★ Public initialize() without initializer modifier
USDD (Decentralized USD)'s assessment for RD-F-022 — scored green on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.
Evidence summary #
Ethereum canonical ERC-20 confirmed via Etherscan source: standard constructor with chainId_ parameter; no initialize() function present; not a proxied upgradeable contract. No initializer modifier needed. TRON TVM: proxy upgrade pattern not assessable but TRC-20 tokens do not typically use proxy-initializer patterns. Green for assessable Ethereum surface.
