First-depositor / share-inflation guard
Usual (USD0 / bUSD0 / USUAL)'s assessment for RD-F-075 — scored not_applicable on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.
Evidence summary #
Not_applicable per PD-024 (lending-only factor). Same reasoning as RD-F-074: bUSD0 is a 1:1 lock-and-mint bond with no share-ratio accounting. There is no first-depositor share-inflation attack surface. DaoCollateral mint path issues USD0 1:1 against collateral value, not against a share ratio that can be diluted by donation.
