TL;DR

Vitalik just crowned DeFi as Ethereum’s “killer app,” likening it to Google Search— the go-to engine that keeps everything else humming. In his latest post he argues DeFi has leveled up, weathered last cycle’s wild swings, and now offers a suite of low-risk, globally accessible products that power ETH collateral, drive revenue, and shape community culture.

This isn’t just hype—DeFi’s maturation aligns perfectly with Ethereum’s ethos of open access, economic fairness, and long-term value (hello, ETH as a store of value!). With DeFi at its core, Ethereum’s future looks less like a gamble and more like a well-oiled financial engine.
