Hey,
adding the previous proposal for context : Proposal: Nexus Covered Vaults (Discovery Phase)
Do you think possible at this stage to estimate the Development Roadmap & Budget for Phase 3?
If I understand correctly, if this proposal is accepted, there will be a Phase 3. I personnally feel a bit uncomfortable accepting without an idea of how much it’s gonna cost to complete the project. Without it, you could ask for an unreasonable amount for Phase 3 and Nexus would be in a bad spot : " either we wasted money on phase 1&2 or we spend this unreasonable amount for phase 3 " (Not saying it will happen here ofc, just a general comment 
).
Cheers
