TVL stability (CoV over 90d)

Usual (USD0 / bUSD0 / USUAL)'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 #

Trailing 90-day TVL CoV (2026-02-16 to 2026-05-16) = 0.029 (mean $109.3M, std $3.2M, 90 samples) — mechanically low. However the full-lifecycle context is severe: TVL peaked at $1.87B on 2025-01-07 (ts=1736208000) and collapsed ~94% to ~$104M following the January 2025 USD0++ floor-price governance event. The 90-day window captures only the post-collapse stabilized plateau. The mechanism causing the collapse (locked bUSD0 bond with governance-set floor price) remains in place. The May 2025 exploit (~$43K) was too small to perturb TVL materially. Scored yellow to reflect: current trailing CoV is low, but a catastrophic lifecycle collapse occurred within the past 16 months and the structural risk persists.

Methodology #

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