Aave survived $8.45B in withdrawals, but risk questions remain

Aave handled $8.45 billion in withdrawals without freezing funds, but the episode raised fresh questions about hidden risks in DeFi lending.

When large sums leave a financial system quickly, hidden weaknesses often become visible. In traditional finance, such situations often lead to emergency lending programs, withdrawal limits or government-backed bailouts.

Decentralized finance (DeFi) works differently.

Aave is one of crypto’s biggest lending platforms. In April 2026, users withdrew about $8.45 billion from the protocol after the KelpDAO rsETH bridge exploit raised concerns across DeFi markets.

Aave’s own smart contracts were not compromised. The pressure came from an external rsETH bridge incident that affected Aave through collateral, borrowing and liquidity channels. The protocol’s core logic continued to function, but the episode was not smooth. Some markets came under severe liquidity pressure, and emergency controls were used to contain the damage.

That made the outcome more complicated. Aave avoided a full breakdown, but the event also showed how quickly stress can spread when assets, collateral and liquidity are closely connected.

For Aave founder Stani Kulechov, the event showed that DeFi had become more mature. But independent analysts reviewing the same data took a more cautious view.

While Aave survived, many questioned whether surviving the event was enough to answer concerns about the real strength of DeFi lending protocols.

The pressure did not begin with a hack on Aave itself. It began with the KelpDAO rsETH bridge exploit in April 2026.

Attackers stole about $292 million worth of rsETH from KelpDAO’s LayerZero bridge. That raised concerns about whether some rsETH tokens were fully backed. The concern quickly spread because rsETH was used across DeFi, including as collateral in Aave markets.

This created a direct problem for Aave. If collateral tied to rsETH lost trust or value, lenders could face bad-debt risk. Users began withdrawing funds as they tried to reduce their exposure before conditions became worse.

The withdrawals then added pressure to Aave’s liquidity. As more users pulled funds, some markets became highly utilized. In simple terms, most of the available liquidity had already been borrowed or withdrawn, making it harder for some users to exit immediately.
