Grant Description:

• Develop small project responsible for automation of MEV Blocker Billing process.

Milestones:

Milestone 1: Submit the billing data for period on chain

• Execute the relevant Dune queries (Fee per Block & Payment Due) for the prescribed billing period and retrieve the execution results.

• Combine the query results and write the billing data to the MEVBlockerFeeTill contract by invoking its bill function.

This is to be containerized and run on a weekly schedule.

Note that Milestone 1 is already complete and can be found at https://github.com/cowanator/mb-billing under release tag v0.0.0.

Milestone 2: Check Payment Status of Builders

• At some point after the billing date (and before the next), verify that the requested fees have been paid.
• If not paid, invoke the draft function to deduct the fees from the builder's bond.

Milestone 3 [Optional]: Professionalize query maintenance and transaction submission

1. Store and maintain the relevant queries in the project repo, whenever they are updated on main, the Dune Query Updater workflow is triggered to save the changes.
2. Instead of direct contract call from EOA, propose a Safe transaction along with an approval notification.
