instruction-introspection

Detect instruction introspection vulnerabilities by scanning Solana programs for sysvar validation gaps and sequence risks. Identify usage of load_instruction_at and get_instruction_relative to map manipulation points and ensure program ID verification.

Instruction introspection in Solana smart contract security is the process of analyzing how programs read instruction data. Auditing this mechanism ensures sysvar address validation and prevents sysvar spoofing during program interactions.

Audit Solana programs for sysvar spoofing risks by validating sysvar address checks and verifying program IDs. Documenting instruction introspection usage helps identify sequence risks and prevents incorrect program interactions.

Yes, you can use instruction introspection analysis to find sequence risks in Solana audits. Scanning for checked function usage and sysvar address validation exposes potential manipulation points and ensures safe invocation patterns.

The best way to map introspection sources during a Solana security audit is to inventory functions like get_instruction_relative. Applying this across audit scenarios detects validation gaps and provides actionable defense guidelines.

Sysvar address validation matters for Solana program security because it prevents sysvar spoofing. Checking instruction introspection usage ensures correct program interactions and verifies that safe invocation patterns are followed.
