★ Reinitializable implementation (no _disableInitializers)
USDD (Decentralized USD)'s assessment for RD-F-143 — scored not_applicable on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.
Evidence summary #
Not applicable. Canonical Ethereum USDD ERC-20 (0x4f8e5de400de08b164e7421b3ee387f461becd1a) is a direct non-proxy implementation with constructor(uint256 chainId_) — no initialize() function, no proxy pattern, no _disableInitializers() requirement. TRC-20 on TRON: TVM, not EVM proxy architecture. N/A by contract structure and substrate.

Methodology #
Determine whether the implementation contract does not call `_disableInitializers()` in its constructor, leaving re-initialization possible.
