Code complexity vs audit coverage

deBridge'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 #

33 audit reports from 4 firms covering EVM, Solana, SDK, infrastructure, and operations. Audit coverage relative to code size appears substantial. DLN contracts (DlnSource.sol ~500 LOC, DlnDestination.sol ~400 LOC) were audited by a dedicated engagement in 2023-04-13 and supplementary audits (External Call 2023-09-25, EVM Bridge 2024-06-18, EVM Upgrades 2024-12-30). Code complexity is moderate for a bridge protocol. No evidence of audit-scope-to-LOC ratio red flag.

Methodology #

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