I support this proposal. Developing monitoring infrastructure for Cow AMM and MEV Blocker should provide the team clarity on these areas.

Please kindly check the snapshot. Particularly it is misleading that there is reference to “Core contributor Solver Engineer (Oct 2024 - Dec 2024 inclusive).” It’s fair that this is in the previous grants, but it should not be towards the header. Please kindly make sure that the grant aligns with the template.
You are able to unilaterally withdraw the snapshot (it can be deleted by the creator) - then subsequently edit it and set it up again please.

Thanks for your past work, I support this proposal in continuation.
@Sailjunkie as just mentioned by mfw78, there is indeed an error on what you posted in Snapshot, and I also think it would be better to remove this one and repost.

Hey @Sailjunkie
Your Grant didn’t reach quorum - I assume it was because it was posted just before a weekend and there is only three day voting period for the grant committee.
I would recommend to re-post today and I can amplify with the grant committee to get some eyes on it.

@Sailjunkie Could you report your hours up and including February (to date)?
The payments will be processed in the next couple of days.

Hi,
From Jan 13th to Feb 21st I worked 6 weeks \* 15 hours = 90 hours. Thereby requesting 3600€.
Progress involve, many internals requests on MEV Blocker performance metrics and a report which is underway, and a new database for CoW AMM preformance metrics to improve the current dune dashboard efficiency and readability.

Hello,
I worked 15 hours for the 4 weeks, thereby requesting 2400€.
This period’s work includes the finished version of the MEV Blocker report. And a complete refactoring of the CoW AMM dashboard for improved metrics.
I think that the previous payment was wrongly processed accounting only 2400€ instead of 3600€ (see [tx](https://gnosisscan.io/tx/0x34f8da6826356a2927183fb469b06224c5eefec2a5d41d1e1489374c19472de2)). Therefore, this month payment should be 3600€ (= 2400€ + the missing 1200€).

@harisang could you confirm the new amount.
Sorry about the previous payment - you can flag these anytime to us if something is processed incorrectly. I’ll add the difference!
