Upgrade 16 is an L1 smart contracts upgrade for the OP Stack. We do not expect any downtime or changes in performance.

Chain operators must complete two tasks:

* Deploy new dispute game contracts with new absolute prestates
* Update `op-challenger` to [op-challenger/v1.5.0](https://github.com/ethereum-optimism/optimism/releases/tag/op-challenger%2Fv1.5.0)

Chain operators should be aware that Upgrade 16 involves a one-time invalidation of all existing withdrawal proofs. Users who have proven withdrawals can either finalize withdrawals prior to the activation of Upgrade 16 or will be required to re-prove these withdrawals after the upgrade activates.

If this proposal is accepted, multisig ceremonies will be coordinated to execute upgrade transactions. The following transactions will be executed on the respective chains: `OP`, `Soneium`, `Ink`, `Base`, `Unichain`, `Mode`, `Zora`, `Arena Z`, `Swell`, `World Chain`, and `Metal ` on both Mainnet and Sepolia. Depending on the current state of the chain the execution times will vary. If your Optimism governed chain is not in this list, please reach out to OP Labs Solutions Engineering to coordinate your upgrade. These upgrade tasks will be prepared in the [superchain-ops repo](https://github.com/ethereum-optimism/superchain-ops/tree/main/src/improvements/tasks).
