Isthmus Mainnet
Important
This is a required upgrade for any Mainnet Superchain node by May 9 as it contains the Isthmus activation on that date. It is unnecessary for other networks.
This is the Isthmus release for the Mainnet Superchain. It schedules the activation of the Isthmus fork on Fri May 9 16:00:00 UTC 2025 (unix timestamp 1746806401).
The following Mainnet chains have the Isthmus upgrade scheduled at this timestamp: arena-z, base, bob, ethernity, ink, lisk, lyra, metal, mint, mode, op, orderly, polynomial, snax, soneium, tbn, unichain, zora. It is mandatory to upgrade nodes for those chains before May 9.
🤝 The corresponding mandatory op-node release is v1.13.2.
Chain operators also need to upgrade their batchers to op-batcher/v1.12.0 before activating Isthmus on their chains.
