you have to actively deploy your stablecoins into systems that put them to work.
So where does this yield actually come from? And more importantly, is it safe?
One of the most straightforward ways to earn yield is through decentralized lending protocols like Aave or Compound. You deposit your stablecoins, they get lent out to borrowers, often traders using leverage, and part of the interest those borrowers pay flows back to you. Right now, typical annual yields on these platforms range from 3% to 9%. During promotional periods, when protocols are trying to attract liquidity, you might even see rates climb to 10% or 12%. These platforms are relatively user-friendly, your funds are usually accessible on demand, and within the DeFi world, they’re considered lower-risk options. That said, “lower risk” doesn’t mean “no risk.” More on that later.
Then there’s a newer category I like to think of as “stablecoins that lay eggs.” These aren’t just placeholders for dollars. They’re designed to automatically accrue yield. Take sDAI, for example, issued by MakerDAO. When you convert your DAI into sDAI, you’re essentially buying a share of Maker’s surplus buffer, which includes income from U.S. Treasury bills and other real-world assets. The current yield sits around 5% to 8% annually. Similarly, sUSDe from Ethena Labs offers yields between 8% and 15%, depending on market conditions. But here’s the twist: sUSDe doesn’t rely on lending. Instead, it uses a delta-neutral strategy, simultaneously holding long positions in Ethereum and short positions in perpetual futures, to capture funding rate spreads without betting on price direction. It’s clever, but it’s also more complex and tied to derivatives markets, which adds layers of risk …
