According to the source, nearly $8.5 million has been already been moved. As a result, the Platypus USD stablecoin became depegged and dropped 52.2% to $0.478 at time of writing.

A flash attack is the same method used by Avi Eisenberg when he allegedly manipulated the price of Mango Markets MNGO coin in October. Eisenberg said shortly after the exploit that he believed “all of our actions were legal open market actions, using the protocol as designed.”

Platypus has not yet made a public statement on the incident.
