Arcadia Finance, a non-custodial protocol that supports on-chain cross-margin accounts, was recently exploited according to PeckShield data. Arcadia Finance is a platform that allows users to collateralize portfolios, access up to 10 times more capital, and interact with other protocols using their deposited collateral and borrowed funds. In this article, we’ll take a look at the attack and how it affected the Optimism network.

Details of the attack
A community contributor from PeckShield, a reputable cybersecurity firm, recently identified an exploitation incident involving Arcadia Finance on both the Ethereum and Optimism networks, resulting in a loss of approximately $455,000.
The exploiter acted quickly by transferring a total of approximately 179.3 ETH from Optimism[OP] network. This amount was obtained through a combination of 148 ETH bridged from the Ethereum network and 59,000 USDC traded.
The destination of these funds was Tornado Cash, a decentralized privacy solution for cryptocurrencies. By transferring the money to Tornado Cash, the exploiter probably wanted to obscure the transaction history and make it more difficult to trace the source of the money.

The attacker used a process known as frontrunning to exploit the protocol. Front running means that an individual executes a transaction for others in a block. The frontrunner gains an advantage by prioritizing its trade to capture profitable opportunities. This practice may allow them to take advantage of price differences or manipulate trades to their advantage.

How’s Optimism?
In addition, the operation of Arcade Finance may also negatively impact the Optimism network. According to data from the token terminal, the growth of daily active users on the Optimism network remained high, showing a 3.9% growth over the past week. However, the revenue generated by the protocol fell significantly. Over the past seven days, sales generated by Optimism fell 52.6%,
This drop in sales could hinder Optimism’s long-term growth.
