Code complexity vs audit coverage
USDD (Decentralized USD)'s assessment for RD-F-024 — scored green on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.
Evidence summary #
Ethereum ERC-20 is a single-file simple token contract (~200 LOC, low cyclomatic complexity). ChainSecurity has audited ≥5 rounds over 2022-2025. Audit coverage is clearly adequate for this code size. TRON primary audited by CertiK 2022 + ChainSecurity multiple rounds. Green: multiple rounds by two firms for a low-complexity codebase.

Methodology #
Determine whether the cyclomatic complexity or LOC-per-audit-day ratio exceeds the curator-declared credibility threshold for the audit to be meaningful.
