Ethereum’s Fusaka upgrade arrives in November 2025, quietly boosting scalability and network resilience without changing smart contracts
Ethereum’s upcoming Fusaka hard fork is slated for early November 2025, setting the stage for one of the most consequential Ethereum network upgrades in years.
Unlike Pectra, the May 2025 fork that delivered visible changes like account abstraction and higher staking limits, Fusaka operates behind the curtain. It bundles 11 Ethereum Improvement Proposals focused on scalability, node resilience and efficiency, leaving smart contracts untouched.
