★ Flash-loanable voting weight

Venus Protocol's assessment for RD-F-036 — scored green on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.

Evidence summary #

GovernorBravoDelegate uses xvsVault.getPriorVotes(voter, proposal.startBlock) for voting weight — checkpointed balance at proposal-start block. XVS token implements checkpoints mapping and getPriorVotes. Flash-loan attack on voting not possible: staked vault balance cannot be flash-borrowed and the checkpoint is historical.
