rubric v1.7.0

Solc version used (known-bug versions flagged)

Chainlink CCIP's assessment for RD-F-170 — scored yellow on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.

Evidence summary #

Three compiler versions: (1) solc 0.8.19 — Router, ARM, ARMProxy, ManyChainMultiSig, RBACTimelock; (2) solc 0.8.24 — OnRamp/OffRamp (Nov-2024 audit scope); (3) pragma ^0.8.4 — MultiOCR3Base library. Known bugs for 0.8.19: StorageWriteRemovalBeforeConditionalTermination (medium/high, optimizer-required at 26000 runs), InlineAssemblyMemorySideEffects (medium, optimizer-required). TransientStorageClearingHelperCollision bug (high, viaIR required) does NOT apply — CCIP uses 0.8.19/0.8.24, both below the 0.8.28 floor. Yellow: medium-severity optimizer-related bugs exist for 0.8.19 with optimizer, but high/critical bugs are not confirmed applicable to CCIP's usage pattern.

Methodology #

Identify the Solidity compiler version used for deployed bytecode and flag if it appears on the known-bug list (solc bugs.json or Vyper 0.2.15–0.3.0 range).
