DeFi users pulled billions of dollars from lending and yield platforms over the weekend, cutting total value locked to about $86.3 billion by April 20. (coindesk.com) Total value locked, or TVL, is the dollar value of crypto sitting inside decentralized finance apps. DefiLlama showed sector-wide TVL near $91.0 billion on April 20, down 8.5% in 24 hours, after reports of a roughly $13 billion two-day slide from about $99.5 billion. (defillama.com) (coindesk.com) Aave took the biggest hit. DefiLlama listed Aave near $18.6 billion in TVL on April 20, while multiple market reports pegged the drop from about $26.4 billion at roughly $8 billion to $8.5 billion in less than 48 hours. (defillama.com) (cointelegraph.com) The trigger was not a direct hack of Aave’s own code. CoinDesk reported that attackers exploited Kelp DAO for about $292 million on April 18, then used unbacked rsETH as collateral on Aave, leaving about $196 million in bad debt. (coindesk.com 1) (coindesk.com 2) That sequence is why the outflows spread beyond one protocol. In DeFi lending, users deposit tokens as collateral and borrow other tokens against them, so when a widely used collateral asset breaks, lenders, borrowers, and liquidity providers can all rush to exit at once. (aave.com) (coindesk.com) Aave had already treated rsETH as a risk issue before this weekend. In an April 30, 2025 governance post, BGD Labs said Aave’s guardian should freeze rsETH markets across several deployments after unexpected over-minting was detected in Kelp DAO infrastructure. (governance.aave.com) The weekend shock also hit Aave’s market price and liquidity conditions. Cointelegraph reported AAVE fell nearly 20% to about $89.5 in just over 24 hours, while CoinDesk said a roughly $300 million borrowing spike signaled a liquidity crunch after the exploit. (cointelegraph.com) (coindesk.com) The selloff landed after a long expansion in onchain lending. The Block reported in mid-2025 that DeFi lending had climbed past $55 billion in TVL, with Aave v3 reaching a then-record $26.09 billion, which made this weekend’s reversal unusually sharp relative to the sector’s recent growth. (theblock.co) The immediate question is whether withdrawals slow once bad debt is ring-fenced and affected markets stay frozen. For now, April 20 data still show DeFi smaller than it was two days earlier, and Aave still below the level that made it one of the sector’s biggest balance sheets.
