The FairWin Smart Contract, the creators of which were previously suspected of having organized one of the largest pyramids in the history of Ethereum, has lost all the assets it contained.
According to Etherscan, at the moment of publication the FairWin account balance is equal to zero. On September 26, the value was equal to 49,518 ETH, and on September 21 it exceeded $10 million. Before the last series of asset withdrawals, the balance was about $3 million.
Whether the contract was ravaged by owners, third parties or users is unknown. It is possible that the latter did it against the background of many FairWin security reports. This may be evidenced by the large number of addresses used for withdrawal of funds in the last hours of the scheme, mainly by 15 ETH, which corresponds to the maximum deposit amount.
"People seem to have rushed to withdraw their assets. It's hard to say for sure now," said researcher Philippe Castonguay, one of the first to report problems in FairWin code.
FairWin was promoted mainly in Chinese social networks and was a highly profitable investment scheme, whose clients were offered to earn from 0.5% to 1% within five days. It is supposed that payments to new participants were carried out at the expense of deposits of old, and founders of the smart contract could withdraw money from it.
Until recently, FairWin spent about half of the available resources in the Ethereum network and significantly slowed its performance, until the miners increased the limit from 8 million to 10 million units of gas.
