Reentrancy guard on external-calling functions
QuickSwap'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: UniswapV2Pair uses custom `lock` modifier (reentrancy guard via `_unlocked` state variable) on swap/mint/burn. V3 Algebra: AlgebraPool uses `globalState.unlocked` flag as reentrancy protection set during pool operations. C4 found no reentrancy HIGH — the M-03 (swapping impaired with activeIncentive) is about incentive callback ordering, classified medium not reentrancy exploit.
