We have submitted a formal proposal to the Zcash Community Grants Committee, and you can view it here:
We have narrowed the scope to building the bridge software and deploying it to testnets. This would allow us to begin building while discussions continue about how to fully deploy it to connect the Zcash and Avalanche mainnets (Part 2), and about how to connect it to a new Zcash-on-Avalanche Subnet (Part 3).
Thank you for your consideration.
