TVL anomaly — % drop in <1h
USDD (Decentralized USD)'s assessment for RD-F-098 — scored yellow on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.
Evidence summary #
TVL anomaly signal is applicable: USDD circulating supply tracked as TVL (~$1.475B). 30d TVL change +2.77%; 1d change +0.67%; no current severe drop below the 30% threshold. However, the DefiLlama cache shows a historically significant large supply step-up (~$650M to $1.09B in a single day, ts 1774828800 approx April 14, 2026) and an earlier large apparent drop (ts 1750636800, $448M to $96M) in the broader data series — both suggesting USDD supply is subject to large discrete movements that could trigger a TVL-anomaly signal. TRON-side real-time polling not wired in current pipeline (non_evm_substrate: true; Tronscan 403). Yellow: signal would be applicable if live infrastructure were in place; large historical supply swings demonstrate the signal is not a theoretical concern.
