## Research summary

This review rejects USDD. USDD launched in May 2022 as an algorithmic, TRX-backed stablecoin explicitly marketed as having learned from Terra/UST’s collapse. Weeks later, during the June 2022 Terra contagion, it depegged to $0.9585, roughly 4.2% below peg, and stayed there for nearly two weeks. The token has since been substantially redesigned as "USDD 2.0," a MakerDAO-style collateralized-debt-position system with a Peg Stability Module. The peg held materially tighter through 2025-2026. This review credits that real improvement, though the clean track record since the redesign is under two years and has not yet faced an acute market-stress event comparable to June 2022. Apart from that history, this review could not confirm TRON DAO Reserve’s legal form or jurisdiction from any source. In addition, 82% of circulating supply sits on Tron. The chain’s founder, Justin Sun, faced an SEC suit alleging unregistered securities and market manipulation. The SEC dropped the suit in February 2025, shortly after Sun invested $30-75M in the Trump family-linked World Liberty Financial venture. This registry treats that regulatory-optics fact as material context, not proof of wrongdoing, but it remains unresolved.

## Observable review triggers

- TRON DAO Reserve's legal entity form and jurisdiction are publicly disclosed
- The USDD contract's absence of a freeze or blacklist function is confirmed against deployed bytecode, not marketing claims
- Twelve consecutive months of peg stability through at least one genuine market-stress event, not only calm conditions
- The restricted-jurisdiction list on usdd.io's own interface is disclosed and confirmed not to depend on unresolved regulatory-optics questions
