CREATE2 factory permits same-address redeploy
Falcon Finance's assessment for RD-F-144 — scored green on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.
Evidence summary #
No CREATE2 factory-based redeployment pattern identified. Standard OZ TransparentUpgradeableProxy and Safe Proxy Factory 1.4.1 patterns used. No redeployment-to-same-address risk.
Detail #
USDf and sUSDf use OZ TransparentUpgradeableProxy (not CREATE2-based). Admin Safe created via Safe Proxy Factory 1.4.1 (standard Safe factory deployment, not CREATE2 with arbitrary salt for reuse). No protocol-level CREATE2 factory identified.

Methodology #
Determine whether a CREATE2 factory deployment allows redeployment to the same address with different bytecode (via selfdestruct + redeploy pattern).
