Known-exploit function-selector replay
Orca's assessment for RD-F-095 — scored not_applicable on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.
Evidence summary #
Known-exploit function-selector replay. Structurally inapplicable per U10: Solana programs use Anchor instruction discriminators (8-byte hash-derived), not EVM 4-byte function selectors. No public equivalent of the Etherscan 4-byte signature database exists for Solana. The replay-template index is EVM-native and not applicable to Anchor/Rust programs.
