Matthew Liu, co-founder of Origin Protocol (OGN), a decentralized sharing economy protocol, wrote an article to disclose the details of the lightning loan attack on the US dollar stable currency Origin Dollar (OUSD). So far, the attack has caused about 7 million U.S. dollars in losses, including more than 1 million U.S. dollars deposited by Origin and its founders and employees. Currently, Origin is determining the cause of the vulnerability and whether it can recover the funds. Origin reminded, "Vault deposits are currently disabled. Please do not purchase OUSD on Uniswap or Sushiswap."
