<p>The smart contract wallet of FairWin, a gambling game built on Ethereum which has been accused of being a 'Ponzi scheme,' has been emptied, according to <a href="https://etherscan.io/address/0x01eacc3ae59ee7fbbc191d63e8e1ccfdac11628c#internaltx">data</a> from Etherscan. There was approximately $3 million in ether in the contract prior to a series of withdrawals.</p> <p>Transactions of Etherscan appear to show withdrawals of ether from the smart contract to <a href="https://etherscan.io/address/0x01eacc3ae59ee7fbbc191d63e8e1ccfdac11628c#internaltx">multiple</a> Ethereum addresses. It is unclear whether these withdrawals were from an attacker or simply the users of FairWin in a mad dash to take out their funds.</p> <p>The Block previously <a href="https://www.theblockcrypto.com/linked/41307/ethereum-developers-find-critical-vulnerabilities-in-ponzi-scheme-fairwin">reported</a> that three critical vulnerability was found in the game by Philippe Castonguay, an R&amp;D researcher at Horizon Games. Castonguay told us that there were three main vulnerabilities he discovered, "one allowing the owner/admin of the contracts to totally drain [the smart contract containing $8 million in ether], one where the admin can prevent users from withdrawing forever and one where anyone, not just the owner, can steal new deposits." At that time, the smart contract contained over $8 million in ether.</p> <p>In regards to today's withdrawal, Castonguay tells The Block that "it looks like people raced to withdraw their funds" but added that it is "hard to tell at this point."</p>
