Deprecated contracts still holding value
Superstate's assessment for RD-F-166 — scored green on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.
Evidence summary #
No officially-deprecated contracts identified. All contracts in profile §3 are active. USTB→Invesco management transition (announced 2026-03-24, expected Q2 2026) retains the same USTB token address per press release — this is a corporate/management-parameter change, NOT a contract deprecation. Repo versioned directories (v1/v2/v3/v4 in src/) represent development history, not deprecated deployed contracts. No evidence of prior-version contracts holding residual TVL.
