Most of the money lost in DeFi in spring 2022 wasn't stolen by hackers. It evaporated because yield strategies quietly stopped working. April alone saw a $13 billion drawdown in the sector, a reminder that the biggest risks in decentralized finance often aren't the ones that make headlines.
The $13 Billion Drawdown
April 2022 was brutal for DeFi. The sector shed $13 billion in value, and the losses weren't concentrated in a single exploit or a dramatic flash crash. Instead, they came from yield strategies that had been running smoothly for months — until they weren't. These strategies, often built on complex interactions between lending protocols, liquidity pools, and leverage, can fail without warning. When they do, the money doesn't disappear in a dramatic heist. It just stops earning, and positions get liquidated.
The scale of the drawdown is striking. For context, that's more than many individual hacks have ever taken from the ecosystem. But because the losses were spread across dozens of strategies and protocols, they didn't get the same attention as a single exploit.
Why Yield Strategies Fail
The core problem, according to Solstice Finance's David Plisek, is that a headline yield number reveals almost nothing about whether it will hold under stress. A strategy might advertise 20% APY, but that number is often based on assumptions about market conditions that can shift in hours. When volatility spikes or liquidity dries up, the yield can collapse — and so can the principal.
Plisek argues that allocators need to look beyond the advertised rate. The real question isn't what the yield is today, but what it will be when the market turns. That's a lesson April taught the hard way. Many of the strategies that failed had been generating steady returns for months, lulling investors into a false sense of security.
What Allocators Should Ask
Plisek says allocators should ask four questions before committing capital to any DeFi yield strategy. He hasn't detailed those questions publicly, but his argument is clear: the due diligence process has to be more rigorous than checking a number on a dashboard.
The four questions, he contends, should force allocators to think about how a strategy behaves under stress, not just in calm markets. That means understanding the underlying mechanisms, the liquidity constraints, and the potential for cascading failures. It also means being honest about what happens when the yield stops — and whether the principal is safe.
Plisek's advice comes as the DeFi sector tries to rebuild trust after April's losses. The $13 billion drawdown was a wake-up call, but it wasn't a hack. It was a slow, quiet failure of strategies that looked good on paper. For allocators, the lesson is that a headline yield number is just the beginning of the conversation.
Plisek's four questions are meant to help allocators avoid the kind of quiet failures that drove April's drawdown. He hasn't published them, but his point is clear: in DeFi, the yield that looks good on paper can vanish without warning. The only way to protect capital is to ask the hard questions before the money goes in.
