DeFi lending platforms Aave and Lido together saw about $1.7 billion evaporate from their total value locked (TVL) after Binance disclosed a $6.34 billion hack on Oct. 29, according to CryptoSlate. The incident coincided with a broader $10.8 billion drop in stablecoin market capitalization over the preceding 30 days, intensifying liquidity strains for borrowers and suppliers alike.

Aave’s emergency response and utilization surge

Following the hack, Aave activated an emergency freeze that blocked fresh deposits across 175 V3 and 117 V4 reserves, while still allowing withdrawals, repayments and liquidations. LlamaRisk reported that withdrawals pushed utilization on several large reserves to between 92 % and 100 %, leaving little idle capital and driving up borrowing costs. The protocol also trimmed the upper bounds of its interest‑rate curves temporarily to manage the surge in demand for liquidity.

Lido’s TVL decline amid stablecoin contraction

Lido experienced a $713 million reduction in TVL during the same period, ranking it as the second‑largest loser after Aave. The decline mirrors the overall contraction in stablecoin supply, which fell by more than $10 billion as issuers redeemed USDT and USDC for fiat. DeFiLlama’s dashboard recorded stablecoin market cap at $293.8 billion on Nov. 3, down from $304.6 billion a month earlier.

Underlying factors and broader implications

The Binance breach added a direct shock to DeFi when an exploiter‑linked wallet supplied roughly 60 million USDT to Aave and borrowed nearly 20,000 WETH (about $44.6 million). LlamaRisk’s assessment described the position as over‑collateralized and subject to normal liquidation, but the incident highlighted the fragility of stablecoin‑backed liquidity. Moreover, the stablecoin market was already shrinking before the hack, with DeFiLlama noting a $5.5 billion drop in total market cap from early October to late October.

What to watch next

Analysts will monitor whether Aave restores full collateral borrowing power for USDT, USDC and USDT0, and if Lido can attract new deposits to rebuild its TVL. Additionally, the pace of stablecoin net issuance and any further security incidents at major exchanges will be key indicators of liquidity health across DeFi lending markets.
