  "topic": "Total DeFi TVL over time",
  "summary": "Total Value Locked (TVL) across all of DeFi grew from effectively zero in 2018-2019 (~$0.6B end-2019) to ~$15B at the end of 2020 during 'DeFi Summer', then exploded to an all-time high of ~$177.5B on 2021-11-09 (widely cited as ~$178-180B) during the 2021 bull market. The 2022 collapse — driven by the Terra/LUNA implosion (May 2022), Three Arrows Capital, Celsius, and FTX (Nov 2022) — crushed TVL ~78% to a year-end-2022 value of ~$38B, with the cycle low around ~$38-42B in late 2022 / mid-2023. A slow recovery took TVL to ~$53B end-2023 and ~$116B end-2024, then a strong 2025 run to a near-record ~$171B in October 2025 (CoinDesk: ~$170B in mid-Sep 2025, fully erasing Terra-era losses; never quite reclaiming the 2021 ATH on DefiLlama's consistent methodology). A sharp drawdown followed: TVL fell through H1 2026 amid a broad crypto selloff and ~$746M of Q2-2026 exploits, reaching ~$74.5B as of 2026-06-16. All figures use DefiLlama's consistent cross-chain methodology as the primary series; note that other trackers (DappRadar, some press) cite higher numbers (e.g. $202B 2021 peak, $237B in 2025) due to different inclusion/double-counting rules.",
