Loan Protocol Update

On September 8th at 12:17am PST the core developer of the LOAN protocol on the XPR Network, Metallicus, became aware of a highly sophisticated re-entrancy exploit being executed on the protocol affecting Metal X DeFi lending market smart contract (lending.loan) by accounts “letsgop” and “letsgopuppy”. Upon becoming aware of this attack the appropriate measures were immediately taken to halt all mint/deposits, redemptions, borrows, repayments and liquidations. Additionally, our operational defensive security measures kicked in and funds were immediately frozen and secured. During the incident the following funds were unwrapped before detection: 2868071.411598 DOGE, 17.00633643 LTC, 189935.044555 XRP, 0.00179913 BTC and 0.0304795331175 ETH
