According to a report from Decrypt, Fusion Network ($FSN), an interoperability blockchain, was likely hacked early Saturday. In a Telegram post from Fusion Foundation CEO DJ Qian, it was revealed that the Fusion wallet used to swap ERC-20 and native tokens had been compromised. Qian revealed that 10 million native FSN and 3.5 million ERC-20 FSN were stolen in the attack which according to Decrpyt were worth approximately $6.4 million at the time of the hack.
Qian believes that someone with access to the foundation wallet's private keys is to blame and in addition to contacting exchanges the team believes they have evidence strong enough to contact police.
