Solc version used (known-bug versions flagged)
Ethena's assessment for RD-F-170 — scored green on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.
Evidence summary #
USDe: v0.8.19+commit.7dd6d404 (paris EVM, 20k optimizer runs). EthenaMinting V2: v0.8.20+commit.a1b79de6 (shanghai EVM, 20k optimizer runs). StakedUSDeV2: v0.8.19 (paris EVM). ENA: v0.8.20. Known bugs for 0.8.19/0.8.20: LostStorageArrayWriteOnSlotOverflow (Low, fixed 0.8.32), VerbatimInvalidDeduplication (Low, fixed 0.8.23), FullInlinerNonExpressionSplitArgumentEvaluationOrder (Low, fixed 0.8.21), MissingSideEffectsOnSelectorAccess (Low, fixed 0.8.21). High-severity TransientStorageClearingHelperCollision (affects 0.8.28-0.8.33 with viaIR) does NOT apply. All known bugs are Low severity and do not affect Ethena's usage patterns.
