The pitfalls of chasing yield on stablecoin lending protocols

Been thinking a lot about the early days of DeFi and stablecoins, specifically around 2020-2021. One of the biggest lessons I learned, and frankly, a mistake that cost me a good chunk of capital, was the aggressive pursuit of yield on various stablecoin lending protocols. At the time, rates on something like $USDT or $USDC would sometimes hit double-digits, especially on newer, less established platforms. The allure was obvious: risk-free (or so it seemed) passive income on what were supposedly pegged assets.

The mistake wasn't necessarily in the concept of stablecoin lending itself, but in the lack of due diligence on the underlying platforms and the overconfidence in their ability to maintain those yields without significant risk. I remember chasing a particularly high rate on a relatively unknown protocol, moving a significant portion of my $USDC there, only for it to be exploited a few months later. The recovery was partial at best. It hammered home that even with stablecoins, the counterparty risk, smart contract risk, and even oracle risk are very real. It wasn't 'free money,' and the market always finds a way to balance risk and reward. Now, my approach is far more conservative, prioritizing audited, established protocols with a proven track record, even if the yields are a fraction of what they once were.
