For years, Ethereum has weathered waves of skepticism questioning whether its flagship use case—decentralized finance (DeFi)—holds genuine value. Suddenly, one of the main drivers of this criticism has become the network's own founder, Vitalik Buterin.
"The applications I want to see are (i) useful in a sustainable way, and (ii) do not compromise principles (permissionlessness, decentralization, etc.)," Vitalik wrote on Twitter Sunday while discussing his views on DeFi.
He praised examples such as decentralized exchanges, stablecoins, and Polymarket, but criticized unsustainable products that emerged during the 2021 yield farming craze.
Vitalik’s latest comments respond to growing frustration within the Ethereum community, which feels that he—being the most influential voice in the ecosystem—has only “barely tolerated” DeFi, while advocating for other niche use cases that haven’t achieved similar product-market fit.
"One of his biggest mistakes over the past five years has been underestimating the importance of DeFi," Kain Warwick, founder of Synthetix, said on a podcast Friday, accusing Buterin of moralizing at other industry leaders and telling them to “stop doing DeFi.”
"He’s been trying really hard to make non-DeFi things work," Warwick continued. "The reality is, the market is right—and you’re wrong."
After the podcast aired, many expressed disappointment upon learning that Vitalik does not broadly welcome or encourage DeFi on Ethereum, except for the specific exceptions he mentioned. On the other hand, some staunch Bitcoin supporters reacted with unexpected delight to Vitalik’s remarks, finding common ground with him in opposing DeFi yield schemes.
As Vitalik later clarified, his criticism even extends to DeFi protocols that provide returns to token holders through borrower and trading fees, rather than via token inflation or “Ponzi economics.”
"It feels like a self-devouring snake: the value of crypto tokens lies in your ability to earn yield from them, and that yield comes from… people paying by trading crypto tokens," he wrote.
Even over-collateralized lending markets using ETH as collateral—such as Aave—are seen by Vitalik as limited, because the value and existence of these markets ultimately depend on downstream outcomes of the ETH market itself.
"I would really love to see a story where the source of yield is rooted in something external," he said. "I’ve heard some possible candidates… I’m open to hearing more ideas like that."
