Summary

Add a minimum bid parameter to the MEV strategy to allow setting a minimum bid to accept a block from a relay.
Ideally a top-level minimum bid as well as overrides per relay.

Motivation and Context

flashbots/mev-boost#273

Implemented in flashbots/mev-boost#274

This feature should now be available in the https://github.com/attestantio/vouch/tree/execution-config-v2 branch. If possible, please compile this branch and run it in your test environment to confirm that it meets your requirement. If not, please read https://github.com/attestantio/vouch/blob/execution-config-v2/docs/executionconfig.md for the same.

That sounds perfect.

I'm currently running from docker, so would be easier if there was a docker tag I could use.
I have less than 10 validators running Vouch on Prater so might take some time until I propose blocks above/below the min_value to confirm.

Please try attestant/vouch:execution-config-v2

Any feedback on this PR? I'm looking to merge it in the coming week so any information you may have on it would be appreciated.

I successfully proposed a block with the attestant/vouch:execution-config-v2 version on Xmas' eve, which included MEV as it was above the min bid (0.02): https://goerli.beaconcha.in/slot/1b84d33040e60e46b2f83b23382288d6beec94941a03fc026b4c05a44609d7ae

I didn't notice any additional log mentioning the min bid was met (running level info), but it did propose correctly so no concerns.

Thanks for the feedback.

Just an update that I was still running attestant/vouch:execution-config-v2 and noticed it produced a block with a relay below its configured minimum bid a few days ago.

The logs don't tell much, the Flashbots one, which had the highest value (but below its min bid) was selected:

That's the highest value (0.037158), but below min value of 0.04 set for that relay:

}

Is my config wrong or is that a bug?

Thank you for reporting this. It is a bug in the selection mechanism for bids, with a fix in #121 that will be included in release 1.7.0.
