PANews May 10 news, Optimism announced that it has successfully activated the Isthmus hard fork, introducing key features from the Ethereum Pectra upgrade into the OP Stack and Superchain. This upgrade comes just two days after the Pectra launch on the Ethereum mainnet, making Superchain the first L2 ecosystem to support the Pectra upgrade. This upgrade includes Base, Ink, OP Mainnet, Soneium, Unichain, and several other OP Stack chains. Superchain supported nearly 70% of L2 activity in April (based on transaction fees), and each OP chain within Superchain will return benefits to the Optimism Collective in exchange for shared governance, security, and upgrades.
