Formal verification coverage

Circle USYC's assessment for RD-F-009 — scored not_applicable on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.

Evidence summary #

Not applicable under PD-042 RWA regime. USYC is a permissioned ERC-20 tokenized fund token; there are no DeFi-trustless invariants (AMM invariants, borrow caps, liquidation cascades) to formally verify. Protocol logic is permissioned-transfer with allowlist check plus UUPS upgrade. PD-042 flags formal-verification coverage as a DeFi-tooling-norm factor not applicable for protocol_type: rwa.
