Chainlink co-founder Sergey Nazarov believes decentralized finance (DeFi) is progressing faster than many realize, estimating the industry is already 30% of the way toward global adoption. However, he emphasizes that the next major step depends heavily on regulatory clarity, institutional confidence, and a more mature infrastructure that can support billions in capital.
In a recent conversation with MN Capital founder Michaël van de Poppe, Nazarov outlined how DeFi could reach 100% adoption by 2030—a forecast that is rapidly gaining attention across the industry.
DeFi Adoption Accelerates but Regulatory Barriers Remain
According to Nazarov, DeFi has already demonstrated its value in enabling peer-to-peer financial services without centralized intermediaries. Yet, despite growing use cases, the industry still faces regulatory and institutional resistance.
Nazarov said he expects DeFi to achieve “50% global adoption” once major jurisdictions—especially the United States—provide clearer rules that explain why DeFi systems are safe, reliable, and comparable to traditional finance (TradFi).
His view aligns with other industry leaders. Curve Finance founder Michael Egorov has previously warned that regulatory uncertainty, compliance requirements like KYC and AML, and concerns around liquidity and security remain the biggest obstacles.
These barriers are particularly important to institutions, which require legal and operational clarity before deploying large pools of capital into DeFi protocols.
Why US Approval Could Trigger a Global Domino Effect
Nazarov believes the United States will play a critical role in shaping the next wave of global adoption. Most governments, he said, want to remain interoperable with the US financial system, meaning American regulatory clarity could trigger a domino effect worldwide.
This perspective was reinforced recently by Michael Selig, chief counsel for the SEC’s crypto task force, who noted that regulators need to evaluate on-chain applications based on their structure and whether intermediaries are involved.
According to Nazarov, once the US provides a clear framework for compliant DeFi activity, other countries will likely follow quickly, boosting cross-border institutional participation.
Institutional Pathways Could Push DeFi to 70% Adoption
Another major milestone on the path to mass adoption, according to Nazarov, will occur when institutions can easily deploy both their own capital and clients’ capital into DeFi systems.
This requires:
-
Trustworthy custody solutions
-
Secure and scalable smart-contract infrastructure
-
Regulatory clarity
-
Transparent, auditable on-chain systems
Once these conditions are met, Nazarov predicts that global DeFi adoption will climb to 70%, driven by pension funds, asset managers, banks, and fintech companies allocating capital into on-chain products.
The rapid rise of tokenized assets and stablecoins supports this trend. Institutional adoption of on-chain treasury products, in particular, has increased sharply throughout 2025—as highlighted by several major market research firms.
Full Adoption Could Arrive by 2030, Says Nazarov
Nazarov believes DeFi will hit full maturity when the proportion of institutional and retail funds locked in decentralized systems can be meaningfully compared to traditional finance.
“In 2030, we’ll have pie charts showing the percentage of institutional capital held in DeFi versus TradFi,” he said, adding that once these percentages grow large enough, mainstream acceptance becomes inevitable.
He compared the trend to the growing share of stablecoins relative to the overall treasury market—still small, but expanding at a rate that forces institutions to pay attention.
“As these percentages rise, people will begin realizing that significant institutional capital has already shifted on-chain,” he said. “That’s when DeFi moves from early adoption to mass adoption.”
DeFi Lending Already Surging in 2025
Momentum is already visible across key DeFi sectors. According to Binance Research, DeFi lending protocols have expanded by more than 72% year-to-date, climbing from $53 billion in early 2025 to over $127 billion in total value locked.
This surge is driven by:
-
Growth of stablecoin usage
-
Expansion of tokenized real-world assets (RWAs)
-
New institutional custody solutions
-
Improved blockchain scalability
These trends illustrate the broader shift that Nazarov expects to accelerate sharply over the next few years.
The Road to Mass Adoption Is Set, but Challenges Remain
While DeFi is progressing quickly, Nazarov stresses that the journey to 100% adoption requires solving regulatory and institutional concerns—particularly around security, transparency, and AML/KYC compliance.
Still, with global on-chain finance growing at its fastest rate ever, the Chainlink founder remains confident that the next five years will be transformational.
If Nazarov’s timeline holds, DeFi may transition from a niche technology to a mainstream global financial system by 2030, fundamentally reshaping how capital moves across markets worldwide.
