Dependency tree uses EOL Solidity version

Superstate's assessment for RD-F-174 — scored green on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.

Evidence summary #

Current deployed implementations use solc v0.8.28 (USTB impl SuperstateTokenV5_1) and v0.8.28 (USCC impl 0x9b7282Cb). Solidity 0.8.x is the current supported branch (non-EOL). The older implementation 0x5419d3FA uses v0.8.20 but is no longer the active implementation pointed to by the proxy. OZ upgradeable v4.9.3 (pinned submodule) is a supported release.

Methodology #

Determine whether the deployed code or its dependencies use an EOL or unsupported Solidity version without a forward-compatibility patch.
