  "topic": "DeFi users / active addresses over time (2020 to 2026)",
  "summary": "DeFi participation, measured by cumulative unique wallet addresses, grew from roughly 1 million (Dec 2020) to over 330 million by mid-2026 according to Richard Chen's widely cited Dune Analytics dashboard. CRITICAL CAVEAT: that dashboard counts CUMULATIVE unique addresses ever to interact with tracked DeFi apps across all chains, and explicitly notes 'Users = unique addresses; since a user can have multiple addresses, these graphs are overestimates.' The number of real PEOPLE is far smaller. a16z's State of Crypto reports estimate only 30-70 million monthly ACTIVE crypto users worldwide (out of ~716 million crypto owners), and that DeFi accounts for roughly a third of daily on-chain activity. Total crypto monthly active ADDRESSES (all activity, not just DeFi) peaked at an all-time high of ~220 million in September 2024 per a16z, then settled to ~181 million by 2025 (down 18% YoY) as the Solana-driven memecoin surge cooled. Headline takeaways: (1) cumulative DeFi addresses grew ~330x from 2020 to 2026; (2) addresses are NOT people and overstate the user base substantially; (3) growth accelerated sharply in 2024-2025, driven heavily by low-fee chains (Solana, Base, BNB, Tron). Different methodologies produce very different numbers, so cross-source comparison requires care.",
