Quixotic, the largest NFT marketplace on Optimism network shared that a recent update to its contract was exploited. This enabled the hacker to steal approved ERC-20 tokens. While the NFTs appear to be safe on the platform and not affected by the exploit, Quixotic has paused all the marketplace activities related to the platform with the exploited contract permanently paused. Additionally, the platform has vowed to refund all the stolen ERC-20 tokens and assured that users will automatically receive their refunds over the coming days. https://twitter.com/quixotic_io/status/1542790067130978307 Besides being the largest NFT marketplace on Optimism, Quixotic is also a layer 2 scaling solution for Ethereum. With an average transaction fee of just 0.0005 ETH ($1.50), the platform has already saved users an estimated $2 million in gas fees to date, according to data from DappRadar.
XCarnival Recently Suffered Similar Attack
Earlier this week, XCarnival, an Ethereum liquidity provider and an NFT lending pool, lost approximately $4 million after a hacker exploited a flaw in its smart contract functionality. The company decided on suspending the smart contract altogether and offered a bounty of 1,500 ETH tokens to the hacker for returning the stolen funds. The platform also assured that they would not pursue any legal action against the hacker. Interestingly, the hacker actually accepted the bounty and assured that the funds will be returned safely, given the XCarnival CEO signed an official statement stating the same.
