Euler Finance

Quick Summary

Euler Finance Suffers Hack Resulting in Loss of $196 Million USD in different assets.




Details of the Exploit

On March 13th, Euler Finance, an Ethereum-based noncustodial lending protocol, was attacked through a flash loan attack which
resulted in the theft of millions in various cryptocurrencies, including Dai, USD Coin, staked Ether (StETH), and Wrapped Bitcoin
(WBTC). According to on-chain data, the attacker carried out multiple transactions and was able to steal nearly $196 million ($8.7
million in Dai, $18.5 million in Wrapped Bitcoin, $135.8 million in Staked Ethereum, and $33.8 million in Circle's USD stablecoin,
USDC). Meta Seluth, a crypto analytic firm, reported that the attack is similar to a deflation attack that took place one month
prior. The attacker leveraged a multichain bridge to transfer funds from the BNB Smart Chain to Ethereum and then launched the
attack. The funds were later deposited into Tornado Cash, a crypto mixer.
