Hello!
This is an exciting Mission request!
I wanted to share the work that Tally.xyz has done in the past for the collective for cross-chain voting.
RollCall - a cross chain library for doing cross chain governance built on OP.
Superchain Governance DeepDive - a research project in to implementation techniques for cross chain governance in on Optimism and across the super chain
MultiGov - A powerful product solution built by Tally, Wormhole and ScopeLift that enables universal MultiChain governance.
Tally would be very interested to continue its work in this area and has the expertise on the subject matter. We would be happy to discuss more.
