Would it help if that paragraph had said "10 OETH"'instead of "10 ETH"? (I am going to go change it regardless, as that is probably at least theoretically less confusing; but, like: is that sufficient?)
I still have trouble understanding how this exploit worked
So... I guess what it boils down to is 'How does Optimism manage it's state trie'? I'd really enjoy a more in-depth explanation for this.
