The Ethereum Fusaka Hard Fork is expected to take place at the end of 2025.

[The Ethereum Fusaka Hard Fork is expected to take place at the end of 2025] Officials from the Ethereum Foundation stated that the Ethereum Fusaka Hard Fork is expected to occur in the third or fourth quarter of 2025, but the specific timeline has not yet been determined. Ethereum core developer Tim Beiko confirmed that "EOF has been removed from the Fusaka network upgrade" because developers believe that "there is technical uncertainty and it may lead to latency in the launch of Fusaka." EOF was originally planned to introduce a scalable and version-controlled smart contracts bytecode container format through a series of Ethereum Improvement Proposals (EIPs), but it faced opposition due to complexity and the risk of introducing more vulnerabilities.
