Dependency graph (protocols depended upon)
Usual (USD0 / bUSD0 / USUAL)'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 #
Protocol depends on: (1) Hashnote (USYC NAV oracle + BNY Mellon custody — ~83% of collateral), single point of failure for collateral backing; (2) Spiko (USTBL); (3) M0 Foundation (M token); (4) Chainlink (price feeds); (5) LayerZero Endpoint V2 (OFT cross-chain); (6) Chainlink CCIP (USUAL cross-chain). USYC/Hashnote dependency is dominant and concentrated. Yellow because failure of any single dependency degrades protocol; red avoided because collateral is fully backed (not leveraged) so failure mode is operational halt rather than immediate insolvency.
