Deprecated contracts still holding value

crvUSD (Curve Stablecoin)'s assessment for RD-F-166 — scored not_applicable on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.

Evidence summary #

crvUSD's operational model does not involve formal deprecation-and-abandonment of contracts. Old Controller versions (wstETH v1: 0x584B0Fd8F038fe8AEDf4057Ca3cB3D840446fBbf; wstETH v2: 0x100daa78fc509db39ef7d04de0c1abd299f4c6ce) and PegKeeper v1 (0x6B765d07cf966c745B340AdCa67749fE75B5c345) remain on-chain in a superseded-but-still-operational state, continuing to serve existing borrowers. No governance vote formally declaring any crvUSD contract deprecated and ordering migration has been found. RD-F-166 requires both (1) formal deprecation announcement and (2) deprecated contract still holding value. Condition (1) is not met. PegKeeper V1 docs remain accessible (docs.curve.fi/crvUSD/pegkeepers/PegKeeperV1/), indicating no formal deprecation. Score not_applicable.
