Solc version used (known-bug versions flagged)

M^0's assessment for RD-F-170 — scored green on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.

Evidence summary #

Core contracts: solc v0.8.23+commit.f704f362, EVM Shanghai. WrappedM impl: same v0.8.23. SwapFacility/HubPortal proxy: v0.8.26. HubPortal impl: v0.8.34, EVM Cancun. None of these versions have known high/critical bugs affecting normal Solidity code. Solc 0.8.23 fixed VerbatimInvalidDeduplication (low severity, pure-Yul only). 0.8.26 and 0.8.34 are later safe versions.
