Deprecated contracts still holding value

BENQI'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 formally deprecated contracts identified. qiBUSD (0x872670CcAe8C19557cC9443Eff587D7086b8043A) is listed in docs but its market parameters were tightened via governance (collateral factor → 0) following BUSD's global wind-down by Binance (Feb 2023). Per the briefing's explicit precedent rule: Compound-fork parameter restriction (CF/RF → 0) is NOT contract deprecation and should not be over-scored. No formal deprecation announcement found. BUSD effectively ceased circulation by 2024, so residual qiBUSD TVL is assessed as negligible. Threshold: green = deprecated contracts hold $0 or have been self-destructed. Curator-verify flag: confirm qiBUSD.totalSupply() on Snowtrace.
