Warning
This is a mandatory release for all node operators. It includes the Mainnet timestamps for the Karst hardfork.
The following Mainnet chains will activate on 1783526401 (Wed Jul 8 2026 16:00:01 UTC), pending governance approval: op, ink, zora, mode, lisk, metal, unichain, soneium, ethernity, tbn
Reminder: op-geth has reached end of support, so you must be running op-reth to support the karst activation. For more details on this network upgrade see our notice page.
Important
Operators must use op-reth/v2.3.2 with this release. Prior versions of op-reth will not work with this version of kona-node after Karst due to a new engine API method (getPayloadV5) used after Karst. See the notice page for more details about recommended versions (including flashblocks components).
