In brief
- YFI creator Andre Cronje, Aave CEO Stani Kulechov and Synthetix founder Kane Warwick all spoke at this year’s Smart Contract Summit.
- They all expressed worry that DeFi was exploding due to greed.
- But they also said the underlying tools and technology were worth getting excited about.
The current explosion of decentralized finance (DeFi) is being driven by greed and its boom isn't sustainable, according to DeFi superstar and the creator of YFI, Andre Cronje.
We should also be worried about the huge amounts of money being made with yield farming—and DeFi protocols becoming too big.
These were some of the comments made by DeFi protocol at 2020’s Smart Contract Summit yesterday.
“I think the reason there is such a massive influx of money right now is because people are making money in insane amounts,” said Cronje when asked about what is driving the growth of DeFi by the co-founder of Chainlink, Sergey Nazarov.

YFI Breaks Past $20,000, Surpassing Bitcoin's All-time High
YFI, the governance token that powers decentralized finance protocol yEarn, or yearn.finance, today leapt past $20,000, surpassing Bitcoin's all-time high. The cost of a single YFI token is $22,686, as of press time. It has increased by 25% in the past 24 hours, according to data from metrics site CoinMarketCap. YFI is a governance token, meaning that holders can pledge it to cast their vote on policy proposals that influence the future of the yEarn network. But YFI is also held as a speculativ...
He said that people snapping up and selling governance tokens—assets designed to allow people to make decisions on DeFi protocols—have led to this boom.
“It’s not a sustainable part of DeFi,” he said, adding that valuable protocols in the DeFi space—such as Synthetix, Compound and Chainlink—would still be around when the “greed phase is over.”
Aave co-founder and CEO Stani Kulechov also shared Cronje’s pessimism: “What I’m scared of is that while DeFi protocols are growing a lot, they are starting to think how they can accumulate all the wealth,” he said. “They’re starting to become the banks they basically tried to escape.”
But he added that he did like how people are using Aave—a protocol that lets you earn interest on deposits and borrow assets—and said the best way to avoid the problem of DeFi protocols getting too big would be for different protocols to “work together seamlessly.”
Also on the panel was Kane Warwick, the founder of synthetic asset platform, Synthetix.
Warwick said that while he agreed that the boom in DeFi was being in part driven by a token boom, there was an “underlying, powerful force at play.”
“We’re all on the ground floor of this redesign of traditional finance systems into new decentralized systems,” he said. “Anyone who participates will reap significant rewards if they allocate their time and capital.”
DeFi has exploded with popularity this year. Almost $9 billion in cryptocurrency is now locked in the industry’s smart contracts—a number that has doubled since the start of July, according to data analytics site DeFi Pulse.

DeFi Token Spinoff Rises 222% as YFI Hits $26,000
It's the latest twist in a crazy day: YFII, the spinoff of—and stick with us here—YFI, has risen 222% in the past day, from $1,154 to its current price, $3,781. YFII's big day coincides with a record-breaking one for YFI, which recently surpassed $26,000, far more than Bitcoin's all-time high, and more than double its current price of $11,507. Confused? A primer: YFI is a governance token of yEarn, or yearn.finance, a decentralized finance (DeFi) app that aggregates the yields of various DeFi le...
The market cap of DeFi has also blown up—sitting at $17.6 billion according to today’s CoinGecko data. And the surge in investment has led some to believe it may be a bubble on the verge of bursting.
The CEOs agreed at the summit that what is being built with the current DeFi protocols is exciting. "Money legos"—allowing developers to put different existing DeFi tools together to make new ones—was one hot topic.
Cronje said it was “awesome.”
“So often you see people build stuff you could never have envisioned—like someone launches a product that uses your platform and you’re like, how the hell could they think of this? Then you play with it and you think it’s cool.”
“There’s much less of a plan and a lot of exploratory fun.”
