Note
If Lisk Node operators running op-reth client version v1.9 for some reason have to downgrade, they MUST downgrade to v1.8.4 which ensures backward compatibility (part of lisk-node v0.4.3).
It contains the activation of the Jovian hardfork on the Lisk Sepolia network on Wed Nov 19 16:00:01 2025 UTC and on the Lisk Mainnet on Tue Dec 02 16:00:01 2025 UTC.
All Lisk Sepolia and Mainnet node operators must update to this release before the activation timestamp, or their nodes will halt when the corresponding network activates Jovian.
For detailed information, we recommend checking the Preparing for Jovian upgrade guide, the Fusaka upgrade notice and the corresponding OP Stack release notes (linked below).
