Historical bad-debt events

USDD (Decentralized USD)'s assessment for RD-F-067 — scored not_applicable on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.

Evidence summary #

No lending markets, no borrow positions, no bad-debt-socialization mechanism. USDD operates a CDP (collateral → mint stablecoin) model; there is no lender/borrower pair that can generate bad debt in the traditional lending sense. The peg events (June 2022, March 2023) are reserve-management events, not bad-debt events. Data cache hacks: [] confirmed. PD-024 lending-only N/A applies.
