Signed/unsigned arithmetic confusion
Meteora'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 #
Rust type system strongly differentiates i64/u64; signed/unsigned mismatch is a compile-time error in Rust. Release builds use overflow-checks=true (confirmed in dlmm-sdk Cargo.toml). No published audit finding of signed/unsigned confusion found across 8 firms' coverage.
