Dependency tree uses EOL Solidity version

Ethena'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 #

All four core contracts use Solidity 0.8.19 or 0.8.20, both active/supported versions (not EOL). Foundry toolchain confirmed (foundry.toml present: optimizer=true, optimizer_runs=20000, evm_version=shanghai). forge-std is a development dependency, not a production dependency. No EOL Solidity version usage.
