Signed/unsigned arithmetic confusion
ether.fi's assessment for RD-F-018 — scored green on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.
Evidence summary #
Solidity 0.8.x checked arithmetic prevents silent overflow/underflow. No signed-to-unsigned confusion pattern identified in sampled contracts. Certora FV arithmetic invariants provide additional assurance. Cannot confirm exhaustively without symbolic execution.
