TVL stability (CoV over 90d)
USDD (Decentralized USD)'s assessment for RD-F-084 — scored yellow on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.
Evidence summary #
Data cache 90-day CoV = 0.361 (mean $1.03B, std $371M, window approx. Feb–May 2026). CoV above 0.30 yellow threshold. Notable anomalies: large step-up ~$650M to ~$1.09B approx. April 14-15 2026 (unexplained — potential large institutional mint or DefiLlama accounting recalculation). Protocol also has documented peg events in June 2022 (~$0.91 floor) and March 2023 (~$0.92 floor) demonstrating peg instability under stress conditions — relevant context for this factor as peg-stability history on a stablecoin.

Methodology #
Compute the coefficient of variation (σ/μ) of daily TVL over the trailing 90 days as a proxy for operational stability.
