Isn't it Jump Trading that is out $320M? Didn't they put up the money to make sure the maliciously created Solana tokens were backed by [whatever they're supposed to be backed by]? Jump doesn't own the tokens now, do they?
Jump Trading still has the maliciously created Solana tokens at the end, valued at $320M. They might lose some by Solana inflation but it's not like they're really out of $320M.
