Dependency tree uses EOL Solidity version
SUNSwap (sun.io)'s assessment for RD-F-174 — scored yellow on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.
Evidence summary #
V2/V3 operative contracts (~$352M combined TVL) compiled on Solidity 0.7.6 which is EOL (last 0.7.x release 2021; all security work in 0.8.x+). V4 uses 0.8.26 (current). No forward-compatibility migration of V2/V3 to 0.8.x has been made.
