What Accelerate does
Under the Accelerate heading, the screen reads Accepting bids closer to your deadline captures more MEV. Accelerate measures what that would have been worth on the blocks you propose, and recommends a cutoff from your own slots.
Accelerate recommends the bid cutoff for the MEV sidecar you already run, so a proposal can take a better bid without waiting so long that the block is late. The number comes from slots your validators already proposed. You upload the sidecar configuration you run, read the recommendation, and download a config to deploy yourself. Console never writes to your infrastructure. Nothing on this screen changes validator behaviour until you deploy that file.
Who can use it
The sidebar shows Accelerate when Optimum has enabled it for your organisation and you have at least 200 active validators on mainnet. It is offered to entity accounts, which is who reaches that number. Registering as an entity does not enable it. An individual account with at least 200 active validators on mainnet can be enabled the same way. See Account type.
A cutoff recommendation, once you are on the screen, still needs 200 measured proposals. Readiness.
If Accelerate is not in the sidebar, your organisation is not enabled or it has fewer than 200 active validators on mainnet. Below that number the entry stays hidden. Otherwise ask support. There is no other URL to use.
The steps
- Start Accelerate — prerequisites, including the disclaimer.
- Recommendation — your config, and the recommended bid cutoff once the window can support one.
- Adjust — you set the cutoff on the sliders, download the config for MEV-Boost or Commit-Boost, and record what you deployed.
Where you land on a return visit follows what is already stored. No acceptance sends you to step 1. Acceptance without a saved config sends you to the recommendation. A saved config sends you to adjust. If the terms change, the previous acceptance no longer counts and you start again.
When a measurement cycle finishes and you have not answered it, Accelerate in the sidebar shows 1, and the screen leads with Your measurement cycle is complete. Review the recommendation opens step 2. Dismissing hides that notice until the next cycle completes.
What it measures
Every figure is measured on slots you already proposed. The figures sit on this screen, under MEV outcome. See Acceleration.
Before you accept the terms, the top of the screen says Accept the terms to see your modelled gain. After you accept, that place shows the annual figure: what a later bid cutoff could have captured on the slots you propose, from the simulation the terms describe. See Readiness.
Older names on some screens
The sidebar entry and the screen heading are Accelerate. Results are MEV outcome on that screen. There is no MumBoost item under Performance, and the title MEV Cutoff Optimisation is not on this screen.
A direct link to the older report can still show two MumBoost messages: Could not check the MumBoost terms, and This operator has not accepted the MumBoost terms. Both mean the same check on Accelerate. See Acceleration.
