Reentrancy guard on external-calling functions
SUNSwap (sun.io)'s assessment for RD-F-014 — scored green on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.
Evidence summary #
V2 Pair implements custom lock mutex (uint private unlocked=1) applied to mint/burn/swap/skim/sync — standard Uniswap V2 reentrancy guard pattern. V4 uses flash accounting (differences settled end-of-tx) reducing reentrancy surface. V3 follows Uniswap V3 well-audited upstream pattern.

Methodology #
