Optimism Brings Ethereum’s Pectra Upgrade to the Superchain

Optimism has rapidly integrated Ethereum’s Pectra upgrade into its Superchain ecosystem via the Isthmus hardfork, making it the first Layer 2 network to adopt these enhancements. This move reinforces the OP Stack’s commitment to EVM equivalence and shared infrastructure, enabling faster propagation of Ethereum upgrades across a growing network of OP Chains.

Key Ideas

Pectra’s impact on the Superchain: The upgrade introduces blob scaling for lower fees and EIP-7702’s account abstraction, unlocking smart wallet functionality and seamless multichain UX—benefiting both L2 chains and Superchain apps with faster, cheaper, and more intuitive transactions.
Scaling beyond Pectra: While Pectra is a leap forward, Optimism is already preparing for the next phase with proposals like Blob-Parameter Only forks and the upcoming Fusaka upgrade, aiming to further expand blob capacity and support Ethereum’s long-term scalability through innovations like PeerDAS.
