SELFDESTRUCT reachable from non-admin path
Usual (USD0 / bUSD0 / USUAL)'s assessment for RD-F-011 — scored green on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.
Evidence summary #
Contracts compiled with Solidity 0.8.20/0.8.22 and Shanghai/Paris EVM targets. EIP-6780 (Shanghai) restricts selfdestruct to contracts created in the same transaction, effectively neutralizing this vector. All contracts use upgradeable proxy pattern without self-destruct functionality.

Methodology #
Determine whether any deployed contract contains the SELFDESTRUCT opcode in a code path reachable from a non-admin caller.
