On February 10, Freeman tweeted about the finding and noted, “Last week, I discovered (and reported) a critical bug (which has been fully patched) in @optimismPBC (a “layer 2 scaling solution” for Ethereum) that would have allowed an attacker to print arbitrary quantity of tokens, for which I won a $2,000,042 bounty.” He added: ” will be giving a talk about the bug at @EthereumDenver, Friday, February 18th: 9:40am MST on the Infinity Stage. My talk will be live-streamed, presumably to the #ETHDenver YouTube channel: https://youtube.com/c/ETHDenver Look out for “Attacking an Ethereum L2 with Unbridled Optimism”!”
