delegatecall with user-controlled target

BENQI's assessment for RD-F-012 — scored green on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.

Evidence summary #

BENQI lending uses Compound V2 delegatecall proxy pattern (Unitroller→Comptroller, QiErc20Delegator→QiErc20Delegate). In QiErc20Delegator._setImplementation(), the implementation address is admin-controlled — not user-supplied. Source inspection confirms delegatecall target is fixed by admin, with no user-controlled path to the delegatecall target.
