Another day, another DeFi hack. Arcadia Finance has reportedly been the victim of an exploit which allowed hackers to drain roughly $455,000.
Decentralised finance (DeFi) platform Arcadia Finance has reportedly become the latest victim of a hack. Blockchain investigating firm PeckShields reported the exploit and said it was due to “the lack of untrusted input validation.”

PeckShields alerted about a code vulnerability that allowed a hacker to drain funds worth about $455,000 from Ethereum (darcWETH) and Optimism (darcUSDC) vaults. According to the firm, the code vulnerability lacked a validation mechanism to cross-check unverified inputs. It added, “There is a lack of reentrancy protection, which allows for the instant liquidation to bypass the internal vault health check.”
PeckShields also reported the exploiter transferred roughly 179 ETH by bridging 148 ETH and swapping 59,000 USDC to crypto mixer Tornado Cash.
Arcadia TVL Drops 76%
Following the hack, DeFiLlama reported that Arcadia’s Total Value Locked (TVL) dropped by a staggering 76%, from $605,000 to $145,000.
The exploit on Arcadia Finance comes only days after a $130 million hack on Multichain’s MPC bridge platform.
Observers noted $102 million worth of crypto was withdrawn from the Multichain Fantom bridge on the Ethereum side. $666,000 worth of Dogecoin (DOGE) and $5 million from Moonriver were also removed. An additional 7214 Wrapped Ether tokens, 1024 Wrapped Bitcoin, and $58 million worth of USDC tokens were drained from the Fantom bridge’s Ethereum smart contract.
Arcadia Acknowledges Exploit
Arcadia Finance acknowledged the exploit on their protocol but has yet to provide further information.
The platform informed its users this morning that it had contacted the hacker.
