Wintermute Trading

Basics

• The OP core team and Wintermute had a 20m OP exploit when using old (9-6-2022) Gnosis Safe code while having multichain deployments. 17m got returned and 1m got sent to Vitalik (10-6-2022) 2m was kept by the hacker 'as a bounty':

"Optimism hired crypto market maker Wintermute to distribute the tokens in a highly anticipated airdrop. But because Optimism sent them to a Wintermute layer-1 address that hadn't yet been synced to layer-2, they were all inaccessible. Wintermute said that the tokens would be secure. But within a day, a hacker stole all 20 million tokens. They were worth $35 million at the time. The address has returned a majority of the OP, and @wintermute_t has committed to reimbursing the Optimism Foundation for the remaining 2mm OP, which was kept as a bounty."
