The sustainability of high-yield products in decentralized finance (DeFi) is questionable. These products often promise outsized returns through mechanisms like yield farming or liquidity provision, driven by speculative token incentives and leverage. However, such yields are frequently unsustainable due to market volatility, impermanent loss, and reliance on continuous capital inflows. Smart contract risks, regulatory uncertainties, and potential exploits further threaten stability. While some projects with robust fundamentals may offer more sustainable yields, many high-yield opportunities collapse when market conditions shift or incentives dry up. Investors must weigh risks against rewards, as chasing high returns often leads to significant losses in DeFi’s nascent and volatile ecosystem. Due diligence and risk management are critical for navigating these products.
