We’d like to thank Infura, QuickNode, and Alchemy for their fast response times,” the team wrote. “We also alerted multiple vulnerable Optimism forks and bridge providers to the presence of the issue. These projects have all applied the required fix.” Optimism is focused on the development of optimistic rollups, which operate at the so-called
