Dependency graph (protocols depended upon)
Circle USYC's assessment for RD-F-050 — scored yellow on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.
Evidence summary #
Dependency graph: (1) USDC ERC-20/BEP-20 for subscriptions/redemptions - all value flows through USDC; (2) Circle CCTP attestation infrastructure for cross-chain operations (BSC 96% TVL); (3) RolesAuthorityProxy 0x902D906b8d988092213bE799B18Bd2cbd64F808C for access control; (4) GenericAggregatorProxy NAV oracle. All four dependencies are Circle-owned or Circle-controlled. Issuer-concentration risk: Circle failure cascades across all dependencies. Yellow due to single-issuer concentration across critical dependencies.
