Quick overview
- Decentralized finance (DeFi) is estimated to be about 30% toward mass global adoption, with institutional trials and real-world integrations on the rise.
- Regulatory clarity is seen as the primary barrier to DeFi's next growth phase, with clearer rules potentially boosting adoption to 50%.
- Nazarov predicts that DeFi could reach 100% adoption by 2030, driven by increasing institutional capital transitioning to blockchain systems.
- Current market trends show a significant increase in DeFi lending protocols, with total value locked rising from $53 billion to over $127 billion in 2025.
Decentralized finance may be far closer to mainstream use than many expect. According to Chainlink co-founder Sergey Nazarov, DeFi has already reached roughly 30% of the path toward mass global adoption, supported by accelerating institutional trials and expanding real-world integrations. In a discussion with MN Capital founder Michaël van de Poppe, Nazarov argued that regulatory clarity is now the single most important barrier standing between DeFi and its next major expansion phase.
DeFi—blockchain-based financial services built without intermediaries—could advance to 50% adoption once governments introduce clearer rules that help institutions understand why the technology is secure and reliable.
Nazarov’s perspective aligns with industry peers, including Curve Finance founder Michael Egorov, who has previously highlighted that DeFi’s largest obstacles stem from legal uncertainty, liquidity fragmentation and the need for clearer compliance pathways under KYC and AML standards.
Regulatory Clarity Seen as Key to Next Growth Phase
Nazarov suggested that regulatory momentum must begin in the United States before global adoption can accelerate. “A lot of governments follow what the U.S. does because they want to be compatible with the U.S. financial system,” he noted. A supportive regulatory model in the U.S. could therefore trigger a global domino effect.
🚨 Chainlink co-founder Sergey Nazarov drops bombshell: DeFi is ALREADY 30% toward MASS ADOPTION!
Key hurdles? Regs + institutional clarity. Once US greenlights it, domino effect hits globally—aiming for 70% with easy capital inflows, full 100% by 2030 via TradFi pie charts.

Meanwhile, Michael Selig, chief counsel for the crypto task force at the U.S. SEC, recently framed DeFi as an evolving concept, emphasizing that regulators should evaluate specific on-chain applications and their intermediaries rather than the label “DeFi” itself.
From Nazarov’s view, DeFi adoption will climb toward 70% once institutional investors receive a transparent, efficient method for allocating capital on-chain. Full adoption, he argued, will follow when DeFi’s capital base becomes sizable enough to be directly compared with traditional finance.
Key milestones Nazarov outlined:
- ~30% adoption today
- 50% adoption with clear legislation
- 70% adoption once institutions can allocate capital seamlessly
- 100% adoption when DeFi’s capital base rivals TradFi
Industry Momentum Builds Ahead of 2030 Forecast
Nazarov believes DeFi could reach 100% adoption by 2030, driven by the growing share of institutional capital transitioning to blockchain-based systems. He anticipates a future in which pie-chart comparisons show how much client and institutional money flows into DeFi versus traditional finance—a shift he says will signal the move from early adopters to mainstream users.
The market is already showing signs of acceleration. DeFi lending protocols have grown over 72% year-to-date, rising from $53 billion at the start of 2025 to more than $127 billion in cumulative total value locked, according to Binance Research. Increasing adoption of stablecoins and tokenized assets continues to strengthen that trajectory.
