The malicious actor that perpetrated the theft of 20 million Optimism (OP) tokens from the cryptocurrency market maker Wintermute has handed back 17 million of those coins to the address of the Optimism contract.
According to the findings of Etherscan, there were 17 separate transactions involving one million OP tokens each, the first of which took place at 12:09 PM UTC and the last of which took place at 12:31 PM UTC on Friday.
As of the time this article was published, the exploiter still had one million OP tokens in the wallet after using them. The hacker had earlier given one million coins to Vitalik Buterin, who was one of the co-creators of Ethereum. Immediately after the hack, the hacker also sold another million coins.
A prior commitment made by the attacker to refund the cash has been fulfilled now that they have done so, despite the fact that they are short 3 million tokens. In the beginning, Wintermute had granted the hacker a week to restore the cash, and in exchange, the hacker had promised not to take any legal action.
Because Wintermute gave an undeployed multi-signature wallet to Optimism in order to collect a 20 million OP token award from the latter, the hacker was able to access the cash.
