April DeFi Exploits Trigger $13 Billion Outflows, Aave Drops 44%

Binance Research reported that April decentralized finance exploits triggered around $13 billion in outflows, pushing the onchain leverage ratio to about 38%. The flight from DeFi protocols was largely traced to a cluster of attacks, the largest being a roughly $300 million exploit of liquid-staking protocol KelpDAO via Layerzero, which sparked a 44% drop in lending protocol Aave's value locked. The leverage reading marks a return to 2021 levels, showcasing a decline in investor confidence across lending markets and decentralized exchanges.

KelpDAO Exploit Drains $13 Billion From DeFi Protocols

Binance Research reported that April's decentralized finance exploits triggered around $13 billion in outflows, draining total value locked across lending markets and decentralized exchanges. The outflows pushed the onchain leverage ratio to about 38%, a reading the firm said marks a return to 2021 levels.

The outflows can largely be traced back to a cluster of attacks, the largest of which struck liquid-staking protocol KelpDAO. KelpDAO suffered a roughly $300 million exploit and later shifted its rsETH token to Chainlink's cross-chain protocol, CCIP, in response.

The breach rattled the wider ecosystem with lending protocol Aave battling a withdrawal crisis as depositors rushed for the exits. Aave suffered a 44% monthly drop in value locked and outflows spread to neighboring protocols. Aave saw billions in deposits exit within 48 hours, and several protocols paused certain operations.

Layerzero disclosed a remote procedure call poisoning incident linked to the $292 million KelpDAO hack, in which attackers corrupted the data feeding the bridge's verification network.

April Records Over 20 Separate DeFi Exploits

April stood out as industry trackers counted more than 20 separate exploits during the month, making it one of the most-hacked stretches on record.

Several protocols migrated cross-chain messaging to alternative providers and tightened verification in response. Protocols migrated to Chainlink CCIP and hardened infrastructure following the attacks.
