Flash-loanable voting weight

Yearn Finance'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 #

Governance voting via Snapshot space veyfi.eth uses veYFI which is non-transferable locked YFI (1-week to 4-year lock, Curve veCRV-class). Non-transferable = not flash-loanable by construction. Voting power decays linearly with remaining lock time. Cannot be acquired in a single block.
